Why this camera

A bigger piece of film

Most film cameras of the last century used 35 mm film, with a frame 24 by 36 millimeters. The 503CX uses 120 film, a roll 6 centimeters wide, and makes a square frame 56 millimeters on each side. That's more than three and a half times the area.

A bigger negative needs less enlarging. To make a print 16 inches square, a 6 × 6 negative is enlarged about seven times. A 35 mm negative has to be enlarged about eleven times just to make its long side 16 inches. Less enlargement means finer detail, smaller grain, and smoother gradations from light to dark. That's the main reason professionals carried these heavy, slow cameras: the prints were simply better.

Bigger film also changes the lenses. On 6 × 6, the "normal" lens, the one that sees about the way your eye does, is the 80 mm, because 80 mm is roughly the diagonal of the frame. It sees about what a 45 mm lens sees on 35 mm film. A 50 mm lens is a wide-angle here, and the 150 mm is the classic portrait lens.

The square

Every other camera you've used makes a rectangle, and you turn it on its side for a tall picture. You never turn a Hasselblad. The square frame is the same both ways, which matters with a finder you look down into, since that's very awkward to tip over. You compose once, and decide later, when you print, whether the picture is tall, wide or square.

Many photographers never crop at all, and work with the square as a shape of its own. A rectangle has a direction: it leads the eye along its long side. A square doesn't, so it tends to feel still and balanced. It rewards a subject placed right in the middle, symmetry, and simple, bold shapes, which is why it suits portraits, still lifes, architecture and quiet landscapes. It's harder to use for things that move across the frame.

Looking down

With the standard waist-level finder, you don't raise the camera to your eye. You hold it at your chest, or stand over the tripod, and look down at the picture on a square of ground glass. It's a strange experience at first, and a lovely one. The image glows on the glass like a small painting, the same size as the negative, and you see the whole of it at once, as a picture, rather than peering through a peephole at the world.

Two things take getting used to. The image is reversed left to right, because of the mirror, so you pan "the wrong way" for a roll or two. And the camera sits low, at chest height, which gives a slightly lower viewpoint than you're used to. Photographers have long noticed that people are more relaxed in front of a camera held at the waist, since you can still look at them over the top. The landscape photographer Michael Kenna has said that switching to a waist-level Hasselblad changed the way he composes.

When you need precision, a flip-up magnifier enlarges the center of the screen for focusing. And if you'd rather look straight ahead, a prism finder replaces the hood and gives an upright, unreversed view at eye level.

Four pieces

The 503CX is a system, the idea Victor Hasselblad launched in 1948: a body you build a camera around.

• The lens focuses, sets the aperture, and carries the shutter. Change the lens and you change the shutter too, which is why flash works at every speed on any lens.
• The body holds the mirror and the clockwork that drives everything. No battery, no meter.
• The finder is how you see: the folding waist-level hood, or a prism.
• The magazine holds the film, and comes off mid-roll. Carry two and you can switch between color and black and white, or between a fast film and a slow one, in seconds.

This is why a 1957 lens fits a 1988 body, and why a 2024 digital back fits both. It's also why the camera has so many locks between its parts: with modules that come apart, the order you do things in matters, and the camera enforces it.

Slow on purpose

There's no meter, no autofocus and no motor. You get twelve frames to a roll, and each one costs two to four dollars by the time it's developed and scanned. Everything is done by hand, in order: pull the slide, compose, focus, meter, set the lens, release, wind.

That sounds like a list of drawbacks, and in a sense it is. But photographers who use these cameras talk about what the slowness does to them: they look longer before they press the release, they think about the light, and they make fewer, better pictures. This course is built around that rhythm. On the bench you'll learn it with your hands until it's automatic, and then you'll take it into the field.
