- Description
- A General Electric Exposure Meter (type PR-3) in a black leather pouch. The meter has several dials on the front in order to set the exposure, a silver metal button on the left-hand side, a brief instruction plate attached to the back, and a black and gold fabric cord attached to the bottom. It is mostly made of black plastic - the dials on the front and instruction plate on the back are both metal. The leather pouch has a front flap that snaps closed at the bottom and is mostly open on the inside so as to access the meter’s dials - there are openings on the left-hand side and the bottom for the button and cord. In the bottom right corner of the front flap is an embossed gold crown.

- Description
- Hand held exposure/light meter made by Weston Electrical Instrument Company in a black metal finish housed in a brown leather case and a long black strap.In the top of the exposure meter there is a clear plastic covering. Along the very top there us the name of the manufacturer in white cursive lettering that reads “Weston Master II” and written underneath in capital letters “UNIVERSAL EXPOSURE METER.” Below this is the light scale where the value of the scene would be indicated. The scale contains the values “0” “25” “50” “100” “200” “400” “800” “1600,” which means that the two values on this instrument are calibrated 0-50 and 0-1600. (candles per square foot.)Below there is a circular face with several figures and a dial that turns/rotates. The outside row of figures on the exposure control dial represents the light value settings and corresponds to the light values on the light scale. Below the round dial there is a tiny circular button that is used to set the exposure control dial for film speed. As the dial turns it reveals the “EMULSION SPEED” with a red baize finish that has become worn throughout its life. The row of figures at the bottom of the top dial is the f/stop values and has an “f” to make this more apparent for the user. The row of figures directly below the f/stop settings are the shutter speeds. After setting the exposure control dial to the light value obtained on the light scale, any of the combinations of f/stop and shutter speed directly opposite each other are correct. On the rear of the meter there is a black plastic covering that contains several circular cut outs that are called a hir.ged baffle. This can be swung open (against the case) using the gold latch, which clips into a tiny hole or socket when the user wishes it to be closed. When opened the light sensitive photo cell is directly beneath this baffle and contains several protruding circles. When the baffle is open, the scale range is 0-50; when the baffle is closed, the scale range is 0-1600. Below there is an oval shaped face with extensive information that is held in place with two small screws on both the viewer left and right side. There is silver lettering on a black background that reads “WESTON ELEC. INST. CORP.” “NEWARK, N.J., U.S.A.” A silver backing separates the patent information and has black writing that reads “MODEL 735” on the viewer left side. On the viewer right side the number “7454510” is engraved. In the middle there is a gold-coloured screw with the words “ZERO CORRECTOR” written in black. Below this there is the patent information; “U.S. PATENTS” “2,274,441” “2,073,790” “2,346,555” “2,137,466” “2,463,770.” Below these numbers are the “FOREIGN PATENTS” “FRENCH 862,770” “BRITISH 531,996” “CAN. 347,085” “CAN. 411,975” At the very bottom underneath there is the manufacturer’s location; “MADE IN U.S.A”The brown leather case fits snuggly around the meter, with a metal clasp that allows both sides of the meter to be seen. On the front of the case in the top middle is a stamp that reads “SERVICE” and a simple illustration of a man walking with a rectangle. On the reverse side is a space for an identification card that is empty but has sections for name, address, and phone number.

- Hand held exposure/light meter made by Weston Electrical Instrument Company in a grey metal finish. Along both sides of the meter are a series of protruding lines that allow one to safely grip the object. At the bottom of the artifact there is a metal hook, which would have allowed a string to be attached like on the other Weston meter’s owned by Nicholas. There is also no longer a case to protect this particular object. In the top of the exposure meter there is a clear plastic covering. Along the very top there us the name of the manufacturer in white cursive lettering that reads “Weston Master II” and written underneath in capital letters “UNIVERSAL EXPOSURE METER.” Below this is the light scale where the value of the scene would be indicated.

