I've been asked to make a 9 foot x 3 foot banner for a family business advertisement.
I got some details off the printers:
DPI Resolution is 300.
Format can be either EPS or a PDF would be fine.
The banner size is 9' x 3'. (feet)
So, my question here is what kind of size am I looking for in photoshop? I understand the higher the DPI the better quality, but I kinda need to know how to make the file in photoshop, because if I did exact measurements the file size is hugeee! I'm kind of aware that you can do any size if the DPI is high enough? Some elaboration would be good to know
