Just a further thought Nicole, about slide films and film formats. I collected a couple of rolls of Velvia 100 120 yesterday, and a roll of the same film in 35mm, many of the shots were taken in the the same lighting at the same exposure for comparison, on projecting them I saw something I had known for years, the tonality, colour saturation and placticity of the image on roll film is far better than 35 mm, and as far as digital is concerned. forget it. I was seriously thinking last night of selling all my Canon gear and giving up 35 mm, try it sometime. I only have Mamiya TLR stuff, projected 6x6 slides with your Hassy should blow your sox off.
Best Wishes. Ben
