I apologize for the ignorance, but I've gotta ask....

When I open a picture for post process, and I use the "save as" feature, I realize that the picture will degrade a bit.

But does the original picture that I've opened degrade as well? I'm using "save as" not "save", so I thought that the original will remain unharmed.

Thanks for taking the time....

Cheers!

Anytime you edit a photo, you can have a little degradation from both the editing process, and JPEG Compression (if you are using JPEG). You can minimize this by keeping JPEG Quality set to it's highest level in your editor (or save in another format like TIFF). Personally, I keep everything in JPEG.

Also, always start out with the original image (or a copy of the original image) whenever you decide to do something different with a photo. Then, try to make all of your edits at the same time (cropping, color corrections, resizing, etc.) before saving it again -- never overwriting the original image. In other words, don't start out with something that's already been edited (unless you have no other choice).

Right, if you open an image, but don't save over it again, then it will remain unchanged. But, just to be safe, I personally like to have my originals kept in a separate location, then start out with copies (so that I don't accidently overwrite the originals).

I NEVER save anything in .jpg format.



I always choose a lossless compression, such as .tif or .psd (Photoshop)

Yes, when having a "work in progress" you should save in an uncompressed format, or a format that saves things like masks and layers (like Photoshop's native format).

Of course if your final file has to be JPEG, then save it as a JEPG then.

BTW, I recommend making a copy of your photo BEFORE you start editing it; one day you will forget to do a save-as and lose your original. I keep one directory for originals (backed up of course), and another for working copies...if a picture I want to work on isn't in the working copy directory, I don't even load it into the photo program until it is.

p.s. There are no dumb questions...the only dumb one is the one not asked, and an unrecoverable mistake is made!
