I have a client who would like to create a banner that is 6x5 feet. She supplied me with a very high quality photo that she'd like printed on the banner. Ideally, it would fill up most of the banner. The file size of the photo is 670 mb. In Photoshop's "Image Size" window, it says that it's 12960 x 8640 pixels, 36 x 24 inches, and 360 ppi.
Is there some way to make this photo display larger, short of taking a new photo with a higher resolution? Perhaps this is more of a photoshop question, but if anyone has some ideas, I'd love to hear them.
Thanks!
