This is a higher-contrast copy of the original photo. (My grandfather is the guy seated on the far right.) Painting skin color would be tricky in any case, but man... these guys are brothers, and they're all different shades. All of them except my grandfather were long dead by the time I was born. So I'm kinda guessing what their skin tones were like in real life.I mixed Transparent Red Iron Oxide (Golden) with Burnt Umber (DecoArt Americana) as his basic color, then mixed in a little Warm White (Americana) for the highlights. The shadows are Ultramarine Blue (Golden) blended with the basic color mix, to produce a muddied shade. It looked a little stark, so I washed it with the basic mix and that seemed to smooth things out.
Oh yeah -- the hair on both men was a wash of Burnt Umber and Lamp (Black) Ebony (Americana).
Not worried about the little bleed-over spots; I'm going to mess with this a little more. Then I'm going to scan the final piece and put it into a genealogy photo album.
Hey, does anyone know a way to scan something that has a transparency in it? Or do you really just need to photograph it at the appropriate angle with the right lighting? Thoughts?
