I took some photos with my iPhone 4 (yes, a dinosaur). I wish to enter them in a contest. The instructions say they must be no smaller than 400x400 px and no larger than 600x600 px. I have no clue! How can I tell? And, is there some way I can adjust the resolution once I download the files onto my PC? Please advise…
FYI: Under my iPhone settings, under “Photos & Camera”, I do not see an option to select the picture resolution. Is there some industry standard default resolution used by iPhones, perhaps?
