Gossen products can determine the best exposure setting for any given picture
Gossen is a German company that specializes in the measurement of light. This has a lot of applications, including in the industrial and medical fields, but is often used by photographers to measure exposure before taking a picture. Gossen have released many different exposure meters, including the Digiflash and the Digipro. Both of these units measure in either reflected or incident light mode, and are similar in their general operation. Understanding the basics of the Digiflash and Digipro will give you a good understanding of operate Gossen products.
Instructions
1. Put the unit in "Incident Light Mode." This is done by turning the sensor to the left, so that it is pointing from the subject's direction to the camera's direction. On both units, this sensor is located on the top of the unit's back side. The white orb needs to be pointing back at you (in "Incident Light Mode") for most images to ensure that you can determine the correct exposure setting. If it is pointed at the subject (known as "Reflected Light Mode"), then the reading will be tainted by the reflective qualities of your subject. This can be advantageous in some situations, but that will come when you're familiar with the device.
2. Press the "Function" buttons to select the desired function. On the Digiflash, pressing the "Function" button will cycle through the functions available, displaying the next one with each button press. This can be used to select "Ambient" or "Flash Light" modes, "Timer," "Watch," "Alarm Clock" and "Temperature" modes. The button is located toward the bottom of the unit, directly above the word "Gossen. On the Digipro, the "Function" buttons are located on the right-hand side and are used the access the options displayed on the top of the display screen. You can select "Shutter Priority," "Contrast Measurement," "Aperture Priority," "CINE" and "Exposure Value Measurement" modes.
3. Select the "ISO" option to select your desired film speed. On the Digiflash, this is done by pressing the "Function" button until "Ambient Light" is displayed, and then holding the button for more than two seconds. There will be a confirmation noise, and the "ISO" value at the top of the display will begin to flash. Use the "Measuring" key to select the desired speed. This is located directly underneath the display screen. The button can be held to advance the number more rapidly. On the Digipro, use the "Function" buttons to highlight "ISO" at the top of the screen, and then use the "Value" buttons to select the desired film speed. The "Value" buttons are on the left-hand side of the unit and are used to change the values of all options. Press "Function" to save your settings.
4. Press the "Measure" button to take your measurement. This will be displayed on the display screen as an "EV" number. The "Measure" button on the Digipro is located between the "Function" and "Value" buttons.
