Thank you for choosing Profoto.
Follow the instructions in this booklet to use your new product.
Thanks for showing us your confidence by investing in an AcuteB Head. For more than three
decades we have sought the perfect light.What pushes us is the conviction that we can offer even
the most demanding photographer yet better tools.
Before our products are shipped we have them pass an extensive and strict testing program.
We check that they pass the quality and capacity levels the most demanding photographers
require. For this reason our flash equipment is the standard in most rental studios in New York
andTokyo and the most rented flash all over the world.
Quality of Light
The Profoto system consists of different generators built and designed to meet the needs of
the most demanding photographers. Yet the most important thing is the light you create, and
it is essential that the system you use offers the freedom to do that. The light source, both the
flash tube and the modeling light, is placed high and free in the flash head.This makes it easier
for you to adjust the light and use your creativity. Most reflectors can be moved forward or
backward in relation to the optical centre of the light source, effectively narrowing or widening
the spread of the light and changing the intensity and fall-off characteristics as well. Every
single reflector and accessory creates its special light and the unique Profoto focusing
system offers you the possibility to create your own light with only a few different reflectors.
Enjoy your Profoto product!
