I’ve recently noticed that whenever I save an image as jpeg, pixel information will be written from the first to the third channel overlaying with what was in the third one.
Everything is fine if I save as either tiff or gif though. This becomes very obvious in 2 channel images that have been converted to RGB and the third channel is by definition black. Since this also overlays in 3 channel images and thus renders the information in the third channel partly useless, this is a massive issue for our image analysis.
This only happens when saving as jpeg in imagej/fiji. If I save the tiff version of the image as jpeg using photoshop this is also not the case.
Would anyone know why this is happening? And more importantly have any idea how to solve this issue? This suddenly started in ~February and was absolutely fine before that.

I’d be grateful for any help.
