Thank you for this clarification. Based on your response I did a round-trip test of a PSD from desktop to ipad and back in 4096x4096 with one change, and this time it maintained the resolution. Can you clarify your comment about "zooming" as I'm unclear how the resolution of an uncropped image is changed from viewing it differently? I have always saved to PSD vs camera roll so perhaps this is how my first image was resized.
I'm glad to hear you will have full resolution saving to the camera roll-fantastic news. Can I suggest that the output resolution be displayed when a file is about to be saved so that it is clear if it has been changed?
Thanks for your reply and I look forward to seeing this product develop further.
