A photographic camera in which at least one of the two main exposure factors (shutter speed and diaphragm aperture) may be set either manually or automatically. Indicating means is provided, visible in the viewfinder of the camera, to indicate to the user both the exposure factor value which he has set manually (if any) and the exposure factor value which the automatic mechanism would select according to prevailing light conditions, regardless of whether the user plans to utilize the automatic setting feature or whether he prefers to set the factor manually.
