Tutorial: Using the Gossen Luna-Pro Analog Light Meter

Note: If you don’t know why you need a light meter check out Light meters are dead, long live the light meter!

The Gossen Luna-Pro is the best light meter I’ve found used for less than $100. Is is an older model analog light meter and as a result takes a little more effort however as you will see it is still quick and easy to take a reading and you can take the money you saved and put it towards some new glass.

Side note: The Gossen Luna-Pro also works with flash which is a nice perk.

Here is a quick tutorial for taking a meter reading with the Gossen Luna-Pro (Other analog meters should be similar).

Step 1: Set the ISO (ASA).

  1. Turn the inner wheel until the ASA arrow points to the desired ISO.

Step 2: Taking a meter reading:

  1. Hold the meter near the subject and point the white bulb towards where the camera will be.
  2. Press the red button on the side to activate the meter
  3. Turn the outside wheel right/left until the needle lines up with “0”

Step 3: Reading the exposure values:

  1. Now that the reading is captured. The proper shutter speed and aperture values will line up as illustrated below.In this example a shutter speed of 1/125th @ aperture ƒ2.8 will provide proper exposure.

    Note: Any  other shutter speed + aperture combinations that line up on the meter will produce the same exposure.

  1. Thanks for the tips and for the link to the Gossen Luna Pro F instruction manual. I just started getting back into film photography and bought several old cameras, two of which do not have a working meter. The Luna Pro F was my next purchase, and I’m already finding that it’s worth way more than what I payed for it, inasmuch as it’s a very good quality meter that gives good, consistent readings. Also, the 9v battery is very easy to find.
