CL-200X Understanding High Speed Sync

The purpose of this article is to acquaint you, the photographer using electronic flash, with the working mechanics of high speed sync; what it is, what it isn't, and how it can be confidently incorporated into a functional outdoor portrait lighting workflow.

What will be presented is a practical way to determine the exposure contribution of a specific flash/modifier combination, once the X-Sync guide number is defined by measurement, and the resulting shift in light value output, when incorporating high speed sync, at various shutter speeds.

Recreating Hollywood Glamour

Recreating Hollywood Glamour

From a long time and perhaps obvious fascination with the glamour portraits of Hollywood Stars from the 1940's - 1950's, I wanted to recreate that look with my own photography. My Uncle Julian was stationed in Japan during the close of WWII and was the editor and chief of Stars and Stripes magazine. His camera of choice was a 4x5 Speed Graphic. Looking at some of the famous glamour portraits of that time, I became fascinated with the lighting style and an avid fan of Film Noir. The lighting techniques achieved with Fresnel lens based spotlights, was nothing less than remarkable in my mind

Creating dramatic images draws on the imagination of the photographer. Past experiences, previous and self assignments as well as trying new approaches, provides a level of confidence from which the creative photographer will go the extra mile to bring the components together that will define a work of art and a salable image.

What I Learned from '50s Classical Portraiture

What I Learned from '50s Classical Portraiture

In the Hollywood Golden Age of Film Noir, there existed an expertise of crafting light and shadow, building suspense, drama and exquisite beauty. 

This adventure, depicted in my new book, "Creative OCF Lighting Techniques for Photographers", would ultimately fast forward to the writing of this book. That is, define a course for my education and professional vocation and ultimately resulting in the sharing of what I had learned; through workshops, my OCF Lighting book and one on one tutoring.

In 1956, the school I was attending in Ojai, California, built a black and white darkroom. We spooled 35mm Tri-X movie film ends from the Air Force photo lab into 35mm film cartridges and loaded vintage 35mm cameras. In the spirit of a movie director, I searched for interesting and story telling ideas to photograph. I then processed my film and printed a contact sheet of the 30 plus images I had captured.

As a Digital Artist, we are ultimately in the industry of selling a fantasy, as the best portrayal of our photographic subject, essentially, our take or our rendition of photographic story telling.

In the days of film, optical compositing required an elaborate process of masking and post production art work, often requiring the services of seasoned professional painter or illustrator to create the final artwork or ad campaign.

Anatomy for a Vintage Styled Photo Shoot

In 1953, Marlin Brando stared in a film, "Wild One," about a motorcycle gang. The motorcycle Mr Brando rode in the film was a British made Triumph. Later in 1959, the famous Triumph Bonneville was born, named after the famous Bonneville Salt Flats in Utah. Today, the Triumph Bonneville has been resurrected as a modern motorcycle. The '50s era Bonneville was the theme for this vintage styled photo shoot. Our models, Madyson Wilmot and Bradley Perkins.

A New Light Shaping Toolkit for Speed Lights

A New Light Shaping Tool

Since my days at Vivitar in the mid-70's, as a New Product design engineer, involved with the design and development of electronic flash systems, the shoe mount flash, applicable light modifiers and accessories, have remained a prominent footnote in my mind’s eye for consideration in the design of new portable flash ideas.

Now over 40 years later, with the advent of new digital technologies, I have been busily at work and in the process of designing, what I would consider to be the perfect light shaping toolkit for speed lights. Not just another gadget, but a complete and straightforward approach for the design of quality light shaping tools.

In the meantime, a short while after my successful publishing and launching of my new coffee table book, "Creative OCF Lighting Techniques for Photographers" and subsequent listing on Amazon, I decided it was now time to revisit the perfection of a portable light modifing toolset for speed lights. 

