"February Assignment: Depth of Field "
Sat 02-Feb-13 03:46 PM by avm247

Rancho Cordova, US
          

Depth of Field is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Depth of Field is controlled by the Aperture during exposure. Typically Depth of Field extends 1/3 in front of the subject and 2/3 behind the subject. Several factors effect Depth of Field: the aperture, the format (FX vs. DX), focal length.

Generally, shallow Depth of Field can be had with large apertures (f/1.4, f/1.8, f/2) and deep Depth of Field with small apertures (f/11, f/16, f/22).

Your assignment is to shoot a scene, still, what ever you want and experiment with depth of field. Isolate a subject, get it all in focus. Explore how changing the aperture affects the final output of the scene.

If you have a zoom, try one end, wide and explore the apertures then try the tele end. See how DoF changes as you shoot.

Post images you like and why. Take notes (you don't have to, but it will help you figure out what's going one).

Edit to add:
Only rule here: use a Nikon.

Most excellent! What is your criteria for a newb? I have been on the site for 9 months so I'm not sure I qualify as a newb. I will still carry out the assignment but who do you want to post pictures. I would hesitate to rule out anyone because I learn as much from seeing the possibilities from you experienced guys as I do from my experiments. My suggestion would be to have these assignments span a couple months and for the first month only the new to dslr people post their photos, then in the second month open it to everyone so we can see examples of all levels of experience. If you all agree you just need to set the criteria for who would be considered a newb. Did any of this make any sense to anyone but me!

This is open to anyone, from a person with zero experience to a person shooting a long time in auto or program modes. What I want to do (hopefully) is get photographers to build a skill set beyond their comfort level.

I think that opening the assignments to everyone gets everyone involved in the discussion. We all have different levels of experience and I don't want to exclude anyone.

The only way to learn is to practice.

Nice example!

Note to the participants: DOF, whether deep or shallow, is best shown in large pictures. So, doing what Anthony did by uploading the large version to your gallery and linking the smaller version into the message works really well.

Just playing around with macro thought this was a neat subject liked the colors. And the out of focus blur is very interesting on the body.

Cool! How does depth of field change in macro?


Edit to: did some reading here and I see references about how in macro DOF is paper thin. In such a case can you increase DOF at all? Just curious.

With Macro Photography, DoF is VERY shallow, expecially approaching 1:1 or beyond in reproduction, even when shooting at f/16 or f/22.

One technique used to achieve a complete subject in focus is to stack images where multiple images of the same subject are shot, with different areas in focus, front, middle, back then combine the images together. (I haven't done this.)

Macro changes a lot of rules, and I want to relearn those again, so rest assured, we'll do something with it.

Awesome shot! Love the little lint hanging off the "mouth." Lovely color and bokeh, too - very creamy!

(Bokeh, is a Japanese term meaning out of focus highlights.)

Thanks for posting the tech info, too!

Here's my first attempt. Not a mind-blowingly awesome composition but I think it shows how aperture affects depth of field.

All shots were taken using D5100 & 18-55mm kit lens on aperture priority.

Good example Rob. You can try setting the Lens 18mm getting as close as you can and shooting at F3.5 to see if you can get even more isolation on the nobs. Curious to see if there is much difference in 3.5 to 5.6

Here's a couple of shots with the lens @ 18mm as promised. Closest I could get to the first knob was 15cm (about 6in).

There's definitely a visible difference between f3.5 and 5.6 - the difference can be seen on the second knob.

Hi Tracy.

Quite simple, really. I created a blank image in Photoshop that fit into the restrictions for the gallery (1800px on widest side). Then I pasted and resized the originals to fit into that space.

You don't need any big post-processing software.

If you shoot in JPEG format, you could use something like Windows Paint (assuming you're use a PC running Windows) to do the same.

If you shoot in RAW, then there would be an extra step to convert your photos to JPEG.

Sure, no problem.

It's nothing fancy. It's a Yamaha Pacifica PAC212VFM I bought on impulse. I've been learning to play guitar(at a very slow pace) for about a year on an acoustic and this one caught my eye while I was browsing through a local music shop. So now I alternate my learning between acoustic and electric.

Only modification from the original are the Tonerider pickups and thicker strings than what came standard - makes it sound so much better, to my untrained ears anyway.

