Large format 4x5

A 4x5 sheet is 4 inches by 5 inches, about fifteen times the area of a 35mm frame. Grain stops being visible at any normal print size, and the amount of fine detail the negative holds is the first thing a reader notices. The frame is a 4:5 rectangle, close to a sheet of paper and usually stood upright.

The second thing is the geometry. A view camera moves its front and its back independently, so the plane of focus does not have to sit parallel to the film. A landscape can run sharp from the near rock to the far ridge, and a tall building can stand with straight vertical lines. Both are decided in the camera, before the exposure, and neither is a correction made afterwards.

Name the format and the sheet: large format 4x5, 4 inch by 5 inch sheet film. Say no visible grain, because on this format the absence is the look and a model will add grain unless you stop it.

Say what the movements do, in plain terms. For a landscape, ask for a tilted plane of focus that runs front to back. For a building, ask for parallel vertical lines with no convergence. The words tilt and shift mean little to a model on their own, so describe the result.

Choose the depth of field on purpose, because this format can go either way. Wide open, a 4x5 holds very little: a portrait can have the eyes sharp and the ears already soft. Stopped down with a tilt, the same camera holds everything from the foreground to the horizon. State which of the two you want.

Use it for a landscape that has to be sharp everywhere, for a building that has to stand straight, for a still life with fine texture, and for a portrait that has to survive a wall sized print.

Leave it alone for anything that moves. The camera sits on a tripod, one sheet holds one picture, and the working pace shows in the result. A 4x5 portrait of a running child is a contradiction the prompt cannot resolve.

Cinema publishes Tilt-Shift at /techniques/cinema/ as a lens, and Deep Focus as a focus choice. This entry is the camera that does both by moving its own front and back standards, and it does them on a negative fifteen times the area of 35mm. The cinema lens entry fakes a miniature or corrects a line. This one describes the whole camera that gave those effects their names.

Cinema also publishes Film Grain at /techniques/cinema/ as its own entry. Large format is the format that has none, so a 4x5 prompt usually has to say so, and has to say it early.

Medium format 6x6 is the step below: smoother than 35mm, still handheld, still square. Large format 4x5 gives up the hand and the square, and buys detail and geometry with what it gives up.

Graflex sold the Speed Graphic from 1912, and it was the standard American press camera until the middle 1950s, when 35mm took the work away from it. Group f/64 formed in San Francisco in 1932 and named itself after a small aperture, because sharpness front to back was the whole programme. Sinar and Linhof kept the studio and the architectural work on 4x5 through to the 1990s. Polaroid Type 55 gave a print and a usable negative from 1961 until 2008, and the ragged black edge of that negative is the rebate people now ask a model for by name.

The picture comes back with grain, because photographic prompts carry grain by habit. Say no visible grain and name 4x5 sheet film, not film on its own.

The building leans back. Say parallel vertical lines, say the camera back stays parallel to the front of the building, and put the ban on converging verticals in the same line.
