It's been about 18 years, but I did well selling hand-colored black and white portraits. I found a market because it was a unique product (shot on either 4x5 or with my RB). It was mostly kids, so I would do the shoot in their homes, toting a little 400WS Speedotron with 3 heads. No special backgrounds (sometimes just a bed sheet from their home). I was upfront about the cost (minimum $1250) and prints were expensive. I think it was $80 for a 5x7 matted to 8x10. $150 for an 8x10. $200 for an 11x14. $300 for a 16x20, and $475 for a 20x24. I didn't have a sitting fee, but required a $625 deposit on arrival. I had very few who placed orders for the minimum. Most were around $1750. When I invested the marketing time, I averaged about one booking per week. A night of film processing, one day for printing, two-three days for coloring and matting. So, a job took up the better part of 4-6 days. It was fun. I do think someone could still do it today, and make money.