Oh, and the colour is listed as Caramel Brown although it's closer to the image I posted. The image is slightly warm because of my WB setting (cloudy)

I don't have a shot of the full guitar , but it looks like:

While I am not a beginner, I would like to add some food for thought. Being a landscape photographer, I want everything in acceptable focus. My photo was taken at Lake Junaluska, NC and demonstrates Perspective, DOF, and Hyperfocal.

I wanted to take a shot of this bridge to get a nice perspective example. If I had let the camera auto focus, the camera would have focused on infinity and the bridge and hand rails in the forground would have been out of focus. That would have been very distracting. The solution, focus on the Hyperfocal Point using a small aperture (large number) and wide focal length. I used F11 and 16mm which puts the Hyperfocal Point at 3.7ft or 1.1meters. By focusing on this, I knew that half the distance from the point back towards the lens or 1.85ft would be in focus. Lock in focus by switching to manual focus or holding the shutter half down and recompose the shot and fire away. Everything from 1.85ft to infinity will be in acceptable focus.

Very cool thanks for the example and explaining the use of hyper focal length. BLW answered some of my questions about it in another thread. It is great to see examples! Sadly weather here has been to cold and nasty to do much outside with my d3200.


Edit to add: not to leave anyone out others also helped me with hyper focal I. The other thread. I just remembered BLW off the top of my head because his initial post stuck in my head. Thanks to all of you!

Thanks, John

Back in the old days, before zoom lens, the DOF scale was right on the prime lens and you could just manually focus to the hyperfocal point.

I use the hyperfocal focus about 90% of the time. Focus is one less thing I have to think about, leaving more time for composition. If I had to pick one thing that has helped me with photography, it is hyperfocal.

Can we get more info on Hyperfocal Point(meaning). I'm not new, and am not familiar with this at all. Have only heard about it a few times.

From the Nikonians wiki: The closest point at which a lens can be focused where the depth of field includes infinity, starting at half the hyperfocal distance

A useful thread can be found here. Another thread here.

Had a good laugh at this statement - "The Circle of Confusion (CoC) has nothing to do with other camera brand users."

So, if my thinking is right, basically if my hyperfocal distance is 2m, everything from 1m onwards should be in focus, right?

At what focal length? Did I miss understand the hyper focal distance is depends t on focal length? If so then you numbers may be correct depending on which lens if a prime or focal length used on lenses with variable focal lengths.

The numbers I put in there were just to clear up my understanding of the definition - in other words, they were thumb-sucked and are not specific to any focal length

Or in other words - if hyperfocal distance is X (2.0m as an example) and your focus point is at that distance(X), anything from distance X/2(1.0m) to infinity should be in focus.

Hope that explains it better.

Rob

The Hyperfocal Distance does change with Aperture and focal length. Most landscapes are shot at wide focal lengths such as 16mm or 18mm. Some photographers like to shoot much wider, but I have found that I like to stay around 16mm or so. Also smaller apertures (larger numbers) such as F11 or F16 are used. Shooting wide at small apertures will maximize the DOF. At one time the Nikonians had a printable hyperfocal chart that you could carry in your bag. I carry one all the time. I have emailed JRP to see what happened to the chart because I cannot get the link to the chart to work. I will post the link if he is able to provide one.

I shoot most of my landscapes at 16mm & F11. Now if I were using an 18-55mm I would use 18mm & F11. My Hyperfocal distance to focus on would be 4.7 feet away. Lock in your focus by holding the shutter 1/2 way down or by setting the lens on manual. Now recompose and shoot.

Here are a couple settings you can try until I can find a chart to post:

APERTURE/ FOCAL LENGTH/ HYPERFOCAL DISTANCE IN FEET
F8 / 18mm / 6.6ft
F11 / 18mm / 4.7ft
F16 / 18mm / 3.3ft

F8 / 24mm / 11.8ft
F11 / 24mm / 8.4ft
F16 / 24mm / 5.9ft

If you will focus on the Hyperfocal Distance (Hyperfocal Point as I call it) 1/2 half the distance back toward the lens to infinity will be in acceptable focus. Example: F11 & 18mm will give you 2.35 ft to infinity in acceptable focus.

