Shooting off-camera flash photography is challenging. Optimal exposure settings requires a knowledge of how to balance ISO sensitivity, aperture level, strobe power and strobe proximity to the subject. Because strobe power varies dramatically not only between manufacturers and models but also when external elements such as umbrellas, soft-boxes and lighting gels are used, quickly determining correct exposure settings can be challenging at best, and frustrating at the worst. KeyLight PRO removes all of this guesswork. Easy-to-use calculators quickly and clearly display optimal ISO levels, aperture settings, strobe power levels and strobe-to-subject distances in an intuitive, familiar interface. For the more advanced photographer, the Key Falloff calculator will calculate the proximity of the strobe from the subject in order to meet a desired exposure value falloff over a specific distance. For example, the area behind a subject is 10 feet away, should be 3 stops underexposed relative to the subject, and the strobe is firing at 1/4 power and the camera is at ISO 400. What should the aperture setting be on the camera? With KeyLight PRO, the answer is a tap away. How many strobes does KeyLight PRO support? The Virtual Gear Bag provides an unlimited number of strobe makes, models and settings, and the Strobe Library provides over 100 pre-loaded strobe model configurations. The Gear Bag is readily accessible on all of the calculators, providing quick, easy and accurate exposure settings when swapping between your strobes. Only using one strobe? Keep multiple "set ups" in your Gear Bag under a variety of configurations: bare bulbed, gelled, soft-boxed, umbrellaed, neutral-density filtered, wall-bounced, go-bo'd. There is no limit to the number of ways the light from a single strobe can be modified. Create as many configurations for these light modifiers as you need, and know in an instant how to most effectively utilize them. KeyLight PRO. Control the light.
