Flipping a JPEG without quality loss?

SiD the Turtle · 17 Apr 2010 at 12:06

So my dad has been scanning in thousands of negatives only to find when we loaded them on the PC, that they're all back to front.

Of course I could program a very simple macro in PS to open each image, flip it and save it but each time you save a JPEG you introduce another iteration of quality loss.

Anyone know of a quick and easy way to flip these JPEGs without losing the quality when re-saving?

Turn the monitor sideways

Save them at quality level 12. I'd be amazed if theres a difference.

Must you save the result as JPEG? You could flip it in software then save the result in a lossless format.

You're only choice is to flip and then save them again. If they're were saved at high quality in the first place then the quality loss will be minimal.

When you save again, save as PNG or TIF to prevent loss.

That looks good. Nice find.

No need for unnecessary space usage with lossless.

Bingo, cheers for that, my Google-fu was weak!

Cheers for all the other advice guys, I could have saved to PNG or similar to keep everything, but I though, the interweb being the interweb, someone out there would have already encountered this requirement!

Doubt you would have posted this if you already had this expensive software

But adobe fireworks batch process is very good for this, saved my ass many times.

Put all the files in the list, choose the commands and it will whip out all the images in seconds.

It's patularly good for reducing those large 4MB pictures, into web friendly sizes.. 800px width, 100Kb etc.

Saves you a lot of time uploading pics on facebook.
