I do not understand why my Canon RAW .cr2 files will not open in Rawtherapee. Here is a screen capture of what I see in Rawtehrapee, 4.2.936 on my Windows 7 (32-bit) computer:
The raw file is IMG_2636.cr2. What I see is a black box. The small image at the upper right is the JPEG which was shot together with the raw file. They both open in Canon’s Digital Photo Professional. but I can not open the raw .cr2 file in Rawtherapee. Is there something in settings that is not set correctly?
As @Jacal said: RT 4.2.936 does not support the raw files from your camera.
You have to use a more recent version of rt (e.g. the one @gaaned92 linked in the Issue I mentioned above) to open your raw files in rt. Simple, isn’t it?
I spent a lot of time to speed up rt not only for 64 bit cpu. But don’t try noise reduction or wavelets on 36 mp (or larger) raw files using win32 version of rt
Actually it is NOT simple as you did not send me the URL to download Rawtherapee version 4.2.1074. I do not see this listed at: http://rawtherapee.com/downloads
Where do I get the correct version?
That download page needs revision as 4.2.936 does not work correctly with 32-bit Windows OS of XP and above.
Well, now I had to try. After some fiddling (noise reduction, wavelets, as you proposed) with a 36 mp NEF file, RT crashed, and it wasn’t able to open a 50 mp CR2. Still, with my 18 mp files, it works better than it should dare.
The host win7 computer is four years old, with an i5 processor and 16 GB of memory. They don’t get old as fast as they used to. And, of course, congratulations for your optimizations!
Thanks. But before I download and install Rawtherapee, will it work with raw files for both my Canon G16 and Canon Rebel SL1 or only the G16? I do extensive post-processing on my images, but when I bring up an image in Canon’s Digital Photo Professional shot simultaneously in Raw and JPEG I see no difference in either the appearance or histogram. I know there are more bits in the raw file, but my eye can’t see the difference.
I went to: https://drive.google.com/drive/folders/0B2q9OrgyDEfPOEZmVlBzLWlnSWc
Then clicked on the 6th item from the left (last one on top row) and saw a listing of 4 items. However, when I click on the .exe or any other file nothing happens. So how do I download Rawtherapee 4.2.1074, master ?
