re: "original, work edits, compression, data loss,..." The whole exhaustive rundown is this: Most low-end cameras are only going to give you jpg coming out (and into the computer). TIFF is nice if you can get it. RAW is nice if the other components in your system support it. If you don't get those options, then JPG can work fine, and hopefully you're using the highest quality setting (less compression) option available. Often, where you do have a choice, it will be JPG and TIFF, or JPG and RAW. TIFF is a nice lossless that goes into PShop well. RAW is proprietary (Canon RAW vs. anybody else's RAW), your other system components may not always support it. Always take the lossless option if it's availabe (and if it actually works). Otherwise, just go JPG with the highest quality setting (using more MB of storage, but nobody rides for free <gg>) If you're using PShop, then your first post-edit save should automatically go into .PSD format (Photoshop Native). Or you can use "Save As" just to be safe. (I noticed you were using PShop from the other thread). Do all your work in this format. (TIFF, whilst non-lossy, doesn't provide layer support. JPG is both lossy and no layer support. RAW will probably not save that way anyhow, defaulting to PSD on fist save). When it comes to output — specifically where Michal and I were referring to our "3-8" conversation, that's where other conversions come into play. We were talking about high resolution magazine reproductions, and whether one should use certain settings (1-12, 3-8) for certain types of print work. Standard prints for Mum & family are much less critical. As always, your mileage may vary. <g> That should be the exhaustive end all of options. Unless cameras start doing PNG and PICT, too (Oy) -MrB

Do you use TIFF for the Original and through all the Edits then, and only then Save to a jpeg for distribution? Bill, who knows magnitudes more about Photoshop than I do, put it all down much better than I ever could: #reply-18800355 My cameras can save in RAW plus JPEG (compression of my choice, I pick the least amount of compression). I mostly work with the mildly compressed original JPEG files unless the image is problematic and needs serious work (exposure, color balance way off) that can be fixed better in RAW. In either case once imported into Photoshop I convert to a PSD (Photoshop Native) and work in it until I am done. Then I convert the result to TIFF for high end reproduction (posters billboards), and JPEG for email distribution to newspapers and magazines. I sure like your work. Thanks!!!
