hmmm, i guess i was calling blue sensitive "ortho" without realizing there was a difference ....
so does this mean that photo paper is "ortho" and sensitive to green
as well as blue, or is it only blue sensitive or something different altogether ?
early photographic processes that just use silver nitrate ( like wet plate, dry plate ( some ) &C
would they be considered something else besides "orthochromatic"
thanks in advance !