Now, this is not brain surgery and you do not have to carry a measuring tape with you. I just aim at something approximately 5 ft away. Guess at it by judging from your height.

No measuring with this photo, I just focused on the closest bricks and shot away.

Thanks a stack for all the detail. It does make a lot of sense to me.

My landscapes were usually the "point at the mountain and hope for the best" types
As they say, one learns something new every day.

As for the chart, I have now downloaded the Nikonians DOF calculator onto my phone, so that should be just as good as a printed chart - until my battery dies, that is

Thanks again for the info.

Rob

Those are pretty nice charts!

JRP emailed me back and said they were working on the links and that was why I could not get to the Nikonian Charts. He attached them to the email so if you want them just shoot me an email. The Nikonian ones are for FX & DX and are in Feet and Meters. Hopefully they will be back on site soon.

Jerry got mine also thanks. Curious just how effective are hyper focal lengths with longer focal lengths?

That is a good question, John, to tell you the truth once I am passed 50mm I have never tried them. I have always tried to get maximum DOF so I do most of my landscapes on the wide end.

We've gotten a bit off track and that's okay. Let's get back to posting images. We can start a new topic if you want to continue the discussion on hyperfocal distance.

Here is a DOF shot I took not too long ago. Now I know we can get this effect with either small or larger apertures and so on, but this was done in conjunction with a SB700 on board shot at 1/40 sec and aperture set at f/2.8. Spot metering,

I attended a beginner workshop this past weekend and one of the things discussed was depth of field. When it comes to controlling depth of field, I think most people know that aperture is what controls it, but we were also shown that camera/subject distance as well as lens focal length also have an effect on depth of field.

The image set below is one I took to show that subject/camera distance changes the depth of field. All images were taken at 42mm & f5.3 (no specific reason for those numbers). I have cropped all 4 images to get them more or less the same viewing size - makes it easier to see the effect.

Nothing apart from the subject to camera distance (measured from the front of the lens) changes. I didn't correct for the changing angle as the camera got further away, though, but I don't think that would have had a great influence anyway.

#1 Attempt at shallow depth of field. D5100, ISO100, f/9, 1/320sec


#2 Shallow depth of field. D5100, ISO 1600, f/4.2, 1/250sec


#3 Well, I was going for shallow here but the ship still looks pretty in focus to me. D5100, ISO 100, f/4.5, 1/2500sec

Dog go e I so want a Bahamas mama now! Lol nice shots. The last one with the sail boat, I would find that hard to isolate seems you would need to be closer to the subject. Post might be the best place to do some background blurring.

With that lens out of focus blur would be hard to achieve depending on subject distance. I think even a 2.8 wouldn't produce ideal blur and isolation. Best bet would be a 1.4 the shot was at 42mm as per exif data. There were possibilities. 50mm 1.4 or even 1.8

Would it have been different had I moved back & shot at 200mm instead of 42mm? I remember hearing recently the long focal lenght, the more the background compresses.

I am brand new to photography and I had just bought a V1. I finally was able to get outside to snap a couple photos during the day with my new 1 Nikkor 10mm F/2.8 lens. I went shot at the extreme apertures here.(If that's how you describe that.)

That's a great question. I think it will once you get so far. But i'm not sure what that distance is. Hopefully some one that knows will chime in.

Since depth of field is affected by focal length, I'd say yes, you would have got a shallower depth of field with the 200mm lens.

How much shallower exactly, I'm sure someone can calculate

Yes, shooting at 200mm would give a different result vs. shooting at 42mm. From the same spot, you would have a tighter image, the perspective (camera to subject distance) does not change. So if the subject was the sail boat, you would have a tighter crop of the boat and it would fill the frame a bit more. At longer focal lengths, the depth of field gets shallower.

The following is not my image but represents my point.



Looking at the DOF scale on the older 28-50mm Nikkor push pull zoom, at a given focal length, you can see the color coded aperture markings correlate with the curve marking on the DOF scale. Pushing or pulling the zoom ring across the zoom range, shows the Depth of Field in the resulting image. Longer focal lengths have less DoF vs. shorter focal lengths at the same aperture. (I wish lenses still had DoF scales.)

