Editing Infrared Images with Photoshop CC

Thank you for your reply.

I had set the camera for a DNG Image and put it on Bulb Mode.  Using a Tripod and a remote shutter, I opened the shutter for 30 sec. I'll try it on Camera Raw.

Are you shooting RAW  (.NEF) or JPG? The Blue channel of the image you posted has no values more than 32, and is very noisy (as the Blue channel often is). I don't see any obvious JPG artifacts, so I'm guessing RAW?  I tried adding a Levels adjustment, to bring all three channels to full range, and then swapped the Red and Blue channels. I got something that looked closer to some of the examples I see on the Web, but that noisy Blue channel really gets in the way.

The tutorials I've read mention adjusting the white balance in Camera Raw, and then opening in Photoshop and mixing the channels there. It looks to me like you haven't done this. If you haven't give that a try.

Another thing you could try is increasing your exposure, to get more information in the Blue channel. I used to do this with daylight negative film shot under Tungsten light (without an 80A filter), to bring the Yellow layer(the layer sensitive to Blue light) up out of the Toe of the characteristic curve, so all three layers (C, M, and Y) would have similar contrast. Just be sure you don't up the exposureto the point where the Red channel starts clipping.
