Another way to modify images during capture is to use filters.
Another way to modify images during capture is to use filters. Black & white film photography and filters are joined at the hip. Most mono films are over-sensitive to blue light: a nicely lit scene on a sunny day will come out blank and lack detail in the sky space. A coloured filter to reduce the amount of blue light reaching the film will rectify this. A yellow filter has the weakest effect, orange is stronger and red is even more potent.
