I have a black and white picture taken around the 1930's of my grandfather which I would like to edit, the picture is probably a copy of a copy so it's pretty grainy and a lot of detail has been lost already not to mention that a past family member also used a pen/marker to highlight some details at one point in time. Can anyone recommend a photo editing program that I can use to improve the picture details/quality and possibly even try to convert it to color? Will something like Adobe Photoshop Elements 6 do the trick? Tried using iPhoto but there isn't really that much options to play with for what I am looking for. Any suggestions are greatly appreciated.
