Photos taken are too big and dpi is too low
I took several photos with my new iPod Touch, sent them to my Mac, then imported them into Photoshop for editing. Each of them is 22" x 22" at 72 dpi. How do I set the iPod Touch to take smaller photos at a higher dpi?
iMac (20-inch Early 2008), OS X Yosemite (10.10.4)
