I've done a short tutorial on re-processing images that have been shot in raw mode using the E-P1. It's possible to go back and correct an image that was shot with the wrong settings. Anything that was done to the image after the shutter closed can be changed: White balance, noise filtering, aspect ratio, art filters, saturation, sharpness, contrast, the black & white mode's colour filters, gradation, colour space and probably other things too. I hope it's useful. If it helps just one person fix a photo, it's worth it.
