The LiteMaster Pro L-478D-U Light Meter from Sekonic is equipped with a large and user-friendly 2.7" color touchscreen LCD, simplifying the process of incident metering for both ambient and flash light. A key feature of this device is its ability to provide precise control over the flash's power in increments of 0.1.
A distinguishing characteristic of the L-478 light meter series is its expansive color touchscreen, which facilitates quick adjustments for settings related to both ambient and flash metering. This meter is highly versatile, operating within a range of -2 to 22.9 EV at ISO 100. Furthermore, for contemporary hybrid shooters, this model enhances its traditional stills capabilities by offering two dedicated video modes: Cine and HD Cine. These modes allow users to select frame rates from 1 to 1,000 fps and adjust shutter angles from 1 to 358°, with an ISO setting of 850 specifically for Canon cinema cameras.
To ensure optimal performance, the device is equipped with a comprehensive array of functions and features designed to provide users with the best tools at their disposal. Among these is a flash analyzing function that enables simultaneous use of ambient and flash light, allowing photographers to fine-tune their preferred light mix. Additionally, with the included Data Transfer Software, users can perform Exposure Profiling for their cameras using the optional 5° viewfinder, which displays dynamic range limits and ensures accurate exposure. Complementing this is a Filtration Compensation Mode that accounts for filter factors, accommodating adjustments of up to 12 EV for landscape photographers utilizing high-density ND filters. Other notable features include a contrast function for brightness comparison, a memory mode for storing up to 8 readings, and the capability to measure illuminance or luminance.
