55451888Exposure determining. This instrument consists of a slide rule, two scales of which are fixed and the other two movable. The fixed scales are subdivided with divisions corresponding to the logarithms of numbers which indicate according to suitable units, one the intensity of light for the day, and the other the "inertia" or inverse of the sensitiveness of the given plate. The movable scales are subdivided with divisions corresponding to logarithms of numbers which indicate according to suitable units, one the speed of the lens, and the other the length of the exposure. The length of exposure will thus be equal to the intensity of the light multiplied by the speed of the lens and divided by the "inertia" of the plate. This can be shown by the ordinary manipulation of the slide-rule.

4755901937Smethurst High-Light Meter. In order to judge a photographic exposure in accordance with the "high lights" of the scene, the light incident upon it is measured by pointing towards the illuminant, from a position adjacent to the scene, an exposure meter which includes in front of the light sensitive element a translucent plate made of a substantially perfect light diffuser such as opal glass. A lens, stop, or filter may be introduced between the diffusing screen and light-sensitive element, or the diffusing screen itself may be tinted. The function of the diffusing screen is to integrate the light falling on it from different directions and the screen will, for the purpose set forth, be flat and unobstructed on the side on which the incident light falls.

4975171938Film advance mechanism and automatic film loading. For roll-film cameras, a feeler detects the ridge where the film joins the backing paper, this causes a lever to rock and engage the film measuring roller and locking cam. The film is advanced by a lever attached to a large pinion this in turn drives the take-up spool. Pressed against the film on the take-up spool is a measuring roller which is tuned by friction with the spool. The measuring roller connects via a spindle to gearing which rotates a cam having notches mapping the movement of the film (i.e. amount to wind before the first exposure is reached and length of frame). A pawl acts on the cam and engages a notch when the correct amount of film has been wound, the other end of the pawl engages the pinion to which the film advance lever is attached. Reversing the film advance lever frees up the pawl. As the measuring roller is in contact with the film itself allowance is made for its increasing diameter. Related patents are: BP 499544/1939, BP 495276/1938, BP 431982/1935, BP 426915/1935.
