I have a few questions regarding paper negatives.

What I shall use them for
My intension was to expose onto the paper rather than use film on my 5x4 camera.
I will then develop, scan them and post process in Photoshop

Why not just use film?
Paper seems cheaper
Paper may give me a different look

Why not contact print them
No real room for a dark room at the moment

Questions:

Paper to buy ?: I am looking at Ilford Multigrade IV Deluxe Glossy although not keen on glossy. Is RC paper better than FB paper ?

Developing: Can I develop the sheets in the SP-445 tank like I do my film ?
