So many ways to process 720nm IR image

IR images are known to produce interesting B&W images and also pseudo color images. I will show some examples.

This series shows how the look can vary based upon how you process it. And this is only a taste. This could run in even more directions. And remember the color images are pseudo color images. Essentially just B&W images in which coloring is added.

As someone who occasionally dabbles in IR (590nm filter on converted Canon P&S), I’m really enjoying this post. I’m constantly considering IR image processing options starting with the “white balance” selection spot. And since I own most of the same software, I’m off to the races. Thanks for the “sharing” post!

If you have a dedicated 590nm filter, you can still and a 720nm or longer to the camera and get those looks too. That is provided that your point and shoot can accept external filters.

The way the rule works is that if the camera is dedicated 720nm, you can't go shorter to 590nm, but you can go longer.

Have fun. The range of IR looks you can produce is endless.

For the benefit of those not used to seeing IR images, I have added several for you to see.



Using a 590nm, the colors will be more intense, but you can selectively desaturate them to taste.

Does your point and shoot support RAW files? RAW files work much better for IR processing.

Yes, it’s a tiny Canon S100. It has a little bit of flare issue but avoidable depending on the sun location. I usually shoot RAW and JPEG. I’m thinking about converting a Canon G16 this year via LifePixel.

These are really nice. I have an outdated Nikon D300 that I've often thought about converting. You are pushing me towards making that move.

Consider using https://www.isaacszabo.com/infrared.html. He is cheaper. I have had 9 done by him with excellent results.

Thanks for this link. Wow, 9 camera conversions! What models did you have converted? All have Live View? What filter did you go with? What lenses are you using? Sorry for all the questions, but I am seriously thinking about converting my old Nikon D300.

I have 2 IR converted cameras. First one was an old Sony A55. Produces great results, but the autofocus is off with IR images. This is a SLR type camera and the camera uses light reflected by the translucent mirror to do its focus rather than the sensor, and since IR focuses differently than visible light, AF is off a bit. The solution is to do manual focusing.

Second camera is a mirrorless Olympus EM5ii. No IR focus issues at all. This camera has taken over completely and is an absolute joy to use for IR images.

Both cameras were done as full spectrum which means that I have to use external screw on filters. And I do have filters in different sizes for different lenses. I can also use a UV-IR cut filter and revert the camera back to visible light if I want to. This works perfectly and I can't see any difference in results compared to a non-modified camera. Also have a UV-IR cut filter that broadens the red end to include the hydrogen alpha 656nm for astrophotography too.

I actually have a 3rd camera that can do IR. But this one has been converted to be a mono sensor by removal of the CFA as well as the IR filter (and moire filter too). This is a Sony A6300. And it has been a lot of fun doing mono IR. With a mono sensor, there is no need to do demosaicing and the results end up with improved detail that demosaicing would have compromised.

I mainly concentrated on Sony because I already had them and an array of lenses that I could use. I have had a Canon T1i w LV 650nm; Canon xTi no LV 850nm; Sony A350 w/LV 720nm; Sony A700 no LV 720nm; now for mirrorless, Sony NEX 5R LV no VF FS; 2 Sony NEX6 w LV and VF 720nm; 2 Sony NEX 7 w LV and VF 720nm; converted. Plus I have converted a number of point and shoots (13) to full spectrum IR myself. Additionally, I have 3 that I do the magnet hack on. I gifted several to a friend and family members. I need to seriously consider releasing some of the back into the "wild" of the camera world! lol

I stay away from Nikon because of the difficulty of white balance for me. All my cameras have the ability to set in camera White Balance instantly. Apologies for rambling. I was hooked from the start when suggested I get an Olympus C2100 UZ 2 megapixel camera and add a 720nm filter. 12 years later I am still hooked and the C2100 is still with me.
