Unsharpening an image

[Adamphotoman]

Have you overwritten the card?
There are some programs to get back deleted files as long as you have not reformatted or over written too many times.

As a memory device to help remember in the future, it's called "unsharp mask" because it masks out the unsharp stuff. More or less accurate in both film and digital worlds.

Try this if you have Photoshop

1: Copy image to new layer (be sure to stay on this new layer for the rest)
2: Filters > Other > High Pass
2a: Set pixel ratio to 1.5
2b: press OK button
3: Image > Adjustments > Invert
4: Set the layer type to Overlay

If the dis-sharpening is not quite right, back up (control-z thrice) to 2 and try a different pixel ratio. Repeat as necessary.
