"studio lighting and noise"


Niagara-on-the-Lake, CA
          

I was trying to shoot some orchids with my studio lights and when I put them on the computer they seems to have a lot of noise and the clarity wasn't what I expected

I have an old set of braun 600w lights and was using the modelling light to take this image. I was trying various light locations but for this shot I had two lights with umbrella's stations about 4 feet on the left and right side at about 45 degrees from the camera

when I zoom into the photo there a lot of noise and very little detail. Am I doing something wrong or is this because of the lights I am using

Nikon D300s
Nikkor 70-200mm f/2.8
1/6 at f/18 ISO 200

focus was on the flower on the right side

Are you sure this is not a DOF issue?

Closeups have a very small DOF

Or a diffraction issue?

Fstops greater than f11 can have diffraction caused by the small lens opening.

It looks like the EXIF data about the lens, focus distance, fstop were removed. With EXIF Tool you can see the DOF for the shot.

thanks George
I never even realized I had the meta data turned off. This image should have the data attached

I was about 5' away and according to my DOF calc I should have had a DOF of about 1.5". I even used the Live View setting to focus on the flower

It looks to me that you might be getting some camera motion blur. What type of tripod were you using? Were you using mirror-up? Was there any breeze that could have moved the flowers in the 1/6th second the shutter was open?

Also, you will get sharper results with any lens if you do not stop it down quite so far. You were at f/16 with your 70-200mm, and that lens is slightly sharper from f/4 to f/11.

And, you were at 200mm. That lens is slightly sharper if you stay off the max and min zoom settings. Try 180mm.

As far as the noise goes; was the image exposed properly? Did you brighten it in post processing? If you did, that always adds noise. Make sure to expose to the right on the histogram to minimize noise. You can always darken it later, and that will not add noise.

thanks for the suggestions Russ
I was using f/16 with my 70-200 on a Gitzo 3541 XLS with WH-200 Wimberley Head. I did use mirror lock up with a cable remote. This was shot in a dark garage with just the lights. I don't think I had to change much in the exposure in Lightroom but will cheque. I redo the shot again using f/11 and see how it goes. Perhaps I will also shoot it during the day with sunlight to see what I get

thanks again

Dave

Did you turn VR off on your tripod?
