    I shoot everything at jpeg. I was told everytime you open and close a jpegs it degrades a litle bit more. How many times can you look at a jpeg before you start to notice it degrading?

    Also do you save your files as Jpegs or tiffs. I've got a digital arts teacher who says we should save everything as tiffs. If I did that I would need three more hard drives. What are you guys doing?

    Yes you are correct and for that reason it is best not to save as a JPEG. Rather save a master as a TIFF or other non compression format. If you need a JPEG for e-mailing or web, do a save as from your master.

    How much can you open until you begin noticing degridation?

    opening and closing are different than saving something.

    for example, you open a file , rotate it and then save the rotation, which is a change. At that time the file re-arranges itself and re-compresses itself which over time is degrading.

    I use only raw files, change them to a TIff file if i am going to use it; and keep 4 copies of every file; the orginal and 3 back up copies. External Hard Drives are very cheap these days.

    So If i'm just opening them in preview then nothing happens? I actually need to make a change and save it and they will be compressed again? Am i getting that right?

    Yeah, it only compresses when you actually save it.

    I don't think most people are going to save it enough times to see a change though (maybe I'm wrong, but I've never noticed any quality loss).

    I keep all of my RAWs and process the ones I like into JPEGs. I used to use TIFFs, but like you said - I saw that it was going to use all of my disk space very fast.

    I save all images which I will be using for sale as TIFFs. Other images get saved as JPGs. You never know when a customer is going to come in and ask if you can make a print larger than what you have for sale, and with the TIFF, you have a better chance.

    How does a tiff allow you to print a larger image than a jpg? It's just an uncompressed version of the jpg. Still maintains the same dimensions.

    maybe I'm missing something.

    Only saving a jpg impacts quaility. And this is marginal. I would consider always making a copy of a jpeg to work on. Leaving your originals as is OR at least do a "save as" which would be the same thing.

    Check out the thread on jpeg compression that was recently posted. Youll see the true effects of JPEG compression. I see no reason to ever save as a jpeg unless your emailing the photo to someone. Also why would you shoot in jpeg if RAW is an option, makes no sense.

    File size. I don't have the money for multiple external hard drives.
