What magazine companies uses Adobe InDesign and Photoshop for their designs?
I don't think that Adobe is going to give you a copy of their customer list
Contact the magazine(s) and ask
I mean...most of them?
It used to be Quark Xpress, but they dropped the ball big time and InDesign swooped in and was an amazing breath of fresh air and everybody dropped Quark like it was puppy poo.
But everybody has always used Photoshop since the beginning of time.
