Intoduction: The Profoto D4 Air

Introduction Profoto’s D-line of packs and mono heads sits in the middle of the company’s line up of studio strobe lighting, a bit less lofty than the company’s Pro line and more expensive and far more sophisticated than Profoto’s entry-level set of Acute packs.  “D” might well stand for “Digital” with D1 monoheads and D4 packs.  All use tenth-stop digital fine tuning and wide-ranging power.  “Air” equipped heads... Read More

Introduction: The Profoto Air Remote

  Introduction The Profoto Air Remote transceiver can be purchased from Samy’s Camera here. In recent years, the single aspect of strobe lighting to advance most noticeably has been control.  Strobe packs like the Broncolor Senso (reviewed here) and the Profoto D4 now offer precise digital control of flash power in compact, go-anywhere boxes.  With wide-ranging power and asymmetry, advanced packs like theses have practically done away with ND filtering and separate... Read More

What’s Up With “Flash Duration”?

Flash Duration? A topic of great discussion around the studio lately has been flash duration.  What is it exactly and what’s all the hype?  Two things have become clear – it can’t be had without compromise, and there are a lot of terms on the chalk board. In simple terms, studio strobes function by filling slowly with a bucket of electricity and pouring it quickly out through flash tubes.  The blink we see is one quick splash of light, but the reality is... Read More

Field Test: The Profoto Acute2 Ring Flash

Introduction: Ring flashes, in their various forms, are a unique way to illuminate a subject and perhaps none more frequently represents the strange breed than the Profoto Acute 2 Ring Flash.  It’s a big, sturdy donut of a light, designed to surround a camera lens, throwing intense and even light on a subject, seemingly from the lens itself.  Ring lighting creates unique effects with shadows and highlights and has been used to great effect by a range of photographers. ... Read More

High Speed Strobe Test: The Profoto Acute 2R 1200

Introduction While perusing the stats, photos from a number of my test shoots, and thinking through my review of the little Profoto pack sitting on my desk, I kept coming back to one number, “.09”.  It’s the number of seconds Profoto claims it takes the Acute 2R 1200 to recycle at minimum power.  That’s better than ten frames per second, better than 10 Hz from a strobe pack under $2,000 and smaller than a Mamiya RZ. I wanted to set up an informal studio... Read More

Introduction: The Profoto Acute 2R 1200

Introduction The first thing a photographer is likely to notice about the Profoto Acute 2R 1200 pack is its tiny size.  This is a little pack, especially for one with 1200 W/s, 6 stops of adjustment range, and the ability — according to my informal tests — to fire consistently at up to 11 frames per second (at its lowest power setting).  It feels beefy, very well constructed, nicely labeled, and has a cute rubber antenna for its built-in Pocket Wizard radio remote receiver.
