pretty much, that's it ...
emulsion to emulsion
heavy glass on top (or in contact frame)
expose to light process like you would any other print.
you could also make cyanotypes, and use the sun instead of an enlarger.
the only processing is wash/rise with water
and if you want to remove the blue, bleaching back with sodium carbonate ( washing soda )
and toning in tea or coffee or ???
oh i forgot the most important part ... have fun !
