Pro-D3 750 Duo kit includes two flashes -- With a flash power of 750 or 1250 Ws and a recharge time of just 0.5-0.8 seconds at full power, the Pro-D3 is the ideal solution for high-volume production because it offers a high firing rate that can be sustained for hours on end. There are three shooting modes: ECO to increase equipment autonomy and colour consistency, BOOST for more power and speed, and FREEZE to eliminate motion blur by exploiting the shorter flash duration of up to 1 /75000th of a second. Pro-D3 also features an energy-efficient LED modeling light. It offers more light intensity than a 400 watt halogen lamp with only 15% power consumption. In addition to saving on energy costs, this keeps the temperature of the light modelling accessories low, thus extending the life of the light. In addition, the modeling light has a fixed colour temperature balanced with daylight and diffuses light like a flash. The power of the Pro-D3 is adjustable over a range of 11 f-stops, with an accuracy of 0.1 f-stop. For perfect synchronisation between devices, the Pro-D3 is equipped with Profoto's latest user interface and AirX technology. The result is a perfectly smooth workflow.
