DSLR Cameras are increasingly becoming in the reach of the average photographer as prices fall and as manufacturers develop more user friendly models
WHY BUY A DSLR CAMERA:
SLR cameras have two primary benefits compared to combined lens and body cameras:
1. An SLR can accept multiple detachable lenses, each of which is designed for a specific purpose. Depending on their photographic needs, owners can attach wide-angle, portrait, telephoto, and other specialty lenses. These detachable lenses tend to have higher-quality optics, which make for sharper photos.
2. An SLR's viewfinder lets the owner see through the same lens as is used to take the image. Most attached-lens cameras use a viewfinder system, which provides the photographer with a separate window to compose and focus the image. Because of the different vantage point provided by a non-SLR viewfinder, the image the photographer sees can be different than the image that is recorded as the final photo. For serious photographers, an SLR's through-the-lens viewfinder provides a truer perspective.
OTHER USEFUL FEATURES:
*SPEED
So why are some compact cameras so slow and digital SLRs so fast? It's electronics vs. mechanics.
There's a device called a shutter that sits in front of the digital SLR sensor, blocking it from light.
When you take a photo, the shutter (made up of two curtains) opens and closes.
This is different from a compact camera, where there is no shutter mechanism. In compact cameras, the sensor is electronically activated every time you take a photo.
The advantage of the mechanical solution is that it is instantaneous: you press the shutter button and the shutter snaps open.
High Quality in Low-Light
One clear advantage of digital SLR cameras is that they're able to capture photos even when there's not a lot of ambient light.
Digital SLRs are able to take photos when there's little available light because of a feature called ISO: it makes the digital sensor more sensitive to light.
While several compact digital cameras will also let you change the ISO of the camera, there is one key difference.
As you increase the ISO (and increase the camera's sensitivity to light) you also add grain or "noise" to the image.
The advantage of digital SLR cameras when it comes to ISO is that even at high ISO settings they produce very little noise. I can't say the same about compact cameras.
You Have Control
With a digital SLR, you have complete control over every photo you take, and don't have to rely on the camera to make choices for you.
Even if you're not ready to make the jump to a fully manual camera, don't be frightened off.
Every digital SLR camera lets you use an automatic setting, and provides you with intermediate steps that offer increasing levels of control over your images.
In this world of raging media, it is important for bloggers to own a camera to share their points of view by showing them to others through images or videos.
