I learnt last night that apparently all photos etc should be saved as .tif files as .jpegs deteriorate with use or over time, and you can go back to a file and the pic aint there any more  eek


but I wouldn't have a clue as to the whys and wherefores of this

"Reloading in JPEG format is ok, the problem is when files are
re-*saved* in JPEG format.  Each time this is done, a file is
recompressed again, and more detail is lost.  That's why TIFF
format is recommended -- because it's a "lossless" format,
subsequent re-saves do not recompress a file, so there is no
loss in image quality."

It only matters if you're editing them lots, if you take it off the camera, do a single resize and never edit it again, it will be fine - keep the originals in a separate and you'll never need to worry
