(When I set focus by looking at the ground glass and moving the lens focus ring for the first time in 1967 with my father’s Pentax Spotmatic, it was a revelation!) When the shutter is pressed there is a blackout, but on most modern SLRs the mirror has an instant return, which is much better. The modern SLR/DSLR (digital SLR) mirror sends the light up into a pentaprism that sends the image, right side up and correct left to right, out the viewfinder to the eye. This camera created the path to the introduction of the sensational Nikon F in 1959, which firmly established the 35mm SLR as the prevailing camera for amateur and professional photographers alike for decades. ![]() In 1938, Germany’s Practica made the Exakta, the first 35mm SLR camera. It may surprise you that such a camera was available in the ’teens, and by the 1930s, the inimitable Lucius Beebe was using the Graflex Model B camera - a 4″x5″ sheet film SLR beast of wood, leather, steel, and glass - to make the stunning wedgies in his books. The well-known medium-format Hasselblad works exactly the same way. You would not see an image again until you manually lowered the mirror. Second, when you tripped the shutter, the camera viewfinder would black out. First, the image was flipped left to right, which makes composition a challenge. When you press the shutter, the mirror flips up and out of the way of the film. This not only allows viewing of what the camera sees, but allows focus to be set as well by moving the lens back and forth until the image is clear. All the light from the lens is sent up to a glass plate viewfinder. The basic principle of the SLR has a mirror placed at a 45-degree angle behind the lens and before the film. However, with the invention of the SLR in the 20th century, the photographer had for the first time the ability to see exactly what the camera was seeing right up to the moment of exposure. Since their invention in the 1830s, cameras have required the user to either look through the rear of the camera before inserting the emulsion or use a viewfinder that could only approximate what the camera was seeing. To understand how differently, let’s look a little into the history of cameras. What is happening now in the camera world is that we are on the cusp of an evolution to the next basic form, one that works a bit differently. Almost as old as railroading itself, it has proven mutable from the first wooden boxes and glass negatives, to folding cameras with roll film, to the modern 35mm single lens reflex camera, to today’s digital SLR models. ![]() Just like our beloved trains, the camera has also evolved. As much as we revel in examining the change of the railroad locomotive from the earliest steam to the latest diesel, I wager the favorite tool that we use to interact with and record our railfan experience gets far less attention. ![]() It cannot be stopped, and as much as we miss the familiar and distrust the new, in the long run advancing technology serves us and makes our lives better.Īs railfans, we pursue our passion for railroading in many ways. Ever since the invention of the wheel itself, technology has inexorably evolved. It forever changed the world in which we live a most gracious gift to civilization from its first developers in the United Kingdom. When the first commercial railways were constructed 200 years ago, the application of metal wheels on metal rails was a great leap forward from millennia-old methods of muscle, wind, and water power. Unique curve tools, adjustment re-ordering and layering, and large precise controls let you do things you simply can’t do in other popular software.įollowing are some ways CameraBag is perfect for specific groups of users.Camera Bag: What’s The Deal With Mirrorless Cameras?
