"Capture NX and Infrared Processing"


Crestwood, US
          

After I got my IR-converted camera back I googled long and hard to find a workflow that would mimic the Blue-Green channel swap one can easily accomplish with Photoshop's channel mixer. There is no channel mixer on Capture NX 2.0, so I wondered how it might be done.

First of all, I love Capture NX 2.0. It is the best way to work with Nikon's RAW files (NEF). I use Capture NX 2.0 for all my processing and only go to PS CS3 if I need to do pixel editing (cloning, etc.).

So is there a way to process infrared NEFs with Capture NX? Yes, there is. I'm not going to tell you how to do all of the processing. Just the part that relates to images captured with your IR-converted camera. I have Nikon D70s with an "enhanced color" IR conversion from LifePixel. But what I outline here applies just as well to standard IR conversions as well. Here it is:

1. In the "Develop" section of your "Edit List" tool bar on the right, open "camera settings" and set your white balance. I do it with "set grey point" and use the marquee tool. Find the "green foliage" part of your image and set that as your grey point.

2. While in the "Camera Settings" go to "Picture Control" and chose "Vivid."

3. Then click the "Advanced" toggle just below "Picture Control," go to the "Saturation" slider and drag it all the way up to "9."

4. Now, here's the cool part. Click on the "New Step" button. Select "Color" and then "LCH" from the pull down menus.

5. Click on the pull down menu that says "Master Lightness" and choose "Hue." That will bring up a colored hue box. Below the box there's another pull down menu. Click that and select 180. Notice that the hues have all slanted.

6. Go to the triangular slider on the right side of the box. Slide it about two-thirds of the way up until the red and blue channels are switched. Watch your image. You'll want to experiment with the best place to put that slider. The red sky has now become blue.

7. Once you've done this you can tweak the image any way you want with black and white points, more color points, curve adjustments, black and white conversion, etc.

Hope this helps!

Great write-up! As I told you before, that bit about the LCH editor was the final key for me. I think you nailed everything and I'm happy to have one less thing I have to do the convoluted way in gimp.

Thanks, Klaus. I hope it helps.

The only caveat I might add is that using "picture control" for "vivid" and ratchetting the saturation all the way up to nine (steps # 2 and 3) are, of course, optional. They work for me on most images. But I'm not sure if that has anything to do with my "color enhanced" IR conversion or not.

Jeff,


I was following your steps with my newly converted D200 IR camera and I am not really seeing the wonderful conversion of my image. I wonder if anyone has any suggestions.

Perhaps I will try to see what I get when I use my older D70 standard conversion camera and see if I have any better success with your method.

Thanks for any help or suggestions.

Ilene,

Looking at this image I would say that the original exposure probably has some issues. That being said, I'm not suggesting that once you go through the steps I have outlined you will have perfect images. You may still have to do some lighting, contrast, and color adjustments. I always do.

Thanks Jeff for your feedback. I have uploaded the original file as well as a black and white converted file for the same image. I think the original file looks fine. If you don't perhaps I am having issues with my newly converted camera.

It looks as if you don't have your white balance set right when you are taking your IR pictures. I too have a D200 IR converted camera which you will find out isn't the best Nikon to convert.

You need to manually set your white balance before taking your IR pictures. You won't have to "convert" to B&W if it's set correctly.

I will look more closely at that but I thought it looked good. Why do you not like the D200 IR Conversion? Which cameras do you like?

Other people's thoughts on camera conversions?

It's not that I don't like my D200 IR but even Lifepixel will tell you it's not the best camera to convert. I had an extra (was my backup) D200 so I had it done.

You should point your camera at grass and set the white balance manually. It will get rid of the red tint and you won't have to do anything to get the B&W. Here's one.

