I need to make a 2ft x 6ft banner. and i was wondering what program should and setting and stuff like that i should use.
Depends if u can vector i would use Illistrator and make sections of it and piece them together at the end so the mbs isnt to big. Use photoshop for editing but mainly use Illistrator.
Photoshop is not recommended, unless you have a server farm for a computer, and you have at least a resolution of 2506x3200. I'd recommend Illustrator or CorelDraw, as said above, as they're vector applications.
