Flash Duration Measurements
Understanding flash duration is the first step in freezing fast-moving subjects. Since all cameras are limited to relatively low sync speeds, stopping motion in a single image is often achieved by leveraging short flash durations with the camera’s max sync speed. A long-held secret of some of the world’s most talented photographers, the key to freezing action consistently is found in being able to measure flash duration. Photographers are now able to do this easily for the first time, demystifying one of photography’s most challenging techniques.
Radio Control Modules for Wireless Triggering
Having pioneered wireless exposure measurement, the L-858 Speedmaster Pro expands upon this ground-breaking innovation by adding functionality for Elinchrom Skyport and Phottix Strato II/ Ares II users allowing more photographers to experience the benefits of wireless freedom.The PocketWizard module photographers can easily trigger any PocketWizard wirelessly and control the power of their lights with any Control TL Compatible Unit.The Combined Elinchrom & Phottix Module, photographers have full Skyport triggering and power-control capabilities, while Phottix users have Strato II and Ares II triggering capabilities.
Increased Light Sensitivity
Increased ISO capabilities in today’s cameras have created a need for light meters to increase their ability to measure light in the dimmest of settings. With an additional 3-stops of light sensitivity for incident light, 2-stops of light sensitivity for reflected light (spot), and an ability to capture a reading down to 0.1 lx of Illuminance, accurately metering scenes lit by candlelight or getting the right measurement for long-exposure night photography is now a possibility.
HSS Flash Measurements
The L-858D is the first meter of its kind that can measure the stroboscopic pulses fired from strobes when they are used for Hi-Speed Sync. Finally, photographers now have an accurate way of measuring their lights when they want to overpower the sun or achieve a very shallow depth of field through using HSS.
Flash Analyzing Function
The L-858D is especially useful for on-location shooting to lighten shadows or reduce background detail. That’s because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.
Determining the Dynamic Range of your camera.
Shoot with the equipment you use most. Make tests under daylight and studio lighting. Exposure Profile Target requires an 11-shot bracket (0, +/- 5EV). Exposure Profile Target II shown at the right requires a 3-shot bracket (-3EV, 0,+3EV). Make a spot reading of 18% reflectance tone and incident reading in front of target and record data. Shoot the bracketed shots based on incident light measurement.
Download test images into computer. If shot in RAW, convert to TIFF for computation. Enter ISO, incident, and reflected light shooting data. Then select images and press OK to watch the Sekonic Data Transfer Software program graph the dynamic range of your DSLR camera. Save the data for transfer to the L-858D.
Full information Spot Viewfinder
The 1-degree spot meter has a broad reading range from EV 1 to EV 24.4 for ambient light and measures flash down to an amazing f/2.0. Its large, bright viewfinder with diopter correction and full-information data display give you everything you need to make the right exposure decisions without having to take your eye from the eyepiece.
