resizing recovery?

[tonybyrne]

I have accidentally resized my original files from 5616px to 450px.Is there a way to recover them to their original quality?This was carried out in CS4 through automate>batch.Any help would be greatly appreciated.Regards, Tony.

i don't think there is a way to recover your original file if that was the only file.
next time before doing anything to an original image opened in photoshop, duplicate the image and close the original and you can do whatever you want with the dupe while the original is intact.

Nope, you've thrown away information and you can't get it back. Well, unless - as edbayani said - you still have the original, or a backup. The CSI trick where you can zoom in infinitely and regain a huge amount of detail with some smart programming is, unfortunately, rubbish.

Well its already been said you cant get back original data but...

I know in the GIMP theres a liquid rescale plugin photoshop has something similar built around seam carving. You mark areas you want to stay proportioned and resize and it adds pixels everywhere else. How good it will be I dont know as its making calculated decisions based on an algorithm. The other option I believe the professionals use is a resynthersizer I know the GIMP has one I think it was from the GMIC people again it guesses the pixels but based on rules and takes a while lol.

One method will work better than the other and may enable you to resize your images to a printable size.

On a side note.... did you just right delete the files?? if you have the card there on and didnt format or only quick format you may still be able to recover them
