Colors change on export to JPG
Hello,
I did some simple alterations (straighten and autocrop) to an image from a 35mm scan saved in JPG with a sRGB IEC61966-2.1 color profile. When I export the altered image to JPG, the color is not the same anymore. The dark greenish tones become more like red or brown. Given that I use mac (OS 10.11.6), I have tried to do the following: preferences>color management>mode of operation>no color management, and everything else set to "none", but it doesn't help. The file open behavior is set to "ask what to do", but it doesn't ask anything upon opening the original image. Does anyone know why it happens and how to preserve the original colors when exporting to the same format?
