Litemaster Pro L-478D Light Meter
Digital Light Meter
The Sekonic Litemaster Pro L-478D Light Meter is an incident and flash meter featuring a colour touch screen. It is capable of measuring flash, incident and reflected light for still, HD video, or cine applications.
The L-478D features customizable menus, with the ability to hide certain modes that are used less often. Exposure constants include shutter speed, f/-number, ISO, shutter angle, and frame rate; and the exposure variable can be decided upon depending on the situation you are working in. Illuminance and luminance values can also be taken, which are measured in footcandles/lux or candela per square meter/foot-lamberts, respectively. For more fine-tuned results, you can create and input personal profiles, allowing the meter to display exposure settings in accordance with your specific camera's dynamic range and clipping points.
Other settings available include the ability to memorize up to 10 different exposure readings in order to refer back for comparative overall measurements. The AVE/EV setting allows you to make one master exposure reading and have subsequent readings displayed as differential values based on the master exposure value. When working with flash metering, the flash exposure values can be expressed as a percentage of the flash-to-ambient light, giving you the ability to easily alter and previsualize lighting ratios. Filter compensation and exposure compensation settings can also be applied in order to remove the necessity to apply different filter factors after a meter reading has been taken.
