The Gossen Luna-Pro is a classic analog reflected and incident light meter. As a system meter, it will provide correct exposures in any situation. With its low end range value being -4EV, the meter has ample capacity for extreme low-light levels with very long exposures.
When a reading is taken and the meter's rocker switch is released, the indicator needle "freezes" making it easy to read off shutter/aperture combinations. More than just a superb handheld meter, the Luna-Pro S has a wide range of optional accessories to further increase versatility.
The Luna-Pro can be adapted to calculate the correct exposure for photomicrography with the Microscope accessory. It can be turned into a dual angle "spot meter" with the Variable Angle Attachment (7.5 or 15°). It can also be used to take through the lens readings from a large format camera's groundglass with the optional Flexible Fiber Optics Probe accessory.
This meter can also come in handy in the darkroom as well. The Enlarging accessory helps to find the right paper grade for black and white prints.
