Later SLRs had a mechanism which flipped the mirror out of the way when the shutter button was pressed, followed immediately by the shutter opening. When ready to take the picture, the mirror was pivoted out of the way (without moving the camera). Early SLRs were plate cameras, with a mechanism to insert a mirror between the lens and the film which reflected the light upwards, where it could be seen at waist level on a ground glass screen. Single-lens reflex (SLR) cameras viewed the scene through the taking lens. Cameras with interchangeable lenses had to indicate the field of view of each lens in the viewfinder more usually, interchangeable viewfinders to match the lenses were used. Some sophisticated 20th century cameras with direct viewfinders had coincidence (split-image) rangefinders, initially with separate windows from the viewfinder, later integrated with it they were called rangefinder cameras. Viewfinders often show lines to indicate the edge of the region which would be included in the photograph. The error varies with distance, being negligible for distant scenes, and very large for close-ups. Parallax error results from the viewfinder being offset from the lens axis, to point above and usually to one side of the lens. A declining minority of point and shoot cameras use them. A zoom camera usually zooms its finder in sync with its lens, one exception being rangefinder cameras.īefore the development of microelectronics and electronic display devices, only optical viewfinders existed.ĭirect viewfinders are essentially miniature Galilean telescopes the viewer's eye was placed at the back, and the scene viewed through the viewfinder optics. Viewfinders are used in many cameras of different types: still and movie, film, analog and digital. Most viewfinders are separate, and suffer parallax, while the single-lens reflex camera lets the viewfinder use the main optical system. In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture.

Australian artist Joel Adler designed this periscope-like sculpture titled Viewfinder. For more about the artist’s work, visit his website or follow him on Instagram.

Due to the added height and increased wind loading, another three tons of ballast material was needed to stabilize the structure. At its new location, the sculpture is positioned on a much higher cliff and offers an even more expansive view of the surf below. Originally completed for Sculpture by the Sea: Bondi in 2019, Viewfinder has since been moved to its permanent location in Lighthouse Reserve, Woollahra (a suburb of Sydney, Australia). Viewfinder is completely analog-there are no microphones, no electricity, and no screens (except for the ones filming it from the path). Sometimes all it takes is a clean mirror and reflected sound to trick the brain. “I have heard many comments about Viewfinder referencing a ‘digital'/'projected'/'TV' element inside the sculpture and the ‘amplification' of the sounds below. “Sometimes the most ‘real' things feel unreal,” Alder shared on Instagram. The concrete and steel sculpture-slightly Brutalist in its design-offers a somewhat surreal interface whereby people might experience that bit of nature firsthand all without ever making direct contact with it. Reflecting both light and the sound of the churning waves, it’s as if Viewfinder transports the viewer from the cliff’s summit directly to its base hundreds of feet below. It's a sight previously impossible to observe from such a vantage point.įor the design, Adler drew his inspiration from historic naval interfaces as well as the human-nature interaction. Jutting out several feet over the edge of a cliff, the angular structure reflects a breathtaking view of the magnificent waves crashing below. His sculpture titled Viewfinder-a 440-pound mirror cantilevered by six tons of concrete and steel-imitates the function of a periscope. Working in a variety of mediums, he creates site-specific sculptures, installations, and interactive objects that offer new ways to experience the surrounding environment. Australian artist and industrial designer Joel Adler centers his work around the experience of the viewer.