Changing perspective (camera to subject distance), also changes the relative size of near and far objects in the scene. Perspective is controlled by camera to subject distance, not focal length.

A longer focal length lens, taking a picture of a far subject will introduce the compression into an image. Also called the 'telephoto effect' it makes the image appear crowded.

Hope this helped and didn't add to any confusion. (Gonna try and shoot a little today, been busy with work and life. )

This is in the macro range (close focus) and is similar to the assignment, though DoF is much shallower when close focused you can see more detail as the aperture is stopped down. Images were taken wide open then in 1-stop intervals.

Have a few more shallow depth of field examples.

We had our first provincial rc car racing championship event yesterday and I thought I'd play with the camera and take a couple of shots.


24mm, f4, 1/100, ISO100


45mm, f5.3, 1/500, ISO320


52mm, f6.3, 1/4000, ISO3200

(the exposure settings were experiments to see what I would get at different ISO)

Here is an example of using a small aperture with a long focal length to achieve sharp focus on the most of the flower but a nice soft bokeh for the background. This keeps the background from distracting from the main subject. Notice when keeping most of the flower in focus and completely blurring the background, it almost gives it a 3-D look.

For this shot I used a Nikkor 25-105MM on the Macro setting. F11 - 105mm - ISO 100 - Shutter Speed 1/250

Thanks everyone! John, that lens is not a dedicated macro, it has a macro feature that works pretty well. The lens was the consumer lens to have when we were shooting film. It is a 28-105mm and you can still find used ones around.

With those temperatures, do like I did and cheat! That one came from my archives, LOL

great shot Jerry! very cool how you were able to use such a small Aperture and still have the bokeh effect..nice DOF! i tried something similar a while back, but i was now where near f/11, more so like f/4.5 @ 300mm.

18-55mm @18mm, f/3.5, 1/320, iso 400, handheld

18-55mm @18mm, f/5.6, 1/125, iso 400, handheld

18-55mm @18mm, f/8, 1/60, iso 400, handheld

18-55mm @18mm, f/22, 1/8, isp 400, handheld

Well, I can see the differences between DOF in each. A couple things I noticed. I had to leave the focal length at 18mm to be able to use f/3.5. If I zoomed in a little closer, the smallest available aperature was f/5.6
Also, I changed my AF area mode to single point or else the camera kept picking different places to focus. I hope I was correct in doing so. All shots were handheld.
I guess I'm surprised at the f/22, 1/8 sec. Slow shutter speed & yet it seemed so bright in that room in the natural daylight.

That was one of the goals for the assignment! Congrats!

I didn't want to tell people how to set up the shots, though I listed what I did. I want you to get comfortable on how your camera works and how and when to change a setting...I changed my AF area mode to single point or else the camera kept picking different places to focus. In my flower shots above, I used a Manual Focus, once I figured out what I wanted to remain in focus, I kept it there by switching to MF. Now DoF changed while the same subject (hopefully) stayed sharp.

Slow shutter speed & yet it seemed so bright... Keeping the same ISO and stopping down the aperture allows less light for the sensor (or film plane) to capture resulting in a longer shutter speed. Remember you should be seeing equivalent exposures in all your shots.

Increasing (or decreasing) ISO can also change the shutter speed allowing for easier (or harder) hand holding, with the risk of a potential reduction in image quality. But that will be another assignment...

Edit: on the change in aperture as you zoomed. Variable aperture zooms change the maximum aperture as you zoom through the range with wider focal lengths having bigger apertures vs longer focal lengths.
This keeps costs down as it is less expensive to design and produce a variable aperture zoom vs. a fixed aperture zoom. Most variable aperture zooms are "slow" offering dimmer viewfinder images; slower AF in dim/low light situations and of course, the lack of subject isolation at wider apertures. Prime (single focal length lenses) and pro zooms are "fast" with apertures of f/1.4, f/1.8, f/2 or f/2.8 for primes and f/2.8 for zooms. These lenses typically cost more, weigh more and have larger front elements (meaning bigger and more expensive filters) can be harder to shade and keep flare down, but offer brighter viewfinders, faster/more reliable AF in lower light and better subject isolation. But again...another subject for discussion.

