Of course, choice of actual ISO has a direct bearing on a proper exposure. So, for a given B&W film, what ISO should be used on the light meter? The answer can’t be generalized because of variations of film, developer, even local water. Personal testing should be done. Actual ISO values can be as low as half of the nominal ISO. I.e., reduction of exposure by one stop is needed.įilm manufacturers often assign nominal ISO ratings higher than those that are warranted. So, if a scene has a dark area where detail is desired, the exposure for that area should be adjusted to move that dark area to Zone 4. Consequently, a photographer must apply judgment as to which zone should be selected. When using a spot meter, please realize that a light meter will always return a Zone 5 result. Tonal differences cannot be adequately achieved when Zone III is the choice. Often, these areas get placed in Zone III which puts the development too low on the development curve, the so-called toe of the curve. In a nutshell, the Barnbaum recommendation for B&W film is to place the darkest area of the image where you want to see detail in Zone IV (or even higher). Bundesautobahn 7, Bavaria, Germany, photo made in November 1971, one of my first photos. ILFORD Delta 100 developed in Pyrocat HD, developed semi-stand. Hasselblad 503CX, Zeiss Planar 3.5 100mm. We’ll examine methods to make use of those higher stops. But film itself can record well beyond ten, even up to 16 stops. Many would say that a B&W image can absorb ten stops of light since photo paper spans ten stops. Photographers are familiar with stops of light. Study of the Zone System is best achieved by a detailed write-up which can be found in Chapters 8 and 9 the Barnbaum book. The System is well documented in various sources - one of the best is The Art of Photography by Bruce Barnbaum) It provides a way to use a light meter to drive a desirable exposure to gain sufficient details in the darker areas of the scene where details are wanted. Kodak T-MAX 100 developed in HC-110.Ī photographer who chooses to use B&W film does well to learn the Zone System, a method for systematic exposure developed years ago by Ansel Adams and Fred Archer. Hasselblad 503CX, Zeiss Planar f3.5 100 mm. Detail of a component on one of the very few operating steam locomotives in the United States, Oregon Rail Heritage Center, Portland, OR. Images made with insufficient exposure display a flatness in the photo. Sufficient exposure leads to richer tonalities in the image which consequently reveal depth and dimensionality.

The camera has excellent quality and feels as well made as a Technika III but not as refined as the later Technika IV and V.Benefits of ample exposure in black and white film photography: Or, let there be light - EMULSIVE Close Search for:Ī film photographer can be confident that development of B&W film, if managed properly, can control ample exposure. As a 4×5 view camera it offers some handy field style front movements including tilt, rise, and shift. Like the Linhofs, the Pressman was designed for press style photography and was offered with a rangefinder as well as a variety of optional hand grips. It is notably lighter than the Technika IV and similar in weight to the Technika III. The Pressman is a metal press 4×5 camera that is similar to a Linhof Technika III. Recently I picked up a Busch Pressman 4×5 camera at Blue Moon Camera in Portland, OR.

The title of this article is the “American” Linhof and since Linhof is German, clearly this needs to shift gears. It was easily twice as heavy as most field 4×5 cameras and three times as heavy as something lightweight like a Tachihara. That translated into a sore back when carrying in the field which is what I did with it most of the time. That camera was stout and by stout I mean you could kill a bear with it. The later model Technika’s only real downfall was the hefty weight.

I loved that Technika, it was so damn well made and the controls were all precision and smooth to operate. Back in the day when I used to shoot a lot of 4×5 film I had a studio mono-rail setup and a Linhof Technika IV.
