last question when printing a photo larger than a 8x10 I was told to use tiff instead of jpeg. would that be a setting on my computer for my cd for printing, or is tiff on my camera?i try to find tiff on my camera, I didnt see it. maybe I over or some looked it or something.

tiff is an uncompressed picture file type. You can save your image as tiff in PS, or whatever image program you are using. Some cameras offer tiff as a file type, but most don't, so it will probably be something you will have to do on your computer. Since jpeg is a compressed file type, meaning every time you save a jpeg, it will compress (lose) some data, it is generally considered better to do your image processing in tiff (though if you save your jpegs with the lowest compression, it takes a number of saves to have any noticeable lose). Did your print lab tell you to use tiff instead of jpeg for larger than 8x10 printing?

David is right Estella. TFF is a lossless file format, it does not compress when you save it, therefore you retain all of the data in your image. JPG will compress to various degress depending on what you select in the options dialog box. If you have images that you have already edited and saved in jpg with compression, then it would be a waste to resave them as TFF. The best way to take advantage of the lossless feature of TFF is to save your original as TFF from RAW. However, TFF files can get rather large, anywhere from 6 - 10 times the size of jpg, so you'll need additional storage capacity like an external hard drive. As far as answering your question TFF vs. jpg for larger prints, that I really don't know. It would seem to me that any file you send to the printer, would be converted to a format the printer understands, one of the reasons for a print driver. I don't know that it really matters to the printer what file type you are sending. It does matter when you edit or repeatedly open and save a file. The more you do this with a jpg, the more degradation your image suffers from. Sorry I couldn't be of more help.

Hello Estella, Bob is correct concerning opening, saving, opening, re-saving images...degradation will eventually occur, but I doubt you will notice it unless you go through perhaps 100 iterations. Your question is as complex as it is simple. One has to assume a few basic facts first. Final answer? Printing aside Estelle, always save your original immedietly..make a COPY of it and work on the COPY.
"If you have images that you have already edited and saved in jpg with compression, then it would be a waste to resave them as TFF." While you can not recapture image quality (data); saving from JPEG to a TIFF file will not cause as much subsequent harm when resaving since JPEG is far more aggressively compressing than TIFF upon each re-save. This has nothing to do with editing. All the best, Pete
