I have been thinking about getting into large format for the purpose of contact printing lately. I like the idea of a print that is amazingly sharp and pretty much a 100% representation of the negative. However, I do like to work in color occasionally and I was wondering how feasible contact printing is in color. What equipment do I need to do it? Just an enlarger with a color head and contact printing frame? What paper is best to use for this purpose? RA4 or Ilfochrome?
