Thanks very much for your help and feedback Larry. So far I haven’t had any issues at all with jpegs, even as high as 4000 x 2160 resolution. And yes I did encounter exactly what you described at that resolution…moire patterns and sure enough yes it was easily solved by applying some gaussian blur. I’m very relieved to hear then that jpegs will be no problem. I also just discovered that Adobe Bridge does not allow me to store metadata for “gif” image files. Thank God I have very few gif images. I’ll be sure to convert them to png or tiff. I also see that in the latest version of Photoshop CC, when you save an image there is no “jpeg” option. A lot of other options though: PSD, tiff, png, BMP, even giff, but no jpeg option. Has jpeg been officially discontinued from photoshop as an image format? I thought gifs were an older format than jpegs.
