So here’s the problem. I managed to delete a photo from my digital camera. Now I need it back. I recovered the file, but strangely, it’s not actually recovered.

Now, I know file recovery is hit and miss, and since this was a photo from the camera itself (not a memory card), things get more complicated. Anyway, I manged to get back the photo…sort of.

The file I now have is 160×120, instead of the 3040×2288 it should be. Now, if this was an actual thumbnail, I would expect the file size to be pretty small. Instead, this little 160×120 image is 2.16MB. This leads me to belive that somehow I can get the real photo (or at least something better than the little image) back from the file. There has to be a reason for that much extra data, right?

Does anybody know how to do this? I figured Photoshop might have some advanced sort of raw file reading or some sort of rebuilding/recovery. Alternatively, someone could point me to a good recovery program (or even some other way to do this).

If it helps, the camera that the file came from is an HP Photosmart M627.

I wouldn’t mess with it any more and instead call hp as soon as their tech support opens monday. it does SOUNDS as like there might be something usable there, maybe they can help.

It’s probably just the memory footprint. Since Flash memory can only be overwritten a few thousand times before breaking up, the algorithms will always try to write new images into a new empty section before starting to overwrite others. The previous state of the memory cells will thus be visible for a long time, but may not necessarily contain any usable data. It may be possible to retrieve the data, but this may require some severe hacking, so as David said, wait for HP support to give you proper directions.
