and thanks you for the

confidence in our products!

With the D4 line of generators, Profoto offers a sophisticated tool of exceptional precision and versatility with a quantity of innovative, yet easy to use, functions that are the result of decades of collaboration with demanding photographers world-wide. The unique ergonomic design combines the positive feel of mechanical knobs and switches with the precision of digital technologies. Profoto’s special “Hybrid Flash Technology” uses advanced digital voltage stabilisation and individual capacitor banks to provide extremely stable flash power and colour temperature – from flash to flash and over the whole range, even when several flash heads are used. This makes the D4 generators the first choice for critical analogue and digital shoots, always guaranteeing exact and repeatable results.

Four asymmetric and individual adjustable lamp connections offer the same flexibility as several independent generators. In addition, our new “Profoto Studio” software makes remote adjustments via computer very simple, even when many generators are used in combination. We check that all Profoto equipment passes the quality and capability levels the most demanding photographers require. For this reason our flash equipment is the standard in leading rental studios in New York, Tokyo, Cape Town, Paris etc. and the most rented flash the world over.

Create your own light

The most important thing in photography is the light, and it is essential that the flash system offers complete freedom to create your own style. The Acute/D4 heads give you this possibil- ity: The light sources, the flash tube and the modelling light, are placed together inside the glass cover. What you see with the modelling light will be what you get when the flash fires. This makes it easier for you to adjust the light creatively. The reflectors are adjustable and lock easily into place.

Most reflectors can be moved forward or backward in relation to the optical center of the light source, effectively narrowing or widening the spread of light and changing the inten- sity and fall-off charakteristics as well. The Acute/D4 head and the Acute/D4 twin are sup- plied with a frosted and UV-coated glass cover, which together with the flash tube, produce a colour temperature perfectly suited to daylight film. In addition there are glass covers with adjusted filtration available, that anable the colour temperature to be changed.

The whole D4 system is modular. Every single reflector and accessory creates its special light and the unique Profoto focusing system offers you a possibility to create your own light with only a few different light shaping tools.
