Sekonic L-758DR DigitalMaster
The Sekonic L-758DR DigitalMaster is the world’s first multi-function light meter that can be programmed to match and be calibrated to the sensitivity of your digital camera sensor or type of film for perfect exposure control. It offers features such as Spot/Incident measurement modes, flash or ambient measurements, flash analyzing, PocketWizard wireless triggering built-in, PLUS Exposure Profiling, Pre-Exposure warning, 14 selectable custom settings and much more. The L-758DR measures light beyond the capabilities of your camera and ensure repeatable accurate and consistent measurements. In addition, the dynamic range of a particular digital camera or film can be stored, recalled and displayed. Using the USB transfer cable (included) and the Sekonic Data Transfer Software (included), a digital camera or film’s exposure profile can be uploaded from a computer (Macintosh® or Windows®) to the L-758DR. Up to three different digital camera or film exposure profiles can be saved and quickly retrieved with a touch of a button. With its Pre-Exposure warning indicators and adjustable mid-tone settings, the L-758DR puts the power of digital exposure control in the palm of your hands.
Exposure Profiling
Since no two digital cameras, camera and light meter’s or different types of film are likely to agree on the same exposure, they need to be calibrated to a standard. The L-758DR can be programmed to perfectly match the sensitivity of a digital camera senor or type of film for perfect exposure control. In addition, the dynamic range of the digital camera or film can also be stored. Up to three Exposure Profiles (digital cameras, types of film, file type or file type) can be stored and recalled quickly and easily. Exposure profiles can be created for the following measuring modes:
1. Reflected measurements (calculated from ISO 3 to 8000)
2. Ambient measurements (calculated from ISO 3 to 8000)
3. Incident measurements (calculated from ISO 3 to 8000)
4. Flash measurements (calculated from ISO 3 to 8000)
Pre-Exposure Warning
The dynamic range of a digital camera sensor or type of film can be stored, recalled and displayed on the meter’s LCD screen. This is a valuable feature that reveals the dynamic range limitation of a digital camera or type of film before capturing the image. Blinking pre-exposure warning indicators, displayed above the analog scale, alert the photographer when a measured highlight or shadow has met or exceeded the dynamic range. Clipping points (user defined dynamic range limits) add further control and customization for added exposure control.
Mid-Tone Adjustment
The Mid-Tone button acts as an exposure shift, moving the highlight or shadow within the dynamic range of the digital camera or type of film. Once the desired high light or shadow setting is selected, the pre-exposure blinking alert icon stops flash, indicating that the value is within the recordable range.
Data Transfer Software
Compatible with both Windows® and Macintosh® computers, the Sekonic Data Transfer Software automatically calculates the entered test data from a digital camera and creates an exposure profile. These profiles contain exposure characteristics for Flash, Ambient, Incident and Reflected exposure modes from ISO 3 to ISO 8000. In addition, the dynamic range at all ISOs are calculated and stored. Exposure profiles are transferred via a USB cable (included) from the Data Transfer Software (included) directly into the L-758DR. Once the data is completely transferred to the meter, it is automatically calibrated and programmed for the specific digital camera sensor or film loaded in its memory.
Four Meters In One
Independent programming of Flash, Ambient, Incident and Reflected measuring modes customized to your digital camera or type of film.
Working together (Incident and Reflected modes)
Measured values can be memorized and retained in both reflected and incident measuring modes. For example: A incident reading can be retained and displayed as a diffused mid-tone on the analogy scale (f-stop or EV scale), at the same time as reflected spot reading of a highlight or shadow can be measured and memorized. The result is a Highlight, Mid-Tone and Shadow measurement displayed on the meter’s analogy scale.
Analyzing Function
Simultaneous readings of flash and ambient light are automatically analyzed when the L-758DR measure flash and ambient light. The readings are displayed in three different ways on the LCD:
1. Combined readings of flash and ambient
2. Percentage of flash in the total exposure
3. Simultaneous display of flash, ambient and combined readings on the analog display
Retractable Lumisphere
A built-in adjustable incident dome (Lumisphere) provides full measuring in the standard position or when retracted, provides cosine-corrected light readings for individual light source measurements or flat artwork.
Illuminated Direct Display
Both shutter speeds and apertures can be displayed in full, 1/2 or 1/3 step increments plus 1/10 stop units to accommodate most camera manufacturer’s settings.
Exposure, Calibration and Filter Compensation
Exposure compensation of +/-9.9 EV Calibration compensation of +/-1.0 EV Filter compensation of +/-5.0 EV
Dual ISO Settings
The L-758DR offers the flexibility of taking a single measurement and displaying the f-stop and shutter speed for two different ISO film speeds, such as negative film and Polaroid proofing film. The second ISO setting is also ideal for calculating exposure compensation such as filter factors or bellows factors, without having to change the original film speed settings.
Cine Speeds
Complete range of full and half-frame speeds from 2 to 360 fps (frames per second) 28 cine speeds total.
Full-Featured Flash Measurements
1. Cord Flash Mode (Cumulative and Non Cumulative)
2. Cordless Flash Mode (Cumulative and Non Cumulative)
3. Radio Triggering Mode
All Weather Design
All buttons, switches and compartments are sealed and the meter housing has been constructed with durable, rugged conditions in mind. Ideal for shooting in sandy, rainy or humid conditions.
Spot with Digital Display
The L-758DR DigitalMaster features a rectangular 1° parallax-free spot viewfinder. In dim or bright light situations, the L-758DR DigitalMaster’s spot viewfinder displays f/stops, shutter speeds and more. The built-in spot meter measures both reflected ambient, flash or combined lighting. The optical finder also features an eyepiece with an adjustable diopter.
Built-in Radio Transmitter Module
Electronic flash units and/or cameras can be triggered wirelessly with the built-in digital radio Transmitter (compatible with all PocketWizard Digital Radios). Simultaneous triggering and measuring of flash units up to 100 feet away is possible. Its new easy-to-use Selective Quad-Triggering control (4 zone lighting), the L-758DR offers fast selection of which flash unit to trigger and measure independently with a touch of a key. Now you can individually measure several flash units wirelessly by the touch of the meter’s measuring button, without walking over to each light and turning it on or off. Wireless channel and Quad Triggering Zones are continuously displayed on the main menu.
Memory Mode
Up to nine readings can be memorized in incident or spot metering modes independently in both Aperture and Shutter Priority Modes. The memory function of the L-758DR DigitalMaster provides the photographer with an effective way of retaining and analyzing shadow, mid-tone and highlight exposure readings.
Full, 1/2 or 1/3-step Selectable Readings
Both shutter speeds and apertures can be displayed in either full, 1/2 or 1/3-step increments plus 1/10 stop units to match your film or digital camera; selecting these increments is quick and easy with custom software menu settings.
Exposure, Calibration and Filter Compensation
Independent incident and reflected exposure compensation of up to +/-9.9 EV can be easily set for custom film exposure corrections or for bellows extension factors. With the calibration, compensation setting of +/-1.0 EV, matching built-in camera meters or other handheld meters is a snap. There is even a filter compensation setting of +/-5.0 EV for filter factor compensation.
14 Custom Settings
The custom settings mode provides a quick and easy setup of individual meter preferences. The L-758DR’s features and modes can be turned on or off, as well as modified to fit the needs of the individual using the meter. Below is a brief list of some custom settings.
