I have a Canon Rebel SL3 that I’ve been using to take photos, and I get an error when trying to upload my images to imageJ. Could this be because the RAW photos save as .cr3 extension rather than .arw? If so, is there any way I could safely convert the photos to .arw or get imageJ to accept the .cr3 file?
Ahh – that’s a really new camera model, so it’s possible the DCRAW version used by the toolbox can’t handle it. I’ll try to update it and release a fix.