- Description
- Hand held light meter in a pear shape with a stainless steel body and leather case. Along both sides of the meter are a series of protruding lines that allow one to safely grip the object. On the viewer right there is a pointer lock, which is locked when positioned upwards and released when positioned downward. At the bottom of the artifact there is a metal hook, which has a black string running through. In the top of the light meter there is clear plastic covering. Written in capital letters is “WESTON MATER IV” above the light scale. The lights scale contains the numbers “0” “25” “50” “100” “200” “400” “800” “1600,” which means that the 2 values calibrated on this instrument are 0-50 and 0-1600.Below there is another light scale in the form of a circular face with several figures and a dial that turns/rotates. The dial on the outside has a series of protruding lines to make movement easier and contains a row of figures. This dial controls the lens aperture (f/stop) scale and has a series of values representing the focal length of the lens; “1” “1.4” “2” “2.8” “4” “5.6”. On the same dial there is also the letters “EVS,” which stands for the exposure value setting with a cut out window that reveals the EVS values. Working in a clockwise direction (on the same dial) there is also the letters “U,” “A with “1/2” over top,” an enclosed arrow that is known as the normal arrow, a “C” with “2x” on top of it, and a “0”. As this dial is turned it reveals a partly red baize and black numbers on a silver background that represents the shutter speeds in fractions of seconds. The inside dial has a series of light scale values and an exposure index window that line up with the “U,” “A,” normal arrow, “C,” and “0.” On the opposite side of the exposure index window is the exposure index knob. On the rear of the meter there is a black plastic covering that contains several circular cut outs that are called a hir.ged baffle. This can be swung open (against the case) using the gold latch, which clips into a tiny hole or socket when the user wishes it to be closed. When opened the light sensitive photo cell is directly beneath this baffle and contains several protruding circles. When the baffle is open, the scale range is 0-50; when the baffle is closed, the scale range is 0-1600. Below there is an oval shaped face with extensive information that is held in place with two small screws on both the viewer left and right side. There is black lettering on a silver background that reads “UNIVERSAL EXPOSURE METER” “MODEL 745” SER.W” and “107522” engraved. Below the manufacturer information is listed; “DAYSTROM. INCORPORATED” “WESTON INSTRUMENTS DIVISION”. “NEWARK. N.J.. U.S.A.” In the middle there is a gold-coloured screw with the words “ZERO CORRECTOR” written in black. On the viewer left side of the zero corrector there is patent information; “U.S. PATENTS” “2463770” and on the viewer right side “FOREIGN PATS” “CAN. 411975”. At the very bottom on either side of a circular cut out are “ASA” and “K=1.0” written. Underneath “MADE IN JAPAN” has also been written.There is also a brown leather case with this object. The front has “WESTON” written in gold letters. On the viewer left there is a brown button that allows the case to be opened or fastened shut. The leather has been stitched together with light brown thread that is visible. The bottom of the case has an opening for the black string to be strung through so that the light meter and case are attached. On the rear there is a brown leather strap stitched.

- Description
- Hand held light meter in a pear shape with a stainless steel body and leather case. Along both sides of the meter are a series of protruding lines that allow one to safely grip the object. At the bottom of the artifact there is a metal hook, which has a red string running through.There is a clear plastic covering located at the top of the meter. Written in cursive letters is the company name “WESTON MATER II”. Underneath this written in capital letters is “UNIVERSAL EXPSOURE METER”. The light scale underneath contains the numbers “0” “25” “50” “100” “200” “400” “800” “1600,” which means that the 2 values calibrated on this instrument are 0-50 and 0-1600. Underneath the scale the word “Light” is present. Below there is another light scale in the form of a circular face with several figures and a dial that turns/rotates. The outside row of figures on the exposure control dial represents the light value settings and corresponds to the light values on the light scale at the top. The row of figures at the bottom of the top dial is the f/stop values and has an “f” to make this more apparent for the user.. On the same dial there is silver letters that have a line that correspond to the figures on the outside dial; “U,” “A with “1/2” underneath,” an arrow that is known as the normal arrow, a “C” with “2x” below it, and a “0”. As this dial is turned it reveals a partly red baize and the emulsion speed, which is self-evident as the words “EMULSION SPEED” are present. The row of figures directly below the f/stop settings are the shutter speeds. The outside row of figures is the light values, which is apparent as the word “LIGHT” with an arrow points to these values. After setting the exposure control dial to the light value obtained on the light scale, any of the combinations of f/stop and shutter speed directly opposite each other are correct. Below the round dial there is a tiny circular button that is used to set the exposure control dial for film speed.On the rear of the meter there is a black plastic covering that contains several circular cut outs that are called a hir.ged baffle. This can be swung open (against the case) using the gold latch, which clips into a tiny hole or socket when the user wishes it to be closed. When opened the light sensitive photo cell is directly beneath this baffle and contains several protruding circles. When the baffle is open, the scale range is 0-50; when the baffle is closed, the scale range is 0-1600. Below there is an oval shaped face with extensive information that is held in place with two small screws on both the viewer left and right side. There is silver lettering on a black background that reads “WESTON ELEC. INST. CORP.” “NEWARK, N.J., U.S.A.” A silver backing separates the patent information and has black writing that reads “MODEL 735” on the viewer left side; “No” is present in the middle; “8284703” is engraved on the viewer right side. In the middle there is a brass screw with the words “ZERO CORRECTOR” written in black around its circumference. On the viewer left side of the zero corrector is the patent information; “U.S. PATENTS” “1,779,574” “1,982,406” “2,073,790” and on the viewer right side continued patent information “U.S. PATENTS” “2,137,466” “2,274,441” “2,346,555”. Below these numbers are the “FOREIGN PATENTS” “FRENCH 862,770” “BRITISH 531,996” “CAN. 347,085” “CAN. 411,975” At the very bottom underneath there is the manufacturer’s location; “MADE IN U.S.A.” written in black on a silver background.There is also a blue case with white stripes and a red inner lining that would be used to protect the case. This would not have been originally sold with the exposure meter and was most likely hand made in an effort to protect the meter. Blue stitches hold the fabric together and are visible.

