Using a viewfinder properly provides an inherently more stable hold than holding the camera at arms length to look at the LCD screen. This allows one to use a slower shutter speed without getting camera motion blur. A slower shutter speed produces an image with less noisiness.
The viewfinder has some advantages: The sun can make LCD almost useless. Holding the camera against your head instead of in front of your wihout extra support of the head is less stable. It is much faster to poit at the subject (and to find it in the view) if the camera is on your eye, than if it is 30cm in front of it.
DSLRs have an optical TTL ( through the lens) viewfinder , which allows you to look through the lens and see precisely what the lens projects onto the sensor. (Sometimes on compact cameras , the viewfinder is parallel to the camera’s lens so that what you see is different from what the lens projects onto the sensor.)
Electronic viewfinders use a tiny electronic display much like the larger LCD screen on the back of all cameras, whereas optical viewfinders use mirrors and prisms to represent the view of a scene.
Viewfinder , camera component that shows the photographer the area of the subject that will be included in a photograph. In modern cameras it usually is part of a direct visual- or range-finder focusing system and may also be used to display exposure settings or meter information.
The diopter is a small lens in your camera’s viewfinder . If your eyesight is good and you are using a camera that’s had the diopter adjusted, you will see a blurry image in the viewfinder . You will need to adjust the diopter to correct this so you can see a sharp image.
By adding an external LCD viewfinder , you can hold the camera right up to your eye in a way that feels more natural for shooting video with an SLR-shaped camera . In bright sunlight, even the best LCD view screen is as washed-out looking as the cheapest point and shoot—and incredibly difficult to see.
The display does not automatically switch to the viewfinder . On the camera, press the MENU button. Select Custom Settings. Select FINDER/ MONITOR . Select Viewfinder . NOTE: Setting the FINDER/ MONITOR setting to Viewfinder switches the display between the Electronic Viewfinder and the LCD screen by pushing up or down the pop-up finder.
Many professional photographers use high-end Canon or Nikon DSLRs, such as a Canon EOS 1DX Mark II or a Nikon D5.
Shutter speed is a measurement of the time the shutter is open, shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc.
Most people will use their most dominant eye in the viewfinder ; usually right handed people will use their right eye . So it’s safe to assume that you’re part of most-people (statistically), and you use your right eye .
When talking about digital cameras the term ‘ live view’ refers to a mode which allows a photographer to view the photographic sensor output in almost realtime on the camera’s LCD screen. In live view mode the photographer sees what the lens is seeing, including the effects of any changes in exposure settings.
