About the Image(s)

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.

Wonderful image, focus, detail, no hot spot, pleasing composition & post processing - love it! Congrats!

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

Jeff I love your wonderful photo but even after reading your explanation I am still not sure how you got there. I love the soft peach color of the final image. A suggestion would have been to have had the lower flower not touching the stem of the flower to its left and placed higher in the photo somewhat like in my revision.   Posted: 12/17/2019 21:23:01

Nice move Jim. Can you share you you moved the stem?   Posted: 12/18/2019 09:07:41

Judy, my revision is not perfect but let me explain what I did in Photo Shop (I don't know or use Lightroom). First I used Photo Shop's selection tools (you know dancing ants) to outline just the lower flower and stem. The selection was not perfect because part of the lower flower crosses the stem of the middle flower so I could select the lower flower only up to the point of the stem of the middle flower. Then I used the move tool and the rotation tool (in EDIT) to move the lower flower to the place I wanted. Then I used the clone tool to fill in the empty space left when I moved the flower. Then, I used the selection tool to outline the missing lower portion of the stem which I then filled with a color which matched the stem color of the original stem. I hope my explanation is not too confusing but the key is learning how to use the selection tools.

Thank you for the explanation, this has been a good example of how adding details to the capture, editing, and suggestions really makes the PSA DD groups awesome!   Posted: 12/26/2019 12:44:12

I agree about the touching stems, great job showing what you were thinking (and later explaining it) -- thanks!!   Posted: 12/26/2019 12:44:47



 
Thanks so very very much Jim. Will give it a go!

Merry Christmas Everyone!   Posted: 12/22/2019 17:18:19
