Viewfinders - the basics
The viewfinder is the optical window you look through to compose the image.
Optical viewfinder
The simplest and most common type in use.
Viewfinder Diopter Adjustment
Several weeks ago, I posted a PhotoTip regarding the need to at least start thinking about digital. Well, in a moment of weakness, I broke down and bought a D100.
Viewfinder Blackout is a problem in single-lens reflex (and also view cameras) where the viewfinder image is lost during the exposure- so the photographer cannot see the exact image at the moment the photograph is taken.

Optical Viewfinder on a Digital SLR Camera (TTL)
The optical viewfinder of a digital SLR shows what the lens will project on the sensor via a mirror and a prism and has therefore no parallax error.

This is what you look through to help point the camera in the right direction when taking a photo. SLR cameras have accurate through the lens viewing so what you see is what the lens sees.

Electronic viewfinders have the following advantages over optical viewfinders: ...
Split circle viewfinders use a pair of tiny prisms set in precise positions in the viewfinder to achieve this effect.
He or she then had you play around with the focus point in the viewfinder showing you how to move it around. When you put the camera down, the focus point that was left active was in the upper right third of the viewfinder.
The brilliant part is that you can accomplish this without even removing your eye from the viewfinder. With the camera up to your eye, there should be a little wheel next to your right index finger. Turn this wheel to adjust your shutter speed.
This image represents what you might see through a non-TTL viewfinder. Although the image looks properly framed, a non-TLL viewfinder does not show what the lens sees. This framing would result in an off center image.

The viewfinder is what you look through to compose the picture. Most often integral to the body, pro cameras have viewfinders that can be switched.
Viewfinder
The viewfinder is the optical system that enables the photographer to see exactly what the lens is projecting on the image sensor or film frame, just prior to the release of the shutter.
Viewfinder Misrepresentation
The other potential problem is caused by viewfinders not showing everything that will appear in the final image. Most viewfinders only show about 90 percent of the actual image.
Viewfinder Magnification Magnification applied to the viewfinder is approximately 0.7X with a 50mm lens. This means objects in the viewfinder look 70% as big as they do with the naked eye.

Vignetting A fall-off in brightness at the edges of an image, slide, or print. Can be caused by poor lens design, using a lens hood not matched to the lens, or attaching too many filters to the front of the lens.

Vignetting
Fall-off in illumination at the edges of an image. This can be caused by poor lens design, using a hood not matched to the lens, or using too many filters at the same time.
VIEWFINDERS- OPTICAL and DIGITAL- Film cameras feature viewfinders that are optical. You look into a little "window" on the back of the camera and there is the approximate picture that will be taken when the shutter release button is pressed.
Viewfinders
There are essentially three types of viewfinder on digital cameras:
Standard real image optical finder
TTL/SLR (Through the lens/single lens reflex)

Viewfinder. A separate window on the camera through which you look to compose images.
White balance. An automatic or manual control that adjusts the brightest part of the scene so it looks white.

Viewfinder. The device in a camera used to frame the image. With an SLR camera, the viewfinder is also used to focus the image if focusing manually.
Viewfinder
A window that is used for checking the scope of the picture. You can check the composition and the focus point of the picture. Two types of viewfinders are available.
Viewfinder
System used for composing and/or focusing the subject being photographed.
Viewfinder
Peer through the viewfinder and check for dust specks, dirt, signs of mildew and fog. Dust can appear as a few spots, many spots, in groups or spread around. Mildew can appear as threads, random cracks, rooted lumps.
The viewfinder
The Diana's is a rangefinder camera and as the viewfinder is not corrected for parallax, what you see in the viewfinder is not exactly the same as what the lens sees.
The viewfinder on our camera is through-the-lens, so we shouldn't have a problem with parallax.
LCD Viewfinder:
We expect to start to see a new generation of LCD viewfinders that will be made using what are known as OLEDs, that is Organic Light Emitting Diodes.
LCD viewfinder
A small screen on the back of a camera that displays what the lens sees. It is used to compose the picture, choose settings, focus and frame an image in macro mode. It is also used to view photos stored on the memory card.
LCD Viewfinders: Some digital cameras come with at least an optical viewfinder--the kind you look through on traditional film cameras--as well as an LCD screen built into the back, which you can use as a viewfinder as well.
100% Viewfinder & voice recording
According to the tech specs, the D2H will feature a 100% viewfinder. Also a huge plus that most of us have missed since the F5.
Optical viewfinders on digital SLR cameras show the scene through the lens (TTL) just as 35mm SLRs do. A mirror bounces light coming through the lens into a prism that directs it out of the viewfinder.
Using a viewfinder
Once you've selected your subject, how do you compose your painting? There are several approaches. One simple way is to use a viewfinder.

Optical Viewfinder: A viewing system that uses no power, but does not always give a true view due to parallax and focus errors.
Viewfinder
The viewfinder shows you the picture you have framed through the camera and lens. Some viewfinders include a grid pattern of lines or a series of dots that would be a grid if connected by lines.
Viewfinder

Viewfinder cameras like the Motormarine IIEX and Nikonos require the shooter to estimate the distance to the subject and then manually adjust it on the lens. Wrong distance estimates result in out-of-focus pictures.

Viewfinder: This is another important part of any camera that some people overlook. There are those who look for fastest shutter speeds, fastest film advance, super fast autofocus, more and more custom functions, and other cool extra stuff.

The viewfinder's light path is directed from the lens via a mirror and prism, so that the photographer can see the image through the lens itself.

Optical viewfinder
A viewfinder system that shows a similar view to that seen by the camera lens ( as on 35mm compact cameras ) Useful because it uses no power, but can cause parallax and focus errors.

-Brightline viewfinder - viewfinder in which the subject is outlined by a bright frame, apparently suspended in space. This may show parallax correction marks, or lines indicating the fields of view of different focal lengths.
-Use the viewfinder instead of the LCD. You know how, a lot of the time, you take pictures by looking at the screen on the back of the camera, holding the camera out in front of you? That's bad in low light.
Look through the viewfinder as though your going to take a photograph.
Press your shutter button half way down and look for a red blinking focal point.
Look through the viewfinder of your camera. If you are outside, you should see an immediate difference in how your surroundings appear. Colors should be more vibrant and reflections on water and leaves should be cut down drastically.
Electronic TTL Viewfinder - This feature found on most digital cameras is basically a tiny LCD with a lens installed in front of it. This allows for more accurate framing.
