I have bought a box of Ilford Orto Plus 5X4 which I intend to experiment with for general outdoor photography, mainly landscapes and seascapes. One problem I am having is working through the physics of which filters I should use, given the different colour sensitivity of the ortho emulsion. Can anyone advise me? Also, should I be using the same filter factors as for panchromatic film?
