Holly,
I was kinda hoping someone else would reply. But I guess I'm it.
No recent experience, but I have done this in the past and plan to get back to it someday.
My best advice is to get a Marshall Photo Oil kit and follow the instructions. ( on the inside of the lid ). 15 yrs ago thats how I learned. There were not many people doing it even then.
You will need a print, on real paper, with a matt finish. Most paper is resin coated and will not absorb the paint. If all you have is a glossy print, you can spray it with re-touchers spray, if you can find it. You will also need to spray clear varnish on the oils when you are completely done. Until that time you can remove or change anything, and the print can be smugged.
There is also a brand of pencils, can't think of the name,but the oils are better.
I have also used water color pens. The cheap kind you buy at Wal-Mart. I have been very surprised at how well those images have held up over the years.
I will attach the one image that I have scanned. If I can get a chance later this week I will scan in some more.
Ideas.
Over the years I have seen lots of stuff hand colored. There was a Photog selling B&W Sepias of Texas landscapes with the bluebonnets that were hand colored. Awesome images.
Let me know what your thinking, and I will try to help you out if I can.
The way I have always looked at stuff like this is just jump in and go, all you can do is screw up your own stuff, and that ain't that bad.
