Hello, I am new to this forum butr have been using Rawtherapee for some time. I have been pretty happy using it to process my Infrared photo and have some pp3 files for one click processing which generally turns out well. I have been using the OMD M10 ii and considering the price point and tiny form factor, its a very good piece of equipment. I recently move to the OM3 as I faced various limitations when I started to do deep sky object photography. When I used the pp3 files on IR photos taken by the OM3, the color is totally off. I also try manually adjusting to create new pp3 files but so far have not managed to create the same results as I would with photos taken by the OMD M10 ii. Any one have done IR processing on photos taken by OM3 ? Both cameras was unmodified and I use the same 680 and 720 nm filters and same lens. So I guess it must be the sensors, maybe the Stacked BSI work differently ?
Hi and welcome! I don’t use RawTherapee but I do take IR photos.
Are you certain both cameras are unmodified? Usually cameras need to be converted for IR unless you’re doing really long exposures.
It might be helpful to share a RAW file from each camera if you’re able to. Just make sure to include a CC license statement. I know there’s at least one other person here who does IR stuff.
Yes both are unmodified and I just use 620 nm and 720 nm filters and do channel swap on the desktop. The end result is somewhat unpredictable as some turns out to be good while others are crappy. I need to use higher ISO and shoot wide open as I take photos handheld so need to keep shutter faater than 1/4 sec.
Here’s one of the result as I usually do not keep the RAW file afterward I am done with the editing. Its a bit stupid as I cannot go back to adjust anymore.
Here’s the ORF and processed jpeg taken by the OMD M10 ii

And here’s the ORF and processed jpeg using the same pp3

My guess is that the urban scene used a red/green swap and the nature scene used a red/blue swap.
In darktable, things look normal when processed the same (sorry I dont use RT)
Hello… I’m a newbie too… I mainly use RT, but have dipped my toe (actually it seems like a pair of winter mittens the way my processing goes) into DT. Currently RT is my way, but I’m trying to learn new stuff, hence dipping into DT.
Anyway, only ever undertaken UV work using microscopes… (looking for binding of chemicals to biological samples with excitation peak around 350-380 nm and an emission peak around 430-475 nm) so no use whatsoever for your request… but Hello! and your photos look really interesting.
OK, I created a DCP and went out during noon time to capture the most infrared and managed to create this
then I asled AI to create a photo for me and this is what I get in 15 mins of work vs 2 days 
Thanks for sharing the images!
I don’t use RT much, but in darktable I got this rather quickly - just auto white balanced in color calibration than used a second instance to swap the R and B channels.
I like it… where did you get your filters?
