I did a portrait job of all the family members of a family that could afford it on 8x10 printed in platinum. The Parents are pretty old, the kids being grown and on their own. I shot them individually on 8x10 with a very sharp lens and when I looked at the silver RC proofs I thought, no way. Too harsh and wrinkly, the old mom will never like it. When I printed them on platinum though, the loss of resolution you get from the solution soaking into the paper fibers was the perfect softener. Both the mom and the dad got smoothed just enough to make them look really good and they absolutely loved the prints.
Even if you were happy to print in silver though, shooting portraits LF is difficult and expensive.