**I didn't want to tell people how to set up the shots, though I listed what I did. I want you to get comfortable on how your camera works and how and when to change a setting...I changed my AF area mode to single point or else the camera kept picking different places to focus.**

Thankfully, before this assignment I had started reading a guide to the Nikon D5100. Otherwise I probably would have no idea that I should have been changing settings, I would have put it in Aperature mode on the dial & that would have been it.

**Slow shutter speed & yet it seemed so bright... Keeping the same ISO and stopping down the aperture allows less light for the sensor (or film plane) to capture resulting in a longer shutter speed. Remember you should be seeing equivalent exposures in all your shots.
**

That's why I left the ISO alone. It got me thinking though, if you need a fairly deep DOF, seems like flash will be used most of the time indoors.

**I used a Manual Focus, once I figured out what I wanted to remain in focus, I kept it there by switching to MF. Now DoF changed while the same subject (hopefully) stayed sharp.**

Can you explain that a little more.

How are you getting the italics to "quote". Can't figure that one out.

Hi Tracy.

Regarding your comment below:

"It got me thinking though, if
you need a fairly deep DOF, seems like flash will be used most
of the time indoors."

...not at all. With a steady tripod you can turn night into day and still get sharp images.
As an example all three of the shots in the sequence were taken at shutter speeds where handholding would have been pretty much impossible, even with VR enabled on the lens. Putting the camera on the tripod and shooting using the selftimer did the trick. No flash used.

To see details of the exposure details, click on the image for a bigger version.

Does it matter what your subject is? What if you are shooting a pet or people?

Are you asking if DoF matters if shooting pets or people?

It matters only to your vision.

Some people will want to have more in focus, others less. One thing with portrait photography is to have the eyes in focus, or at least the eye closest to the camera in focus. With groups, you will want more DoF to make sure everyone is in focus.

With some tele lenses, you may end up with too shallow DoF (ex. AF 85mm f/1.4D) if shot wide open.

Only as it relates to shutter speed. I was surprised how low the shutter speed was on the soup cans shot at f/22. It seemed to me that flash might need to be used indoors a lot then. Rob then replied by using a tripod it's not problem. But we used stationary objects..soup cans & a guitar.

The question about pets or people is more in regard to the slow shutter speed at f/22. Pets & people are not necessarily stationary. Even using a tripod if you want a deeper DOF, say a group of people in the living room...is flash a must then?

Assuming you're talking about people and pet portraits indoors ?(hopefully they aren't running rampant )

In that case with a slow shutter speed, you'll definitely get a blur if they move. Taking these kind of shots would require some sort of additional lighting, with flash being one option.

It's one of the things I am learning at the moment, but it's all a bit out of scope for this current assignment.

Maybe one of the future assignments we could look at exposure and what different settings of aperture and shutter speed do, and then further in the future look at an assignment involving flash as well.

Can you explain that a little more.


Depth of field typically extends from 1/3 infront of the subject to 2/3 behind the subject. By keeping the same focus plane, you should be able to see more in focus elements as you stop down the lens. Just see your pics.


How are you getting the italics to "quote". Can't figure that one out.

See the HTML Reference on the left margin; you'll see it when you hit Reply. Remember, we use square brackets; when creating hot linked text, you want to remove the "http://" because the "link:" takes it's place. When you've done it a few times, it becomes second nature.

I understand the DOF 1/3 in front 2/3 in back. You seem to make a distinction between the Autofocus & Manual focus feature on the lens. That by switching it from Auto to Manual (I'm assuming you mean that button on the lens itself) that it changed the DOF in some way.

Hi Tracy.

If I may offer an answer.
Switching to manual focusing once you have a subject in focus (specially with macro) is a way to ensure the camera doesn't try to focus on another point when you press the shutter release again.

So basically, you focus on the point you want to and then switch to manual to ensure the lens doesn't move. The 1/3 to 2/3 split still applies to the depth of field.

Even with landscape photography, you can focus on something about 1/3 of the way into the frame and switch to manual focus to ensure the focus point/plane doesn't change.

Hope that helps.

Rob

>I understand the DOF 1/3 in front 2/3 in back.

Keep in mind the 1/3 front 2/3 back is only valid at a limited subject distance range (approximately 1/3 the Hyperfocal distance I believe).

