Vintage Cameras is very nostalgic. if you collecting and using Antique and Classic Cameras, make documentaries, and use in Period films. Cameras evolved from the camera obscura, and continued to DSLR cameras. Antique and vintage cameras are valued by collectors for many reasons, from the historical significance of 19th century. The camera should have an internal-zooming lens, since a protruding zoom lens is the most easily damaged part of a compact digital camera. This is Twin Reflex Camera Lens. Vintage TLR Medium Format Twin Lens Reflex Camera. A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. You can key green screen easily and use alpha channel. Double-lens cameras were first developed around 1870, due to the realization that having a second lens alongside the taking lens would mean that one could focus without having to keep swapping the ground glass screen for the plate, reducing the time required for taking a picture. This sort of approach was still used as late as the 1960s, as the Koni-Omegaflex testifies. The TLR camera was thus an evolution. Using a reflex mirror to allow viewing from above also enabled the camera to be held much more steadily than if it were to be held in the hand. The same principle of course applied to SLR cameras, but early SLR cameras caused delays and inconvenience through the need to move the mirror out of the focal plane to allow light to pass to the plate behind it. When this process was automated, the movement of the mirror could cause shake in the camera and blur the image. The London Stereoscopic Co’s “Carlton” model is claimed to have been the first off-the-shelf TLR camera, dating from 1885.