 Understanding the Nature of Portable Strobes

It may be well at this time to review the basic premise of speed lights. Prior to the advent of portable battery powered flash units, magnesium wire filled flash bulbs were used to provide portable on or off-camera flash. They were fitted with circular reflectors and a simple flashlight battery ignition circuit to ignite the bulbs, timed with the camera shutter.

When portable electronic flash units were first introduced, such as the Heiland Strobonar in the early 50’s, an oval shaped reflector was used to widen the projected beam to cover the wider 2:3 aspect ratio of 35mm film. By adding a fresnel lens in front of the flash tube reflector, the projected beam width of the flash was optimized to cover a similar angle of view as a 35mm lens. This concept lead the direction of portable flash units towards light output efficiency to save on battery life and number of flashes per set of batteries. The initial design required a selerate battery pack. However, in 1958, with the acquisition by Honeywell of the Heiland design, they introduced a self contained unit, the Futuramic Strobonar, with oval flashhead and integrated handle. 

As the photo below illustrates, my approach is to modify the shape of the light projecting from a speed light from rectangular to circular, presently in the form of an adapter. The intention for this is twofold:

  1. Breaking up the harsh pattern of light associated with speed lights, by use of a Fresnel lens, potentially focusable, to condition the light into a smooth circular pattern with minimum light loss.
  2. Provide a 100mm circular interface to easily adapt to the Profoto OCF Light Modifiers.

A Modular System of Light Modifiers

Captivated by the lighting styles of Hollywood in the 40's and early 50's, a beautiful film noir portrait is easily attainable with the Fresnel lens and the Profoto barn doors. Add to this, snoots, grids, gels, umbrellas, and the OCF integrated softboxes, Octa, Strip and Rectangular.

To provide accurate light positioning for film noir portraits, my initial prototypes also incorporated an LED modeling light.

DLP Profoto OCF Speed-Light Adapter

A couple of years ago, mid 2015, Profoto introduced their OCF line of light modifiers, specifically designed to be used with the B1 and B2 Li-Ion portable strobes. These OCF  branded light modifiers are lightweight and elegant and surprisingly well priced. My immediate thought upon seeing them was to configure a means of interfacing them with speed lights. In my mind, a kind of perfect marriage.

Here are a few photos which describe some detail about my OCF Lighting Adapter. As some may know, there are a variety of products on the market which make the effort to usefully modify the light quality of a speed-light. Many are inexpensively made and have questionable effectiveness when it comes to producing quality light, that is light which renders beauty in a portrait. In my new book, "Creative OCF Lighting Techniques for Photographers", I spend some time describing light quality. As a former design engineer for the Vivitar Corp., I was concerned with designing quality products. Most specifically, to this article, products pertaining to photographic lighting with small and compact light sources. Essentially, the speed-light.

A few companies over the years, introduced some innovative designs relating to portable lighting. Companies such as Ascor and Quantum. They endeavored to realize their designs as a flash system. Fairly recently, Profoto introduced their portable flash units, B1 and B2. Shortly thereafter, they introduced their OCF line of light modifiers, specifically designed for the B1 and B2 portable flash units.

Upon seeing this system, my engineering mind went to work to explore the possibility of adapting these lightweight and cost effective OCF modifiers to speed-lights. It turned out to be straightforward and I was able to build some prototype adapters from components I found at Lowe's.

Perfecting the Design

I noticed that the relative diameter of the Bowens mount and the Profoto flash units were very similar in diameter. With ABS 3" piping from Lowe's and a shower light lens, I was able to fashion an adapter from the popular Bowens speed-ring mount to the Profoto dimensions, as needed to accept the line of Profoto OCF light modifiers. This was a revelation, as I could now design a complete lighting system, suitable for studio and outdoor use.

As seen in this photo, my adapter provide the interface for Speed-Lights to Profoto OCF

Once I had sufficient quantity of prototype adapters, I fashioned a lighting system for four speed-lights and began testing its effectiveness. The results were exceptional and I began introducing the idea in my Lighting Workshops.
