Sigma 50-500mm f/4.0-6.3 EX DG HSM for Canon EOS

I was making some adjustments to a picture in PS and stupidly saved the changes to the memory card which wrote over the original picture. It appears to have erased the EXIF data. Is there any way to recover the original picture on the memory card with the EXIF data?

I don't find that PS erases the Exif data on my images. Did you try opening the image again in PS to see if it held the information? I assume you have closed PS and found this out much later otherwise you go just step back everything you did and it should be there also.

if you had just deleted the info maybe, but I think overwriting is a completely different animal.

It depends on how the program "overwrote" did it actually delete the old file and then write a new one?

If the file is actually deleted, or just the pointer in the drive tables, and the new file placed in different bit locations, the old file may be sitting in un-located with the 1's and 0'1 still intact.

There are several programs out there that can recover deleted files, if the data was really directly over-written, you're SOL.

Then you should put it back on your computer it might read it there, because PS doesn't remove the Exif normally

Thanks for the help Mike but the problem is that the changed image is now saved to the memory card and appears to have overwritten the original image. If I were to try to send this to DPC to validate the picture they would not get the original image and it would be disqualified :( I tried closing PS and bringing the picture back up from the memory card and it loads the changed stored image.

Was it jpeg image ? if yes then PS will overwrite the file and you will lose the 'originality'

Sorry it didn't work, for you, any file I change and alter in PS still hold the Exif data on the new altered image except when I use save for web.

NEVER edit files directly on the cf card. Copy them to a folder to work on, don't format the CF card until you're done editing.
