Imaging today requires consistency in output and colour whether shooting ﬁlm or digital. Profoto’s unique “Hybrid Flash

Technology” ensures repeatable performance from exposure to exposure over the life of the generator.

This is made possible through the use of advanced electronics and microprocessors, combined with the time-proven

approach that has made Profoto the industry leader in electronic ﬂash systems.
