I initially posted a thread on this in the iOS forum, but it didn't get any responses, so I thought this would be a better place for it, since my problem might be Adobe related. The short of it, since iOS 8.3 (8.4 didn't fix this), it's impossible for me to import any TIFF files to the Photos app. When I import the files, and open the Photos app, the thumbnail will look normal, but upon opening the picture, the picture will be pixelated. It will do this whether iCloud Photo Library is turned on or off. Initially, I thought this was an issue amongst all TIFF files that were imported into the Photos app. However, once I did some testing, I noticed that any TIFF files that were created, say, in the Preview app or any TIFF files I found on the web, did not have this problem. This only happens when I create the files in Photoshop. The files will pixelate, whether the TIFF file is compressed or not. I've read other people also having this problem, including with the Mac version of the Photos app, which I don't have access to. I'm using CS5, so I'm not sure if any other versions of Photoshop are doing this, and if anyone would be willing to try it out, that would be helpful, as I'd like to file a bug report with Apple, if necessary. My TIFF settings are LZW Compression, Interleaved Pixel Order, and set to IBM PC Byte order. I've played around with this, though, including turning off any compression, only for the same issues to occur. If there's any other issues I'm overlooking, feel free to let me know. It would be greatly appreciated. Thanks!
