I recently got on ancestry.com and traced back my ancestors for several generations. In the process several old photos of photos showed up, some very blurry pictures of 1840's photo technology. I can barely see my GGGG Grandmother and do not see much other than shadows. A few others are clearer but could use cleaning up. I have heard of photoshop, it is really worth it and can I do old photo restores from it? how about colorizing? can B&W photos be converted to color?
