What is a dslr camera?

Question

I know its digital single lens reflex
but specifically what does it do inside the camera
like what do they mean by reflex

Answer 1

The single lens reflex refers mainly to the pentagram that is hidden inside the camera. The pentagram mirror system relays the image that is seen from the lens into the viewfinder, and it is the exact same image. Other cameras, such as the Point and shoot cameras (disposable cameras, you're average digital camera) do not allow the viewfinder to see exactly what the lens is seeing, the viewfinder simply goes right through the camera and is a different image from what the lens see. The SLR also allows the different settings on the camera to be adjusted (ex. aperture, shutter speed, focus) manually, and some of the newer SLR cameras, such as the Digitals, allow those settings to be automatic. The point and shoot cameras however, do not allow those settings to be adjusted and the camera automatically adjusts the aperture and shutter based on what the lighting situation is. Professional photographers use the SLR cameras for all situations, however, some use models that are based off of cameras used in the 19th century and the early 20th century, as well as they use twins reflex cameras, which contains two lens instead of one.

Answer 2

A digital single-lens reflex camera (digital SLR or DSLR) is a digital camera that uses a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera.



The basic operation of a DSLR is as follows: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at a 90 degree angle. It is then reflected twice by the pentaprism, rectifying it for the photographer's eye. During exposure, the mirror assembly swings upward, the aperture narrows (if set smaller than wide open), and a shutter opens, allowing the lens to project light onto the image sensor. A second shutter then covers the sensor, marking the end of the exposure, and the mirror lowers while the shutter resets. The period that the mirror is flipped up is referred to as "viewfinder blackout". A fast-acting mirror and shutter is preferred so as to not delay an action photo.



All of this happens automatically over a period of milliseconds. Fast cameras do this upwards of 10 times a second.



DSLRs are often preferred by professional still photographers because they allow an accurate preview of framing close to the moment of exposure, and because DSLRs allow the user to choose from a variety of interchangeable lenses. Most DSLRs also have a function that allows accurate preview of depth of field.



Many professionals also prefer DSLRs for their larger sensors compared to most compact digitals. DSLRs have sensors which are generally closer in size to the traditional film formats that many current professionals started out using. These large sensors allow for similar depths of field and picture angle to film formats.



The term DSLR generally refers to cameras that resemble 35mm format cameras, although some medium format cameras are technically DSLRs.

Answer 3

It is an SLR (Manual) camera with a D (Digital) in front of it because when it snaps the shot it is not recorded on standard film, but by a computer that generates the shot taken on a lcd screen in the back of the camera.



SLR is simply a camera that uses a series of mirrors so that teh photographer sees what the lens sees... as opposed to a standard camera where there is a viewfinder where the photographer will see something that is slightly different than what the lens sees.

Answer 4

D stands for digital as opposed to film

SLR is single lens reflex, that is you look through a viewfinder and get the same view as if you could look through the lens

Answer 5

As I comprehend your question, the digital digicam is style of a level and shoot form, while the dslr is extra stepped ahead and commonly resembles the 35mm cameras of many years in the past. between the most wanted advantageous homes of a dslr is the potential to modify lenses. the skinny, %.-of-playing cards sized digital cameras now produce very sturdy pictures, %. quite in a blouse pocket and value lower than $three hundred. A dslr is an finished sized digicam, cumbersome, weighs over a pound and may value $1000 and up for a sturdy one. as long as we photographers proceed to view our pictures on pc reflects and tv video demonstrate instruments, the improved optics and resolutions of severe priced cameras is moot. the version is in effortless words considered in tremendous image prints.

Answer 6

There are 2 types of DSLR cameras. One has a mirror reflecting the image to an eyepiece, that pops out of the way of the sensor when you take a picture, then drops back after (You will notice a slight blink)



the other has a display that sees what the sensor does and you can look at it through your eyepiece -- most offer the option to view on a larger back display as well.



The more expen$ive models allow you to change lenses so that you may take telescopic or wide angle shots. Most all have some sort of zoom lens incorporated, the additional lenses extend this range

Answer 7

Try the new Berries & Paradise Febreze air freshener.

It Eliminates Odors and Freshens.

Have a Merry Christmas and a Happy New Years.

Answer 8

its basically just a better camera because the lens is bigger
