TIFF with LZW compresion can be a middle ground of not the fastest or slowest saves, with some file size savings. Like a LOT longer than the other options. TIFF with ZIP compression can make the smallest files (using lossless compression) but ZIP can take a glacial amount of time to save. Photoshop and TIFF formats save faster than TIFF compressed, but the files are bigger. Photoshop PSD format saves faster if you disable its compression in Preferences, File Handling I think, but then the files are bigger. But there are many other tradeoffs you will deal with. But for the most part, I do flatten images once I'm done with them.Ĭorruption should not be a problem with any of the compression options. I do flatten images when I'm done editing them, so that does help save space (although I do generally keep a copy that's unflattened - with all layers and groups intact - just in case I need go back and do something later). Normally this wouldn't be an issue, but I'm finding I'm using PS more and thus ending up with PSD and TIFF documents and their sizes can add up pretty quickly with a lot of editing. (this may not be as big of a deal as I am making it perhaps since if I remember correctly, default settings for TIFF when saving does employ some level of compression unless you explicitly turn it off). Suggestions? I'm mainly just concerned about file corruption during compression/decompression. So I'm perhaps a bit old-fashioned (going back to the DOS days of file compression) and am still a bit skeptical of file compression in general, but when it comes to TIFF and file compression in Photoshop, is there a preferred compression format to use? Speed is not so much a concern, but size is (as I am usually blending multiple exposures from a 45MP camera which can lead to large Photoshop files I've found, most at least 400MB TIFFs without any compression).
