Hi, Im looking to see if anyone has some advice on where i can get my hands on color reciprocity failure for long exposures. I shoot night photography and I've been shooting and have got down a pretty good system. Yet since i shoot analouge and meter with a digital camera, i do not really know if my exposures are accurate because i have nothing to compare to.
So, does anyone have any recommendations on color reciprocity failure chart for long exposures (30 sec.-4hrs)? Thanks
