I acquired an ancient camera by most standards which says KODAK in fancy lettering and uses 122 postcard roll film. As I didn't happen to have any I stuck some fuji crystal archive color paper cut down to 4x5 inches. It definitely works and I've figured the ASA of the paper to be ~~8. I now have a problem because all my negatives have a reddish to magenta cast and all my prints are coming out cyan until I cancel that out and am left with an almost monotone print that looks ugly. I want to filter in camera so to cancel out a cyan print cast, I would use a red filter? Red filters out cyan light...but if it increases red percentage it would increase the cyan in the negative, which you increase the magenta and yellow in the final print evening it all out, in theory. For magenta I would need green? I need some help because every time I work through the logic I get a different answer:confused:. Has anyone had experience with exposing this in camera? I've just always gotten my base values and printed, though come to think of it it's always been a reddish light when the values are set. The paper is blue to cyan in color before processing... I understand reciprocity can be an issue when exposing at "fast" speeds like 1/25 of a second. Since the camera has 25,50,100 and bulb I am going to end up shooting 1/25 a lot of the time so I don't have to go beyond 2 seconds to where I can accurately time the exposures off hand. Can anyone fill me in the reciprocity? I heard that it's fine between 3-30 seconds, but what will happen? Specifically color shift. Attached is an inverted neg scan. Notice there is red in the tail light.
