The Sekonic Litemaster Pro L-478D Light Meter is an incident and flash meter featuring a color touch screen interface. The touch screen-based navigation lends itself to a highly intuitive and efficient workflow, allowing you to quickly modify exposure settings and navigate menus. This meter is also highly versatile and capable of measuring flash, incident and reflected light for still, HD video, or cine applications.

The L-478D can be customized or adapted to your own specifications; depending on the metering modes you use most often, you can hide certain modes to create a more streamlined menu system. 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 more 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.

Color Touch Screen Interface and Design

  • The touch screen provides a more intuitive style of navigation and allows you to simply touch the settings you wish to adjust. Menu navigation is intuitive and the handling of various configurations becomes an expedited process.
  • Simple visual layout provides a clear view of your exposure setting and permits customization in regard to the information you wish to be displayed (including a choice of analog exposure scales (EV or f/-stops); 1, 1/2, or 1/3 step increments; the inclusion of 1/10 stops; and the option to hide metering modes you do not use frequently).
  • One physical menu button provides access to a more in-depth menu system that is then navigated through the touch screen. This menu allows for you to program exposure profiles and modify custom settings for your meter.
  • Measure and memory buttons are located on the side of the device for recording and initiating exposure readings. A PC sync terminal is located on the bottom of the device for direct, corded flash metering. A USB terminal is located on the side and provides a connection point to your computer for firmware updates and for loading exposure profiles to your meter. The attached light receptor features a retractable Lumisphere that can be rotated 90° clockwise or 180° counter-clockwise. It is also removable in order to facilitate the use of optional attachments.
  • Versatility Between Metering Methods

  • Ability to measure incident or flash light and display exposure readings as f/-numbers, shutter speeds, or ISO settings for use with still imaging, HD video, and cine uses. Exposure constants also include frame rate and shutter angle for a variety of motion uses.
  • Also capable of measuring illuminance as footcandles/lux or luminance as candela per square meter/foot-lamberts.
  • Flash metering can display the percentage of flash-to-ambient light within the scene for precise lighting ratios.
  • Comparative metering can be accomplished by using the AVE/EV function; allowing you to set a standard reading and have subsequent readings shown as the difference in exposure value.
  • Cinematic modes offer creative options for setting frame rates between 1 to 1000fps or shutter angles from 1° to 358°.
  • Filter compensation mode enables you to directly apply the effects of filters to your exposure reading. Up to four different filter factors can be applied at once, and up to 30 different filter factors can be stored for use (24 common filters are pre-programmed, including CTB, CTO, ND, +/- green, and 85 amber filters).
  • Custom Profiling

  • You can enable and disable different metering modes from showing up in menus, allowing you to configure the meter to your own personal workflow.
  • Calibration and custom profiling can be accomplished in accordance to your own personal camera by executing a series of exposure tests, processing the tests through Sekonic's Data Transfer Software (included), and outputting the results as a personal profile for use with your meter. These personal profiles confine your meter to work within your specific camera's dynamic range (up to 10 distinct profiles can be saved). Profiles can also be modified or created directly through the meter.

    question

    Will this meter measure the temp. of the light in degrees Kelvin?
    Asked by: Michael
    Sorry. No. No photo meter is designed or capable of reading light color temperature. Color temperature requires at least 2 photocells to locate the Red-Blue point of the light. Photometers are filtered to not read higher or lower than visual color.The Sekonic C-500 can read color temperature. If you plan to use LED lights, I recommend the C-700 as it reads the full slight spectrum and can detect spikes in the light source.

    question

    Can this meter trigger Radio popper Jr II & pocket Wizard plus 3from the meter?
    Asked by: Anonymous
    Unfortunately, this meter cannot trigger a Radio Popper JR II or a Pocket Wizard Plus III. The L-478DR on the other hand can trigger the Pocket Wizard receivers only. Please see the link for reference: http://bhpho.to/1i0snFH

    question

    ON the Sekonic web site It states you must pick the frequency and language when ordering. I did not see where to do this on your page. Is the L478d that you sell set for English and USA frequency?
    Asked by: Anonymous
    Being that we are a USA dealer, we are only permitted by USA Federal Law to sell versions designed with frequencies used in the USA (aka FCC version). All of the PocketWizard compatible devices we sell are compliant with this. If you have purchased other PocketWizard transmitter/receiver devices in another region, you would need to purchase all of your devices in that same region so they would all be on the same frequency.
