That's a fantastic link and it really gives a person a good idea of what went into taking a simple photograph back then. Wow, That is definately more involved than I thought it was. I think you're right, after seeing that, Photoshop is a piece of cake.
Looks as if you not only had to be a good photographer back then but a mechanical engineer and chemical engineer as well as an artist. Kind of puts a whole new appreciation on their finished work.
Thanks Jim, that was very enlightening.
