Frank, I learned a lot from Barry Thornton's articles on developing etc....I think he is still using film but scanning/enlarging his negatives to larger sizes for contact printing. I just don't see how you can get fine prints from this "digital negative" process.
His motto used to be “You can’t make a fine print from a coarse negative”. Careful film testing, development and proper exposure was essential. The disturbing thing is that his new book implies that you can just "fix" the digital neg in photoshop, (provided you exposed properly to get enough information). I guess he is getting the results he wants. It just does not interest me.
At least he is not using digital cameras....
