PURPOSE:To attain suitable color correction to the state of an external light in photography by providing an incidence angle setting means for making external light in a larger area than a picture area including a subject on an imprinting optical path for color tone correction. CONSTITUTION:A shutter blade 3 operates to open a main aperture part (a) and a film 4 begins to be exposed; and a subordinate aperture part (b) also begins to be open almost in synchronism with the operation of the shutter blade and the film 4 begins to be exposed outside the picture through light guides 5 and 6. A photometry part judges that the specific quantity of exposure is obtained, and the shutter blade 3 is closed to close the aperture parts (a) and (b). The tip 5a of the light guide 5 is nearly spherical and contains an angle theta1 of photographic view to enable light with a larger angle theta2 to be inci dent, and information is fetched in synchronism with photography, so the color of subject lighting is known accurately under all photographic conditions. Fur ther, the quantity of exposure of a color information fetch part is only set equal to the quantity of exposure of a photographic picture under general photo graphic conditions.
