This is rather annoying, I have both Painter and Photoshop using the same colour settings. Both use RGB Adobe 1998, however photoshop always sees the image more saturated than what it actually is. Which isn't a huge deal since all I do is make an adjustment layer after but this problem hasn't happened before until recently. It's most likely Painter fucking with me since when I save the psd as an image from Painter the jpeg is also too saturated. It's rather annoying... I've really never had this issue before >.< - I don't have colour proofing on when I paint if that makes a difference. (not sure if it does - never have used it.)
