We are pleased to bring the most advanced integrated studio flash system ever invented by Paul C. Buff
Our new building will be opened in mid-February 2018. At this location you can see the articles of Paul C. Buff and try them in our demo studio.
IN THE BOX
IGBTEven the most expensive professional monolight flash units usually control flashpower by varying the voltage applied to the flash capacitors. This simple and inexpensive method has three distinct limitations to the achievement of truly professional performance: 1. The range of power reduction is typically limited to 1/8 to 1/32 power, often resulting in an inability to achieve low aperture settings with close lighting techniques. 2. As power is reduced, the flash duration becomes longer - typically twice as long at minimum power relative to maximum power. The median t.1 flash duration of the ten most popular pro monolights ranges from 1/200 second to 1/400 second â€“ too slow for sharp freezing of action in sports, dance and other rapid movement shots (see graphs on page 15). 3. Color temperature typically varies by 75ÂºK to 80ÂºK per f-stop of power reduction, resulting in about 400ÂºK color difference between minimum and maximum power. The Einstein unit employs proprietary advanced digitally controlled IGBT technology to control flashpower. This results in an extreme range of power reduction (1/256 power) in precise 1/10f stops. As power is reduced, the t.1 flash duration also decreases dramatically instead of increasing. This technology allows the Einstein unit to maintain a constant color temperature throughout the entire 256:1 power range.
ACTION Mode and CONSTANT COLOR ModeIn Action Mode, the t.1 flash duration shortens rapidly from 1/588 seconds at full power to 1/13,500 seconds at minimum power for incredible action freezing capability, but the color temperature increases as power is reduced. In Constant Color Mode, the t.1 flash duration drops less rapidly, to a minimum of 1/8000 second, while maintaining a constant color temperature of 5600ÂºK (+/- 50ÂºK) throughout the entire power range. The internal processor controls the accuracy and repeatability with very high precision.
ACTION ModeIn Action Mode, the color temperature rises as power is reduced, but the t.1 flash duration is minimized even further for maximum action stopping capability where absolute color consistency is secondary to motion freezing. At 1/2 power in Action Mode, the t.1 flash duration is approximately 1/2000 second and the color temperature is approximately 5750ÂºK (absolute values of flash duration and color temperature are indicated on the rear LCD display).
CONSTANT COLOR ModeIn this mode, the emitted color temperature is held constant at 5600ÂºK, plus or minus 50ÂºK at any power setting or input voltage. At full power, the t.5 flash duration is 1/1600 second and the t.1 time is 1/568 second. As power is reduced to 1/2 power the color remains constant, while the flash duration decreases to 1/1351 second t.1 (note that with IGBT control, the t.5 spec is no longer meaningful, so only the t.1 flash duration appears on the rear LCD display). As power is further decreased, the color temperature remains constant and the t.1 flash duration falls ultimately to 1/8000 second at the lowest power settings.
