I understand that every time you open a jpg file in photoshop and resave it as a jpg, you lose more and more data. But what about copying files? When I open a desktop folder and copy the jpegs from the folder to a CD, is there any loss of data? Or are the copied files identical to the originals?
Along the same lines, my current saving routine is:
* Upload images from card reader to a folder on the hard drive(images were taken as fine jpgs) * Save images to CD-R
* On working with an image, save as PSD or TIFF
Am I losing any data in this process, aside from the choice to use jpg over TIFF in the camera? Would I be saving any quality by immediately batch processing the images to TIFF format before saving to a CD?
Thanks.
