I've spent the couple of weeks or so scanning and cropping photos from an old family trip album from 1988. They were taken with my father's Pentax MG SLR. Some are dark/grainy, some are washed out/overexposed, some have scratches and dust, some have faded over time, some were written on the back which has bled through, plus the cheap cotton gloves I initially wore to "protect" the prints seem to have left lint on some of the prints.

So far I've pulled them into Picasa and geo-tagged them where possible. I'm of two minds whether or not to post-process the photos to fix up the colours, remove scratches etc. In a way the faults in the photos add character to the images, and I was primarily scanning them to have a digital copy in case something happens to the originals. However having nice clean versions, with adjusted levels etc would be nice as well.

So what do you guys think? Better to leave them unaltered to fix the flaws?
