Three stops, with different sized apertures, belong to each set of lenses. In dull weather, and in copying objects indffierently illuminated, the largest sized aperture stop is used; the middle sized stop is for general use in moderate light, and tire smallest size when the object to he copied is exposed to full sunshine, or when great sharpness is required ; and it may he taken as a general rule, that the smaller the aperture which admits the light, the greater is the sharpness of the pic¬ ture produced, but the time of exposure must be increased where such small apertures are employed. 20 Landscape Lenses.
