A twin-lens reflex camera is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens" (the lens that takes the picture), while the other is used for the viewfinder system, which is usually viewed from above at waist level.


In addition to the objective, the viewfinder consists of a 45-degree mirror , a matte focusing screen at the top of the camera, and a pop-up hood surrounding it. The two objectives are connected, so that the focus shown on the focusing screen will be exactly the same as on the film. However, many inexpensive "pseudo" TLRs are fixed-focus models. Most TLRs use leaf shutters with shutter speeds up to 1/500th sec with a B setting

For instance a slow shutter-speed often results in a blurred image as the slight shudder of the shutter itself, or the motion caused to the whole camera by the index pressing on the shutter-release button create vibrations that are faster than the shutter itself; this will cause the appearance of the objects in the view-finder and on the photographs having moved when in fact it is the camera that moved]]> 2016-11-15 14:44:52 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/137738054 aperture elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/137742202 The aperture stop of a photographic lens can be adjusted to control the amount of light reaching the film or image sensor. In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light. Typically, a fast shutter will require a larger aperture to ensure sufficient light exposure, and a slow shutter will require a smaller aperture to avoid excessive exposure.]]> 2016-11-15 14:52:41 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/137742202 memory and storage elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/138676168 JPEG (Joint Photographic Experts Groups)

The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”.]]> 2016-11-22 14:28:19 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/139359150 twin lens reflex elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/140506490 2016-11-29 14:35:42 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/140506490 how a camera works. elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144044120 Digital cameras look very much like ordinary film cameras but they work in a completely different way. When you press the button to take a photograph with a digital camera, an aperture opens at the front of the camera and light streams in through the lens. So far, it's just the same as a film camera.]]> 2016-12-16 13:51:05 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/144044120 manual modes elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144045746 Manual mode allows you to set both your aperture and shutter speed separately, without the camera automatically changing the other to suit. With this in mind, you can be more creative with your shots. For example, you can photograph a beach landscape keeping the aperture high (for example f/22) so everything is in focus, yet at the same time set a slow shutter speed to create dreamy, slow motion waves. ]]> 2016-12-16 13:57:31 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/144045746 automatic mode elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144046711 Automatic mode is a mode in a digital camera where the camera's software fully controls all aspects of the photograph, from the shutter speed to the aperture setting to the focus.]]> 2016-12-16 14:01:34 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/144046711 viewfinder. elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144049190 In photography, a viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture.

The different focal lengths are grouped into categories for different types of lenses.

It does so by converting the variable attenuation of light waves (as they pass through or reflect off objects) into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, digital imaging tends to replace analog imaging.

Since the resolution is 300 dpi, it means that each inch is 300 pixels across. As the image is 8 inches wide that means there are 2,400 pixels in width (8 x 300). Likewise, as the image is 12 inches long, the image is 3,600 pixels in length (12 x 300). To get the total we multiply the breadth by the length and the answer is 8,640,000 pixels (2400 x 3600)]]> 2016-12-16 14:39:32 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/144057851 hand held elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144058725 Hand-held camera or hand-held shooting is a film making and video production technique in which a camera is held in the camera operator's hands as opposed to being mounted on a tripod or other base]]> 2016-12-16 14:42:20 UTC https://padlet.com/elaacir1/x9qdgm936a9b/wish/144058725 white balance elaacir1 https://padlet.com/elaacir1/x9qdgm936a9b/wish/144060577 White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo.
