ABSTRACT:
A method and apparatus for effecting photometry in an automatic exposure camera includes the provision of photometric means which determines the brightness of an image field. Upon depression of an operating button, photometry is successively made of the brightness of an object being photographed, utilizing the photometric means, and corresponding photometric values are derived. Each successive value generated replaces the value previously generated. The last value generated is stored for subsequent use upon release of the operating button.
