ABSTRACT:
When an unexposed filmstrip is advanced several frame widths in a camera to position the first available frame for exposure, a frame counter is changed from an original empty setting to a "1" setting. According to the invention, a visible indication is provided in response to the frame counter being changed to its "1" setting which confirms that the first frame is positioned for exposure. This is done to reassure the photographer that proper film winding and film initialization have occurred.
