I had an April show of silver gelatine enlargements and was asked to show my new work in Pt/Pd. I am somewhat reluctant. I have never been really pleased with the way Pt/Pd shows behind glass. Or at least how mine look. Has anyone shown prints mounted and framed without glass? I don't have so much worry about the fingerprint touches but I would not be allowed to pin the mounted prints right to the wall. They would have to hang from clips on a rail ten feet up. Any advice on display sans glass?
