I was looking for information on saving a picture in a larger quality so that I can print a canvas photo in 16 x 20. I did what was advised above to Sally by changing my preferences to Archive, but now nothing in the photo editor works. As soon as I open the picture to edit it it zooms way in. I scroll out and the picture is there but none of the editing options change anything in the photo. I have an awesome family picture that I need to take a telephone pole out of using the cloning tool. It worked great before I changed to the archival mode. But I need the higher quality picture for my printing purposes.