Close focus distances the distribution is approximately 1/2 & 1/2 and past 1/3 the Hyperfocus the rear side grows sort of exponentially reaching a 1% front 99% rear.

You seem to make a distinction between the Autofocus & Manual focus feature on the lens. That by switching it from Auto to Manual (I'm assuming you mean that button on the lens itself) that it changed the DOF in some way.

I switch AF/MF on my body, but you can also do it with your lens if so equipped. My lenses are old and only my Micro has that switch. What I did not want to happen is for the AF to turn on by accident and change my focus point.

My cameras (D700 and F100) are set up so that I have AF controlled by the AF ON button at the rear of the camera. AF will only work if I depress the AF ON button; 1/2-way depressing the shutter release only turns on my meter. But to be safe, I still switch the focus mode selector on the camera body.

By using a tripod, fixed camera to subject distance and manual focus, I eliminated the variables that may effect the final image. The only changes came from (1) what the meter read and (2) the DoF due to the change in aperture.

Hmm a thought, for me anyway I always think of DOF to keep my subject in focus with varying amounts of background on or out of focus. Blurred background being bohkeh. Right? What if, keep in mind I haven't tried this yet, I want a good focus on my subject but I want everything in front blurred but from the subject back in focus. Is there a process for that?

Bokeh is a Japanese term translated as "out of focus highlights." This quality is dependant on the lens and the aperture blades, quantity and shape. Some lenses have harsh bokeh, the AF 105mm f/2.8D Micro Nikkor is one such lens. Some lenses have excellent bokeh and are legendary for their performance: AIS 105mm f/2.5 Nikkor (a manual focus lens).

What if, keep in mind I haven't tried this yet, I want a good focus on my subject but I want everything in front blurred but from the subject back in focus. Is there a process for that?

Well, there's a lens actually two for that - the Defocus Control lenses: AF 105mm f/2D DC Nikkor; Af 135mm f/2D DC Nikkor.

Here is my first ever attempt at doing depth of field. I have a few pictures that I created using Hot Wheels for my subject. The lighting I used was light coming in from a window on a cloudy day. I didn't do any adjustments to the photos because I wanted to keep them as I shot them for the assignment.

All pictures were taken using my D5200 with 18-55mm lens.


In this picture the focus was on the red car in the middle. I wanted to see what it would look like focusing in the middle and what kind of effect it would have.

Focal Length: 18 mm
Aperture: f/4.5
Shutter Speed: 1/5 sec
ISO 100


In this picture I focused on the black car.

Focal Length: 18 mm
Aperture: f/3.5
Shutter Speed: 1/6 sec
ISO 100


This picture I focused on the red car on the end to hopefully achieve the depth of field.

Focal Length: 18 mm
Aperture: f/4.5
Shutter Speed: 1/6 sec
ISO 100


This picture I focused on the front wheel to see if I could achieve a depth of field with one object.

Focal Length: 35 mm
Aperture: f/5.0
Shutter Speed: 1/5 sec
ISO 100

You may have to click on the pictures to see the bigger version, I cropped to keep the size down and get rid of a bunch of "junk" in the background.

Any comments, critiques and/or suggestions would be greatly appreciated.

Nice shots, James. I like to keep my images down to 1000 pixels on my gallery just so I don't have to scroll too much to see the whole thing - my preference.

(I was going to shoot my kid's cars, if I could only find out where they are hiding...)

Those came out perfectly fine, even with the kit lens. Nice show of shallow depth of field.

Part two would be to try close the aperture and see whether you can get everything into focus

Not sure if I did this right but here is my attempt to get them all in focus. The lighting isn't the best but hopefully it works.



Focal Length: 35mm
Aperture: f/11
Shutter Speed: 1/10
ISO 100

They may not all be in focus, but the depth of field is greater than the first ones, so you got it.

February is over, I hope it's OK to post this. This is my first post with images using my first digital camera that I got only 10 days ago - it took some time for me to figure this out

This is an example of how depth of field changes with aperture. The subject is the keyboard on one of my laptop computers focused on the central letters of the "home row" (F, G, H, J).

Camera: D600 on tripod
ISO: 1250
Lens: Tamron Adaptall2 SP 90mm f/2.5 macro (an old manual focus lens)
Lighting: incandescent flood lamps in my family room

Click on images for larger view.

