Nikon D7000 IR converted to 590nm
ISO 100, 135mm, f/36, 1/13th second
I shot this image a little different than normal. I had some conversations with the tech support folks at LifePixel about setting white balance in the camera. They said that it is very problematic to set a proper in camera white balance with a Nikon camera converted to 590nm. They were not surprised that I could not get the camera to set the internal white balance. I also said that I was trying to set exposure using the red channel of the histogram on the camera LCD but was always underexposing the image. The histogram looked correct but the image, when brought into Nikon NX-D was always underexposed. They again said this was normal and suggested that I set my camera on B&W and then use the histogram. The image will appear B&W on the LCD and when I bring it into NX-D I can just change the view setting back to color. This worked really well!
Here is the processing steps that I went through....it may seem complicated but it really was not.
I set the camera to b&w mode
I metered the image and used the histogram to set the exposure. The image on the camera LCD was b&w which was fine.
I brought the image into Nikon NX-D and did two things...first, I set the image to standard color mode which gave me the red looking image as you would expect. I then did a white balance correction using a gray card reference from a different image I shot earlier.
I saved that image and then brought it into Photoshop to do a channel swap.
I saved that image and brought it into Luminar 4 for final post processing. I was playing with ON1 last month and this month I wanted to play with Luminar 4.

When you set white balance in NX-D were you able to get it below 2000? I find I'm often in the 800's.
I'll have to see if my a7r IR camera has a B&W mode; that's a neat trick! Am sure it help with focusing a lot. It was suggested to me when shooting IR to bracket - a lot - like 5-7 images! Which increased my success with exposure.
It sure is a drag learning and fumbling around with all the different software: for you NX-D, PS, L4; for me Capture 1, LR, and PS. Think I will look into Cl IR; it sounds like it might streamline the whole process.
Love the peachy stem/flower color!   Posted: 12/12/2019 19:42:50
