Digital SLR Camera Overview
SLR cameras allow for more accurate composition and colour balance since what you see through the viewfinder will be what you get in the final picture.
Traditional SLR cameras used film but today's digital SLR cameras allow for digital capture so that you can review your images instantly.
DSLR cameras often have image sensors of much larger size and often higher quality, offering lower noise, which is useful in low light. Although mirrorless digital cameras with APS C and full frame sensors exist, most full frame and medium format sized image sensors are still seen in DSLR designs.
DSLR cameras are highly valued by military photographers because of their resolution, sensitivity, versatility in the field, availability of a wide variety of objective lenses and because they allow an accurate preview of framing close to the moment of exposure.
Many photographers also prefer dSLRs for their larger sensors compared to most compact digital cameras, now available with image sensors the same size as traditional film formats. These large sensors allow for similar field of view values to film formats, as well as their comparable sensitivity.
The SLR camera price can differ from store to store. There are the best brands with great prices and discounts. You will find the best SLR camera with the best features in the most popular brands. The Nikon, Canon, Pentax are some of the popular brands in India. The SLR camera price ranges from $ 299 to a more expensive range of SLR camera.
Most SLR cameras permit upright and laterally correct viewing through use of a roof pentaprism situated in the optical path between the reflex mirror and viewfinder.
Light, which comes both horizontally and vertically inverted after passing through the lens, is reflected upwards by the reflex mirror, into the pentaprism where it is reflected several times to correct the inversions caused by the lens, and align the image with the viewfinder.
When the shutter is released, the mirror moves out of the light path, and the light shines directly onto the film (or in the case of a DSLR, the CCD or CMOS imaging sensor). The Canon Pellix film camera was an exception to the moving mirror system, wherein the mirror was a fixed beamsplitting pellicle.
Digital SLR cameras, along with most other digital cameras, generally have a mode dial to access standard camera settings or automatic scene mode settings. Sometimes called a "PASM" dial, they typically provide as minimum Program, Aperture priority, Shutter priority, and full Manual modes. Scene modes vary and are inherently less customisable. They often include full auto, landscape, portrait, action, macro, and night modes, among others.
Professional DSLRs seldom contain automatic scene modes as professionals do not require these. Digital SLR cameras can be bought as kits or camera body only, where you have to buy the lens separately. The SLR camera kit is popular, and adequate, for photography beginners; and the more experienced person will usually know what kind of lens to get.
The photography novice can find a great deal of satisfaction with the kit lens. If you do some pricing you'll see that the kits go for much less than making two different purchases for body and lens. That piece of helpful info can save you money when you're talking to a sales rep just in case. Another potential situation is shopping on the web; so just remember that SLR camera kits are available and can be bought. It doesn't matter if you buy offline or online, be very sure of what you're getting with the price you're paying.
Although SLR cameras are more expensive than the regular digital cameras but they provide the photographers the facility to obtain a better picture quality and ultimate output with their superior technology.
Speed DSLR cameras are much quicker than the typical digital camera. You'll notice reduced shutter lag (the delay between pushing the button and actually capturing the image) with your DSLR. If you'll be shooting lots of action shots then you'll likely want a faster model.
