photo quality is probably based more on what kind of camera you have than what uploading does to the photo
but try saving the file or taking the photo at the largest file size possible?
i use jpg if that helps-
Thanks for the tip! My photos are quite high quality on iPhoto and I export them at the highest quality setting into Photoshop however I was resizing them to somewhere in the 600 pixel range… so Ill try uploading them at their original size.posted over 4 years ago
