When I save my files as JPEG or PNG, it's much darker than it seems in photoshop?
how do I fix this problem?

is there anyway to make the bright settings or something in photoshop appear different than it really is ?

never heard of this problem before

Me neither..
It's like.. the picture in the photoshop document seems brighter, than it actually should be??

anyone have some sort of experience with this?

I had the same problem, only with sharpness but then I realized I didn't have contacts in.
Idk how you would fix it, never heard of it either, good luck though.

Step one: Google
Step two: take a screenshot of your JSP background and change your photoshop background (that surrounds your canvas) to the same color. you can alt click and copy the color code and then paste it in. (could be a contrast issue playing tricks on you)

i agree
