Save £60 on usual price A professional photographic light meter with 1° spot metering facility, the L-758D DigitalMaster can be precisely profiled to match the camera being used. Every digital camera has its own limited tonal range (the dynamic range) which it's capable of capturing. With digital cameras, this varies depending on the sensor type, processor and type of file compression used. Using the Sekonic Exposure Profile Target II (not supplied) a camera's exposure profile can be evaluated via a computer, and then transferred to the meter. Data can also be directly entered into the meter. In use, if highlights or shadows fall outside the camera's dynamic range, warning indicators blink on the LCD panel. Supplied with 1 x CR123A battery, case and strap.
