SLR Digital Camera Basics
Nowadays, according to psychologists, more and more people are getting visually
inclined. In other words, most of us love to use our eyes!
So what do we use our eyes for?
We use our eyes to view things in our environment. However, throughout time, man
has devised ways to preserve the things we see, whether they are just remembered,
sketched, drawn, or painted, and one other way is by using cameras. Today they are
digital cameras.
These days, the biggest sellers in the camera market are the digital SLR cameras.
So what is a digital SLR camera?
SLR is an acronym for Single Lens Reflex. SLR cameras these digital cameras where
made for and used by professional photographers. Cameras such as these, similarly,
make use of mirrors that reflects light entering the lens up into the eye piece or
the viewfinder. Thus, a photographer can gauge how the image or picture will look
like. Moreover, a SLR camera uses lenses that are interchangeable. Hence, this
camera can be used for long distance telephoto photography or close-up macro
photography.
A normal SLR camera is dependent on lenses and mirror and their optical
capabilities. However a DSLR camera uses light sensor chips and digital memory
cards instead of films, basically a computerized version of the above mentioned
camera.
The following summarizes the comparison between DSLR and point and click cameras
(SLRs):
1 Both use interchangeable lenses for better resolution.
2. Any picture you take using SLRs where usually crisper, cleaner and fine upon
reproduction. However this has changed with the modern digital camera as they now
produce pictures using millions of mega pixels to make even better pictures than
the normal SLR.
3. DSLRs have a higher speed when it comes to focusing and taking pictures
4. DSLRs perform better at low lighting conditions by using ISO speeds. These
cameras have lesser granularity.
5. DSLRS provide more professional power over depth of field, light, and
responsiveness.
6. DSLRs provide a more immediate feedback as they use digital chips or light
sensing CCDs that translate incoming light rays into digital pictures.
7. DSLRs and SLRs cost more than point and click cameras.
8. DSLRs and SLRs are usually heavier than some point and click models.
Some sample DSLR models are listed below:
Compact models:
• Canon EOS 10D
• Canon EOS Digital Rebel XT
• Nikon D50
• Nikon D70s
• Pentax *ist DS
Professional Models:
• Canon EOS 1D Mark II
• Canon EOS 20D
• Fuji Finepix S3 Pro
• Nikon D2x
Who actually wants DSLRs? Anyone wants to have crisper and clearer pictures—be it
a hobbyist or a professional photographer can opt for a DSLR model. Anyone who
will not bother carrying bigger cameras on trips in order to bring back topnotch
photos can make use of DSLRs.
Like all electronic and computerized gadgets, digital models tend to get cheaper
yet better over time. For sure, DSLRs will eventually migrate down to consumer
cameras: ability to take bursts of 10 frames in a few seconds, quick response
time, higher resolution image sensors, and accurate auto-focus, among others.
The only thing that will remain constant are the laws of optics—you will not get
the same results from a finger-nail sized lens as with larger lenses used by
professional users. Also the fact that people do not have enough money all the
time remains the same through time.
If you plan to take photography as a profession, practice shooting some shots
using compact models and consider budget and quality of lenses before you say,
“Big Cheese”!
