Hi, I've been shooting some constructed cameras that for all intensive purpouses are pinhole cameras. I have started using a regular pinhole camera with a 4x5 back and shooting both color positive and color negative film. I've developed them with c41 so they colors shift or they come out normally. The film I use is both old and new. My question arrived when I turned in some film, and all the film has orange casts to them. The ones with the most cast whch are almost completely orange/red. I have been scanning and editing the colors in photoshop but these past ones are beyond changing. Is my problem just the film or is it something else I am doing? The film with the most issue is with porta 100T film. I dont think its really an issue, the images came out very interesting. More a curiosity of the color shifts.
