Colour Touch Screen Interface and Design

• The touchscreen 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 touchscreen. 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

Wireless Flash Power Control

• Wirelessly control and modify the power output of PocketWizard-mounted/enabled strobes or flashes directly from your meter
• Three sliders allow you to dial up or dial down flash power from full to 1/64th power directly from the meter
• Up to three zones can be managed; when working with more than one zone, determine each zone's values individually in order to establish desired lighting ratios, then an overall exposure sum will be determined

Versatility Between Metering Methods

• Ability to measure incident or flashlight 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

ColorChecker Passport

The X-Rite ColorChecker Passport provides three photographic targets in a compact, durable case which minimizes colour patch fading. Utilizing the included camera calibration Software, the ColorChecker allows you to quickly and easily capture accurate colour, enhance portraits and landscapes, and maintain colour control and consistency from capture to edit. The Creative Enhancement Target provides enhancement patches and allows you to check shadow details and highlights and check and control colour shifting. The Classic Color Target lets you evaluate specific colours and create a DNG profile and the White Balance Target will allow you to have consistent, customized, in-camera white balance. Also included is a built-in stand to provide you with optimal shooting angles.

Sekonic Gray Balance Card

Also housed in the ColorChecker Passport and only available bundled with the LiteMaster L-478-Series meters is the specially produced Sekonic Gray Balance Card. The purpose of the Sekonic Gray Balance Card is to enable reflected-light calibration when using the separately purchased Viewfinder 5º attachment. There is an "Incident Only" calibration method available with Sekonic's Data Transfer System that needs no additional accessories.

Data Transfer System

Sekonic's Data Transfer System (DTS) simplifies exposure and meter calibration using the X-Rite ColorChecker Passport with Sekonic Gray Balance Card. With Sekonic's DTS Version 3, you can create an exposure profile and map out the dynamic range of your DSLR or digital video camera. Transferring this data to the Sekonic L-478DR meter enables it to recognize which details of a scene or subject will be properly imaged and which will be over or under the range of the camera. There are two ways to calibrate the L-478DR meters using Sekonic's DTS Version 3 software: incident-only calibration using Sekonic's DTS enables creating exposure profiles for precise metering without need for additional accessories, and reflected-light calibration requires the L-478-series Viewfinder 5° attachment, available separately, to read the Sekonic Gray Balance Card for calibrated reflected-light readings.
