Today, according to psychologists, people are increasingly inclined visually. In other words, love most of us use our eyes!

How we use our eyes?

We use the eyes to see things from our environment. Over time, however, man has developed ways of keeping the things we see, if they are good or not, and one does not kill you, take pictures and video.
These days, the best sellers in the market cameras are cameras that are called digital SLRs.

Anything that is a reflex?

SLR stands for Single Lens Reflex. SLRs are the tools made and used by professional photographers. Cameras like these, as well as take advantage of a mirror that reflects light from the lens to the eye piece or the viewfinder. This graph can be measured as the image or the image will look like. In addition, the SLR camera uses lenses that are interchangeable. So, this camera can be used for long-distance telecommunications photography or close-up macro photography.
A digital SLR or a digital SLR camera lenses and mirrors dependent and optical capabilities. However, a digital SLR camera uses light sensor chips and digital memory cards instead of film, essentially a computerized version of the anterior chamber.

The following table summarizes the comparison between digital SLRs and point and shoot cameras (SLR):

DSLR and SLR cameras use interchangeable lenses for a better solution.
Any photo you take with the SLR and DSLR cameras is the reproduction in general, sharper, cleaner and finer.
DSLRs have a higher speed when it comes to focus and take pictures
DSLRs do better in low light conditions using ISO speeds. These cameras have less precision.
Professional DSLR to provide more depth of field, light, and responsiveness.
DSLRs provide a more immediate feedback as they use digital chips or light sensing CCD that translate the incoming light rays into digital images.
SLR digital and more expensive than point and shoot cameras.
Digital SLR cameras and is usually heavier than some models of point-and-shoot.

Some examples of digital SLR models are:

Prosumer models:

Pentax * ist DS
Professional models:
Canon EOS 1D Mark II
Canon EOS 20D
Fuji FinePix S3 Pro
Nikon D2X
Canon EOS 10D
Canon EOS Digital Rebel XT
Nikon D50
Nikon D70s

Who really wants to DSLR? Everyone wants to be sharper, clearer images, it is amateur or professional photographer, they can select a model DSLR. Who does not bother to pursue more cameras travel back and forth between the images can take advantage of high-level digital SLR.

Like all electronic and computerized gadgets, digital models usually less expensive even better with time. Of course, then move to DSLR cameras consumer credit: the ability to gusts of 10 frames in a few seconds, a fast response time, the higher resolution image sensor, and accurate focusing, for example.

The only thing that remains constant is the laws of optics, you will not get the same results from a lens of nails with large companies, such as lenses used by professionals. Also the fact that people do not have enough money and time remains the same over time.

If you are going to take a picture of the profession, practice shooting some shots with the prosumer models and consider budget and quality of the lenses before saying, "Big Cheese"!
