all silver halide film respond to _ and _ but not to _, _, or _ unless they are specifically sensitized with dyes

green sensitive film, used in radiography

used in photography and sensitive to the entire visible light speturm

regular lighting (darkroom illumination)

safelight (darkroom illumination)

used during repairs, PMS, and cleaning

diffuse light, exposes the film, fog is increased

exposes or partially exposes the film, a gross, obvious artifact is produced

should have an electrical interlock that prevents it from being opened while the door to the darkroom is open

light used during processing

provide enough light to illuminate the darkroom while ensuring that the film remains unexposed

incandescent lamp with color filter

darkroom illumination considerations:

2-8 times more senstive to subsequent exposure than unexposed film

it contains the latent image

increase in sensitivity after exposure to white light or ionizing radiation

safelight filter for blue sensitive film

safelight filter for both green and blue sensistive film

safelight filter watts

safelight filter distance
