DSLR Digital Camera

DSLR Digital Camera

DSLR stands for “Digital Single Lens Reflex”. In simple language, a DSLR digital camera is a camera that uses a mirror mechanism to either reflect light from the camera lens to an optical viewfinder or let light fully pass onto the image sensor (which captures the image) by moving the mirror out of the way. Although single lens reflex cameras have been available in various shapes and forms since the 19th century with film as the recording medium. Compared to point-and-shoot and phone cameras, DSLR cameras typically use interchangeable lenses. The lenses typically used on DSLRs have a wider range of apertures available to them as well, so let's learn more about the features which you'll typically be able to find on a DSLR digital camera. 

DSLR Camera Features – So you may be wondering what makes a camera a DSLR digital camera. Typically, there are a few components that class a camera as a DSLR digital camera and we're going to name them:

1. Lens

2. Reflex Mirror

3. Shutter

4. Image Sensor

5. Focusing Screen

6. Condenser Lens

7. Pentaprism 

8. Viewfinder

DSLR Traits - When you look through a DSLR viewfinder / eyepiece on the back of the camera, whatever you see is passed through the lens attached to the camera, which means that you could be looking at exactly what you are going to capture. Light from the scene you are attempting to capture passes through the lens into a reflex mirror that sits at a 45-degree angle inside the camera chamber, which then forwards the light vertically to an optical element called a “pentaprism”. The pentaprism then converts the vertical light to horizontal by redirecting the light through two separate mirrors, right into the viewfinder.

When you take a picture, the reflex mirror swings upwards, blocking the vertical pathway and letting the light directly through. Then, the shutter opens up and the light reaches the image sensor. The shutter remains open for as long as needed for the image sensor to record the image, then the shutter closes and the reflex mirror drops back to the 45-degree angle to continue redirecting the light into the viewfinder. Next, a lot of complicated image processing happens on the camera. The camera processor takes the information from the image sensor, converts it into an appropriate format, then writes it into a memory card. The whole process takes very little time and some professional DSLRs can do this 11+ times in one second!

DSLR & SLR – You may be wondering what the difference is between a DSLR digital camera and an SLR camera, so don't worry if you're not too sure what the difference is between the two! We'll clear that up really quickly... So, "SLR" actually refers to a camera with a Single Lens and a Reflex mirror to bend the light path to the optical viewfinder for framing. A DSLR is a Digital SLR, meaning it has a digital sensor to record images. Digital SLRs have may advantages compared to their film counter-parts.

DSLR or SLR? - The burning question is "which one of these cameras are better"? Technically DSLRs and SLRs are the same thing, except for the media the image is recorded upon. Both are Single Lens Reflex cameras which take interchangeable lenses and have a mirror, pentaprism and optical viewfinder, so it's really a personal call which camera you want to use and what your needs are for using it. Although typically wedding photographers do tend to use DSLR cameras.
