Printing out calotypes
I have a nagging feeling this is a stupid question. But here it is.
Everything I've read and experienced has suggested that for salt prints and other silver chloride printing out processes, a negative with plenty of contrast is desirable.
Here's where I get confused. I've seen many of pictures of calotype negatives, posted online and in Alan Greene's book. They don't look particularly contrasty. In fact a lot of them look to my eye slightly flat. Yet these were used for printing out, and still are.
What am I missing? Am I just wrong and not seeing the contrast in the negatives ( maybe because of the color? )
