    When saving in TIFF format, I realize it is better for editing because you don't lose quality on each save. But are you suppose to use NO compression to conserve the lossless state of quality? Or is it okay to use compression? And which compression is best for size and quality?

    Thanks!!

    the higher the compression the worst is quality. no compression guarantee

    the higher the compression the worst the quality. only no compression guarantees loseless quylity. you gotta try some prefences to decide whats best for you.

    Hmmm I dont think this is right. You can compress data lossless (Winzip for example compresses data lossless). But I was wondering the same as themonko, if the offered compression methods when you save the TIFF are indeed lossless compressions.

    zip is something totally different. we speak about tiff, zip has to be uncompressed before you can read (open) it, tiff's are compressed and don't have to be uncompressed --> you will lose quality.

    One of the compression options you have is ZIP, one is JPEG and something else. Is the ZIP compression using the algorithm of the standard ZIP format or is it just called like that?

    well, I don't think so (but dunno). jpg2000 is pretty good, but I think ps doesn't support it.

    Can others edit my Photos:
    Photos OK to edit
    I always save my TIFFs as uncompressed. They are big files, but worth the image quality for me.

    LZW compression with tiffs is lossless, as well as zip. I use lzw compression, and it is readable by most software. Tiffs in general aren't widely accepted on PCs, but Adobe software, and most graphic software will have no problams, and most image viewers have no problem. Irfanview can display tiffs with layers as well.

    Looks like I wasn't the only one with the question. So to wrap-up, if I am going to compress, LZW or ZIP is the way to go.

    Thanks for all the feedback!!