- Description
- (a)Gossen Lunasix exposure and colour meter in a pear shape with leather case. The light meter device measures the amount of light that is appropriate to achieve the proper exposure, indicating for the users which shutter speed and f-number should be selected. Along the top of the exposure meter in the viewer left corner is a white bulb-like part next to an open circular window that measures the amount of light present in the scene. When the converter slide, located along the viewer right side, is moved to the right and clicked into position the round window is open and ready to read the scene. At the top, on the face of the meter, the light measurement (scale) is present. This shows how much light is present in the scene and directly relates to the remaining scales on the meter. Below the light scale is a plexiglass film-speed setting disc with grooves that allow the operator to easily move the dial. In the middle of the dial there is the Lunasix manufacturer symbol. On viewer left side of this emblem is the DIN exposure index of the film in use; on the proper right side of this emblem is the ASA exposure index of the film in use. By moving the dial one adjusts the film-speed setting, which is indicated in the DIN and ASA boxes, whereby the index number is lined up against the triangular white marker in the respective window. A manual would have originally been sold with the object giving a more comprehensive overview of the film-speed table with a technical appendix. On the rear of the object in the viewer right corner one will see the correct position of the 2 batteries indicated through a tiny diagram. Below this is a metal battery chamber. Below this are the words “2 Batt. Mallory” “PX 625 o. PX 13”. To the viewer left of this writing is the ridged slide used for battery testing. Above the ridged slide are the words “Batt. Contr.” with a solid arrow below. Below the battery information is the table of footcandle (LUX) equivalents. In the middle of the table is the zero adjustable screw with an arrow pointing in both directions. AT the very bottom painted on the surface is the location of manufacturing; “GERMANY (WEST)” above a cutout window revealing the patent number; “4D01673”. (b) There is also a black leather case with the object. The inside of the case has gray suede lining, which would have helped avoid scratching and marking of the meter. The case has been carefully designed to retrofit the meter, which is apparent through the tiny leather strap present when the case is opened. These designs allow the object to be formly held into place further safeguarding it. At the bottom of the case there is a black button that allows the case to be opened and fastened shut. When the case is fastened shut, the name of the manufacturer “Gossen” appears imprinted and is upside down. Below this, also upside down, “LUNASIX 3” has been applied in silver ink. Along the viewer right side the case has a cutout that perfectly fit the converter slide. On the rear “MADE IN GERMANY” appears in a receded box with protruding lettering. The bottom of the case, where the button is located, contains an opening for the black string to be strung through. The string, which has been tied to the exposure meter, measures 49.0 cm and has a metal piece holding the ends of the string in place. This would have given the user greater security when working with the exposure meter.
