Why do you see a matte image when viewing through your viewfinder on a slr camera?
== == == == In an SLR (Single Lens Reflex) camera, the viewfinder is not a direct view of the scene in front of the camera. The image from the lens is reflected off of a mirror and focused onto a piece of ground glass. It is this ground glass that is viewed through the pentaprism and viewfinder. Images on ground glass are matte images.
**************
True enough, but when the camera is not an SLR (such as some medium and large format cameras) a matte screen is still used. The question is why do you see a matte image, not "how does the reflex system work?". The matte screen as a focusing aid was introduced long ago because it is easier to focus on a glass surface when it has a matte finish than if it is smooth like a window pane. Most manual focus cameras these days (SLR or not) that are medium format or smaller, also incorporate a center spot that appears split (horizontally, vertically or diagonally depending on the manufacturer) as the central focus aid. This is often surrounded by a concentric ring that appears diamond-like or "prismatic" which is the Fresnel lens portion. The matte screen makes up the rest. Thus, the manufacturer attempts to please everyone by providing 3 focus aids. Sometimes, longer than normal focal length lenses make the split portion difficult or impossible to use, so one has to rely on the Fresnel portion or the matte screen. Many landscape photographers prefer to have only a matte screen, and will substitue optional screens when possible. When it comes to large format cameras, the matte screen is the only option as far as I know.

What is the basic principle of operation of a still camera?
To successfully operate a still camera, you will need to view the image you want to view through the viewfinder window. Then you simply press the button to take a picture.
What are the three basic elements of the video camera?
1) The Diaphragme (iris)- Limits the amount of light that goes into the camera. 2) The Lens- Light passes through the lens to form an inverted image in the camera. 3) Charge Coupled Device (CCD)- Absorbs light and emits electrical signals needed to produce a digital image.
Why is an SLR camera better than the automatic?
SLR or single lens reflex refers to a particular type of camera in which the image and the viewfinder are both taken from one lens. effectively WYSIWYG. auto focus auto exposure modes have been available in SLR cameras for a very long time thus making them "automatic." As a side note an SLR need not have exchangeable lenses to be an SLR nor are all cameras with exchangeable lenses SLR's. The primary advantage of SLR's is the fact that the image in the viewfinder is pretty much the image that you get when you release the shutter.
What does a mirror do in a camera?
The mirror is part of the viewing/focusing mechanism. In an SLR with a pentaprism or similar means of getting the light from the lens to the eyepiece, the light coming through the lens has to be redirected vertically up, and then redirected horizontally out, to the back of the camera. The mirror is used as the first means of diversion because it is directly behind the lens and also may provide some or all of the blockage between the lens and the film or sensor. (some SLRs may have no focal plane shutter just a mirror, that flips up for the amount of time that the shutter speed is set). In a rangefinder camera if it is a mirror assembly then the mirror picks up a second image through a second port that is then redirected by the mirror to the main eyepiece viewer, and focusing is based on adjusting the secondary image that is superimposed on the main eyepiece viewer. SLRs can have a combination of such a "split image" as well as soft-to-sharp focus system but again it is direct through the lens.
What is the difference between an SLR digital camera and a compact digital with manual exposure control?
Principle difference is "through-the-lens" framing and focus. Naturally you can control depth of field, light levels, focus, etc with both units, but with the SLR you see these changes before you take the picture. There are advantages and disadvantages to both types of camera: The compact will be smaller, lighter and quieter; the SLR has a mirror that flips up when the shutter is released to switch light from the viewfinder to the sensor. This makes a noise, the compact doesn't need the mirror so they can be pretty much silent. On the other hand, apart from the Leica M8, compact digitals do not have interchangeable lenses. Being able to change lenses is a big advantage, you can also see the affects of any filters by looking through the viewfinder. In most cases a digital SLR will have better quality optics, sensor and light metering than a compact digital - although there are exceptions; the M8 would give any DSLR a run for its money for quality - but it does cost £3000 for the body alone! ---- 9-07-2006 The SENSOR ! The sensor is what holds the image you took. On most point and shoot digital cameras, the sensor is a certain size...... On a digital SLR, the sensor is BIGGER. ---- The Sensor is not only larger, but is much more sensitive .
What is the eye device you look in through on the camera to compost your image?

Why DSLR is called single lens?
A DSLR, or Digital Single-Lens Reflex camera, is called "single lens" because it uses a single lens for both capturing the image and for viewing through the viewfinder. The camera employs a mirror mechanism that reflects light coming through the lens up into an optical viewfinder, allowing the photographer to see exactly what the lens sees. This design contrasts with other camera types that may use multiple lenses or electronic displays for viewing.
What type of image viewfinder does an SLR camera have?
You can either use the digital image finder to line up your shot on your camera or the optical viewfinder eyepiece that is made of glass, mirrors and lenses.
What is the difference between a DSLR and an SLR camera?
A DSLR camera has a digital sensor to capture images, while an SLR camera uses film. Additionally, a DSLR allows you to view the image through an electronic display, whereas an SLR uses a mirror system to reflect the image through the viewfinder.
What is the basic principle of operation of a still camera?
To successfully operate a still camera, you will need to view the image you want to view through the viewfinder window. Then you simply press the button to take a picture.
What are the differences between using a viewfinder and live view when capturing images with a camera?
When capturing images with a camera, using a viewfinder allows you to frame the shot by looking through the camera's optical system, while live view shows the image on the camera's screen. Viewfinder is more traditional and offers a direct view of the scene, while live view can be more convenient for composing shots from different angles or in difficult lighting conditions.
What are the differences between live view and viewfinder when it comes to capturing images?
Live view and viewfinder are two different ways to frame and capture images with a camera. Live view allows you to see a digital preview of the image on the camera's screen before taking the shot, while the viewfinder is an optical window that shows you the scene directly through the camera's lens. Live view can be helpful for composing shots on a screen, while the viewfinder provides a more direct and immediate view of the scene.
Is a camera a reflection or a refraction and how?
A camera relies on both reflection and refraction to capture images. The lens of the camera refracts light to focus it onto the image sensor, creating a clear image. The mirror inside the camera reflects light to direct it towards the viewfinder or the image sensor.
How to take a picture on a camera: Could you explain the process of capturing an image using a camera?
To take a picture with a camera, first, turn on the camera and frame your shot by looking through the viewfinder or screen. Press the shutter button halfway to focus, then fully press it to capture the image. Review the picture on the screen to make sure it's what you want.
What is the difference between point and shoot camera and DSLR camera?
A single lens reflex (SLR) is a camera that uses the same set of lenses to both focus the image on the CCD (digital) and enable the photographer to frame the picture. That is to say, when you look through the viewfinder of a DSLR you are looking directly at the object through the main lens. You are not looking at the digitally re-created picture of the object or through some other lens that is off-center of the main lens. A point-and-shoot camera will have some other mechanism for framing the picture.
Definition of Digital Camera?
A camera that encodes an image digitally in pixels and stores it for later viewing and modification.
What is a film SLR?
A SLR camera is a camera in which the viewfinder sees directly through the lens via a mirror. Most point and shoot cameras have an additional lens that you look through which is offset from the lens that takes the picture. This means the photographer sees a slightly different image than the camera records. A film SLR records the image on negatives rather than in a digital format.
