December 3rd, 2009
Today, according to psychologists, more and become more visually inclined. In other words, most of us love to use our eyes!
How we use our eyes?
We use our eyes to see things in our environment. However, over time, humans have found ways to preserve what we see if they are beautiful or not, and what is the use of cameras.
Nowadays, the best sellers in the camera market are called digital SLR cameras.
What is a digital SLR?
SLR stands for Single Lens Reflex. SLR instruments are designed and used by professional photographers. Cameras like these, just use a mirror that reflects light from the eyepiece lens or viewfinder. Thus, a photographer can judge the image or the image will look like. Addition, a digital SLR camera that uses interchangeable lenses. Therefore, this device can be used for long distance telephoto photography or macro photography.
A digital SLR or DSLR camera based on the lenses and mirrors and optical capabilities. However, a DSLR camera uses light sensor chips and digital memory cards instead of film, essentially a computerized version of the camera above.
The following table summarizes the comparison between the PNA and the development and cameras (SLR):
1. SLR and digital SLR use interchangeable lenses for better resolution.
2. Every photo you take with digital SLR cameras and fruits and vegetables generally cleaner and beautiful reproductions.
3. DSLR has a higher speed when approaching and photographs
4. Digital SLR more efficient in low light conditions with ISO speeds. These cameras have fewer granularities.
5. Professional DSLRs provide more energy on the depth of field, light and responsive.
6. Provide digital SLR more immediate, because the use of digital chip or CCD light reflecting the light rays into digital images.
7. SLR and digital SLR cameras costing more than point and shoot cameras.
8. Digital SLR cameras are generally heavier than a point and shoot models.
Some models of digital SLR shows are as follows:
Prosumer models:
• Canon EOS 10D

Like all models and digital computers tend to be cheaper even better with time. In fact, digital cameras, the cameras will eventually migrate to consumers: the ability to take bursts of 10 frames in a few seconds, the fast response time and high-resolution sensors and automatically focus of photos, among others.
The only thing that remains constant is the laws of optics, you can not get the same results of a nail the size of the lens as with larger lenses used by professional users. The fact that people do not have enough money and time remains the same over time.
If you intend to take photography as a profession, firing practice using prosumer models and considers budget and quality of the lenses before saying: “Big Cheese”!