I thought that with enhanced color IR cameras you need to swap channels. Is yours a deep B&W? Interesting about Life Pixel. I did not see or hear anything but positive about D200 conversions. Does anyone else have input on the pros and cons of D200 conversions? Also what is the best cameras to convert to IR particularly enhanced color? Thanks,

There weren't all the different options for converting when I had mine done. Mine is full B&W (deep B&W IR). You can go to www.lifepixel.com, they have a lot of information on their site.

From what I have read and have been told the Nikon D70 (maybe D70s) is the best camera to convert.

Hi Jeff,
Thanks for the info, Can't wait to give it a try.

Ilene, I was told by Daniel at Lifepixel that the D200 was one of the best for conversions because of the noise ratio in the D70. I know you have converted both. With the super IR conversion, it's all about setting the custom WB. I use a digital gray card, works like magic.

Now that I am using a green card for custom white balance before sshooting at different light conditions, my results have greatly imporved. I prefer the D200 over the D70 because it has nicer images and now the white balance issue is no longer a concern.

I need to comment on this even though it is an old post. There may be some advantages to converting a D70, but I can't support the D70 over a D200.

The D200 is the camera of choice for most professionals - Tony Sweet and Vincent Versace for starters. The reason is the more robust camera body, larger number of pixels in the image, type of sensor, and wider range of controls.

The D300 has pluses and minuses. Live View can be a huge advantage. But the sensor is viewed as being less responsive to IR than the older model sensor. The D700 is also a good option but I only know of one person who has a converted D700. I think the jury is still out but will ultimately view these cameras positively because of Live View and low noise.

Jeff,
I had a hard time at first following your process, but then this evening I got it to work. I suspect that it doesn't work quite4 as well as the PS color mixer, but then it doesn't cost $600+

The "from" condition:



to the "now" condition:



What do you think?

Well I've made a lot of progress since I posted the above images. Not only have I learned the process that Jeff explained, but I'd like to add a couple steps to the process.

After the color/LHC/Hue/180 and sliding the color slider, I would add altering the brightness/contrast as a "new step" as well as increasing the focus detail by invoking the unsharp mask (another "new step"). With the unsharp mask, I have had the best luck with intensity set to about 45-50, radius at about 20-25 and leaving the threshold where it is.

Here are some results of this processing.

Pre PP:



After PP:

Hi Tom,

Instead of Unsharp Mask, you might want to try this "clarity" step.

High Pass filter. radius 20. Opacity, Luminance 80 Chromanance 50. The exact values, especially the radius, will vary by picture size and personal taste.

Nice shot, btw.

Hi Jeff, I would appreciate your ideas on this:
The NX2 'channel swapping' process outlined above is not a red/blue swap, it is a hue adjustment which changes red, blue, and green simultaneously.

Here is an NX2 LCH Hue "channel swap" following what is outlined above:


Here is a red/blue channel swap using Photoshop:
Photoshop>Image>Adjustments>Channel Mixer
Red channel: Red = 0%, Green = 0%, Blue = +100%
Green channel: Red = 0%, Green = +100%, Blue = 0%
Blue channel: Red = +100%, Green = 0%, Blue = 0%


If anyone has any good way to process the image below using NX2 to match a red/blue channel swap using Photoshop please let me know.

Nano,
Those of us who have been using the NX2 process that Jeff described, have known that it isn't a true channel swap as it is in PS, but it is the simplest (onliest? ) way to adjust a NEF. I don't know all the details of PS but as I recall you can't open a NEF directly into PS without going through ACR first.

The question I have is whether the translation to an intermediate format or JPG by ACR compromises the channel swapping process in any way.

And a follow-on question - what about other raw formats? I don't like working in jpg (and don't know about the psd format) because of the slight loss of control. I recently starting shooting IR with an Olympus and their raw files ("ORF") can't be used in NX2, but I prefer NX2 over other tools.

I believe if you saved the file as a tiff that you could then do a channel swap in photoshop without compromise.

Yes, 16 bit tiff works great for that.

Some may not know. I didn't know. Results are not the same.
