In my first post here, I mentioned that I had just gotten a new (to me) IR camera to replace my converted Nikon D2X. Got a used Nikon 7100 from Lifepixel with their 665 enhanced color filter. This is my third IR camera, and all with that filter. Enhancing color is what I wanted to do from the beginning. I do the red/blue channel swap, and then in Hue/Saturation I go to each color and rev it up as much as I want. I try to get as many colors as I can in each shot, and it's amazing how many I can find. These are the ones I've finished so far.

Very interesting!!!

Be sure to try to "invert" also. And to try it over a range of Temperature offsets.

A couple examples:

Image 1 is a closeup of a dandilion using a 720nm filter, with the colors inverted with a -75K color offset.

Image 2 is a spot of ground hugging weeds using a 720nm filter and the colors inverted with no Temperature offset.

Image 3 is the same image as #2, except the Temp offset was changed.

Image 4 is a standrd image where with the Red-Blue swap, the sky would be blue and the leaves white. But instead, the RAW image was inverted at no Temp offset.

All kinds of ways to have fun here.

John, 10 photos are just too many for our reality minds to digest at one time. Like eating 10 delicious diferent flavored donuts at a time!!! It takes time to look at an individual photo and more deeply appreciate its beauty and envy a Bee's enhanced UV-wide spectra vision. I say UV because the colors are as tho they are what one would see with UV-sensitive eyes. UV fluorescence seen by bees has many colors we do not see.

For normal people who have stumbled into the IR section, there is a reference to explain:
https://www.lifepixel.com/infrared-photography-primer
For the filter John has:
https://www.lifepixel.com/infrared-photography-primer/ch4-internal-filters-for-modified-cameras-enhanced-color-infrared-filter
https://kolarivision.com/choosing-an-infrared-filter

My conversion is full spectra and I have a range of filters, but my favorite is yours, the 665 nm. "665nm is the sweet spot between 590nm and 720nm, producing vibrant false colors with a good black and white contrast."

This article tells about using the white-balance as an additional tool in IR photography. Thank you John for prompting me to look at the "enhanced" 665 to see if it is different that a normal 665nm... it isn't I gather.
White-Ballance is discussed by example photos:

Thanks. Enhanced Color is Lifelpixel's branding for their 665 filter. I was having trouble setting the white balance with the new camera, and Lifepixel told me Adobe isn't the best for setting IR WB, and suggested I use Nikon's free NX Studio software to set it with their eyedropper tool. Then I can try WB from various parts of the image to see what works best.

Rob Shea's free profiles actually shift the temperature far enough to actually do a white balance with Adobe. Once they are loaded, it is really, really easy to try out different settings.

Amazing results I have the 720nm, and it lacks a great deal other than for doing B&W, IMHO. As soon as I got it converted, I saw I should have gone full-spectrum so that I could have experimented with other filters and colors instead of predominantly magenta and cyan....

I knew from the start I wanted to do color IR, so I chose the Enhanced Color Filter. I don't care for the full spectrum idea as I don't want to have to buy and use filters on the lens. Having to view and shoot through a dark filter is a pain. If I had a mirrorless camera converted it would solve that problem, but I have had three old cameras converted and they weren't mirrorless. Besides, I find plenty of experimentation possible with that filter, and I like to have a consistent color palette so the images look like they belong together.
