Through the Viewfinder photography

Through the Viewfinder photography (TtV) is a photographic technique in which a photograph

A photograph is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of...

Viewfinder
In photography, a viewfinder is what the photographer looks through to compose, and in many cases to focus, the picture. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. Viewfinders are used in many cameras of...

, with the viewfinder plane at 90 degrees to the image plane. The image in a TLR viewfinder is laterally reversed, i.e. it is a mirror image.
Most photographers use a cardboard tube or similar 'contraption' to connect the two cameras. This serves to eliminate stray light and prevent reflections appearing on the viewfinder glass or on the lens of the imaging camera.

TLR models popular among TtV photographers have a brilliant type ('bubble glass') viewfinder. They include the Ansco Anscoflex, Argus 75, Kodak Duaflex and Kodak Brownie.

History

While waist-level viewfinders have been common in box cameras since the beginning of the 20th Century, large viewfinders of the sort that are suitable for ttv photography became popular in the late 1920s and 1930s with medium format
Medium format
Medium format has traditionally referred to a film format in still photography and the related cameras and equipment that use that film. Generally, the term applies to film and digital cameras that record images on media larger than 24 by 36 mm , but smaller than 4 by 5 inches .In digital...

. Similar large, clear square viewfinders were popluar in TLRs and pseudo TLRs until the mid-1960s. These medium format cameras became less popular with the advent of 35mm SLRs and compact cameras in the 1960s and 1970s.

The idea of photographing an image through the viewfinder of such a camera is relatively new, and ttv photography has only really taken off since the advent of digital cameras. Before the advent of digital photography it was necessary to use extension tubes to photograph a close-up object such as a viewfinder, and it was difficult to judge focusing precisely. Both compact digital cameras and digital SLRs are able to focus on close objects without the need for extension tubes, and their autofocus function and digital viewing screen make it easy to focus and judge framing and exposure. They are thus much better suited to this type of photography than most non-digital cameras.

In addition, the popularity of digital photography and of on-line auction sites has led to a big increase in the number lot of older medium format TLRs and pseudo TLRs on the second hand market. Many people find it more convenient to use these cameras for TtV photography than to use them with film.

Equipment and practicalities

The following equipment is required.

1 A "bottom camera" through the viewfinder of which the photograph will be taken. Typically this is a medium formal TLR or pseudo TLR.

2 A "top camera" which will be used to take the photograph. Typically this is a digital SLR or digital compact camera with a macro lens or macro function.

3 A "contraption" to link the two cameras and block out any excess light.

The contraption may be a simple cardboard tube, or an open ended box that fits around the bottom camera.

Post-processing

Post-processing can be done with image editing software. This normally involves cropping the image to a square and straightening it. The cropping is necessary because in most cases the (normally square) viewfinder image covers only about 25- 50% of the area of the (normally rectangular) digital picture.

Additionally some photographers prefer to 'flip' the TtV image so that it is no longer a mirror image, especially if the image contains lettering.

Color and saturation adjustments depend on the taste of the photographer, some photographers prefer to keep such adjustments to a minimum while others prefer more radical adjustments, such as the "Urban Acid" action for the image editing programs Adobe Photoshop