No, I didn't convert to monochrome - the laptop is all various shades of grey.

f/2.8 at 1/20s - DOF barely encompasses the letters of the home row. Surrounding rows are barely legible.


f/5.6 at 1/6s - DOF is wider, covering most of the home row key, letters of the surrounding rows are readable but still fuzzy.


f/11 at 1/1.3s - DOF is wider still, all of the letters and numbers are legible, the function keys are starting to come in to focus


f/22 at 4s - DOF is even wider, all of the keys are legible. But it still doesn't really cover the entire depth of the keyboard. I could have stopped down to f/32, but at this shooting angle I would probably need a tilt/shift lens to render every key sharp.



Best regards,
-Ron

Perhaps I am a bit late to the party here, but I took the following shot about a week after I got my D600 and think it fits in with this category.

I was visiting Lafayette, IN, and was wandering around town after dark with my new D600 and a 50mm f/1.8 lens. I ran across this bar and took a couple of exterior shots, then went inside for a burger and a beer. The burger was tremendous, and the beer was very good.

I wanted to try out my camera in low light and was inspired by the beer, so I told the bartender the concept for my shot and he gave me the go ahead. I shot at ISO 800, 1/13 second at F/1.8. I wanted to see how the camera performed in low light, and wanted to get a shallow depth of field that would give me a sharp beer glass, but put the bartender pouring another round slightly out of focus.

After reviewing the shot at home, I think I should have stopped down just a bit to bring more definition into the bartender's arm and the beer that is being poured. I did not change the white balance to tungsten because a wanted a warm tone to complement the copper bar top and the glass of beer.

Nice idea. I agree that more definition in the background may have made a better shot, but this still clearly shows the concept of shallow depth of field.

Hi!

I bought an AF-D 50/1.8 lens just after Nikon announced the AF-S version. The "older" one was so cheap that my reasoning was I did not need the AF-S (on my D700), and that if even I moved to a body that did not have a screwdriver motor I then would be able to buy another 50...

Here is the first shot I took with the 50, and I think it shows well what a shallow dof is



I had crossed the street, literally, and was sitting with the then-latest copy of the French Chasseur d'Images. Note that they were testing the X100 then, which I have bought since...

D700, 50/1.8 AF-D, ISO 200, f/8, 1/1000 in aperture priority mode, which I use over 90% of the time...

I like it. I have a shallow DOF to add here in a bit when Inget to my computer. Earlier I had asked about getting the blur I front and behind and I think I succeeded! I was hesitant to add to this since it was anfebruary assignment but when Inthink about it I wonder if it shouldn't just be assignment one. There will always be new people. Oming in and it is a good place to start. Just a though.

I have here a stay kitten we took in. Yea cats seem to find me. I guess I am just a cat guy.
Anyway I like the bohkeh in front and back and a nice depth of field to call focus to the cat. I think. I apologize for the lateness of the post, a lot of work and waiting on a new computer put me behind.




I think if I had more separation from the cat post to the book shelf behind I could have achieved more bohkeh hiding the bookshelf a bit better but I was happy with this.

Here's my Februsry assignment submission. I know it's just a little late, but I just got the camera and the weather in my area has not been very cooperative these past few weeks. Nikkor AF-S 17-55mm f/2.8, 1/800, AP.

It's not quite as crisp as I would have liked and there is a little color distortion along a coupleof the leaves (from the movement?), but the day was rather breezy and I had to time the shot between gusts as best as I could....lol!

Nice job despite the wind and shows off the concept.

If you did want to stop the motion and couldn't get a higher shutter speed, turning the ISO higher would have helped as well. It would have given you a higher shutter speed at the same aperture which would have frozen the movement.

Thanks for the tip and encouragement, Rob.

I've heard so much about shooting with the lowest ISO possible to minimize noise, that I may have allowed myself to get a little gun shy. In hindsight, I see where I chould have either overridden the camera's settings or switched from AP to another mode and taken more control of the shutter as you suggested--

In all honesty though, in the heat of the moment, I didn't even think of those things even though the concepts are not foreign to me.... So much to incorporate and learn.... I will certainly play with it more to become much more familiar with with how each setting interracts with the other.

Again, thanks!!
