The Sekonic L-478D Litemaster Pro Light Meter will make a feature rich addition to your photography kit. Featuring an innovative 2.7 inch colour LCD touchscreen, the L-478D light meter combines a bright, easy to read display with a clear intuitive interface. The meter also supports exposure profiling, which allows you to customise the light meter to your camera’s specific dynamic range. This function helps you determine if there is information loss in the shadows or highlights of your photos. For anyone who needs to calculate accurate exposures quickly and easily, the Sekonic L-478D Litemaster Pro Exposure Meter is the perfect tool for the job.
Adjustable Lumisphere - Swivel measuring head with retractable Lumisphere.
Simple Operation – Features an intuitive interface with an easy to read and understand graphical design. Effortlessly adjust settings by tapping or sliding icons on the screen.
Flash Analysing Function – The L-478D can measure ambient light and flash simultaneously then display the percentage of flash in the total exposure. The meter’s LCD display uses colour coded lines to graphically represent the flash to ambient light ratio in your photo.
Exposure Profiling - Every camera and lens combination has a unique dynamic range. Sekonic’s included Data Transfer Software enables quick dynamic range mapping and meter calibration for the most precise control of light. The software will also allow you to create custom meter functions to help simplify your workflow.
Contrast Function - The L-478 contrast function simplifies setting up lighting ratios and can help with checking the evenness of a background or scene.
