The origins of this is advice I attribute to Joseph Holmes (as in www.josephholmes.com
). That's where I first heard it:
You view your image in PS with a neutral grey/gray background to help ascertain colour/color casts (even ones you weren't aware of before...), and viewing it on the white
bg gives you a more accurate idea of the true contrast
of your image. (ie. viewing your pic on a black
bg on a monitor will always
make it look more fabulous and contrasty than it really is, and as a result your printed image will look washed out).
All assuming viewing a file on a calibrated monitor, etc. And
an Elektra Micro-Casa Leva coffee machine. As reliable as two sticks, they don't break down, and make unreal coffee. If you take the time to learn how to handle it... just like colour management and listening to Joseph Holmes. I wonder, how many colour-management fanatics are also coffee and coffee-machine fanatics...
For what it's worth,
