I've never been one for PP, rather get it right in-camera.
But I was reading this this morning, so now i'm re-scanning some B+W negatives I've shot recently, and sharpening them up.

I suppose it's the best I can do until that new firmware is realeased, my 7D is obsolete without it, it's being used as a door-stop until I can get my hands on this new firmware...
