Hello All, I have two seperate questions. First, does anyone out there know the filer ring size for a Turner Reich convertable? It's the series 2, with an 18" and 12" focal length. I need to know so I can order a step up ring for my 67mm filters. Also, I am having a problem with these small white balls on my double weight contact prints(8x10). I never have it when I print with platinum or azo so it must have something to do with the double weight fb paper. I have tried thick glass and it still happens. Any recipes for success would be greatly appreciated.
many thanks eck
