This problem may be painfully elementary to most people, but I am in a quandary as to the solution. I have been trying to use Polaroid color material in my 4x5 pinhole and have gotten only yellow/green and majenta/purple images. Does anyone have a suggestion as to what kind of filtration I must use, if any, to rectify the situation? It is all daylight material. I have used the Fuji material and it is perfect! What's the deal?!
