A photometering method in a photographic printer where color balance and density are adjusted by a color compensation filter and where a photoprint may be made by irradiating light on an original film through a mirror box, including the steps of: setting the color compensation filter to a photometering position so as to allow the light quantity per unit area of an image information detector including an image sensor to be within a predetermined area, photometering the original film with the image information detector, and then setting the color compensation filter to an exposure position for automatic photoprinting.
