Step by Step Method on How a DSLR Camera Works

I just wrote this article for those people who are wondering how a DSLR camera works and why it is more superior to a typical digital camera (point-and-shoot camera.) In this article, I listed the things that made the DSLR unique. HereĀ is a guide on how to use your DSLR camera.


A picture captured using a DSLR camera begins on the lens. DSLR lens is a variety of sub-lenses known as elements. Each lens refines and centers light to produce a high quality photograph. Lenses on Digital SLRs may be replaced for several functions. Wide angle camera lenses may be used intended for scenery. Long telephoto camera lenses may be used for sports or wildlife photography. Zoom lenses that adjust their focal length among telephoto and wide-angle are really typical, and they are usually incorporated with the digital camera.

Viewfinder, Mirror and Prism

DSLR camera is special because of their pentaprism and mirror. A mirror at the rear of the lens echoes the light towards a 5-sided prism, in which its mirrored in the viewfinder. If the shutter is pushed, the mirror at the rear of the lens turns up in order to allow a straight course between the shutter and the light. The shutter opens up for the necessary period, and the light comes in towards the sensor. In DSLRs, what a digital photographer sees in the viewfinder is almost what is taken by the sensor.

Shutter and Aperture

In DSLR, the shutter is situated in between the flip-up mirror and sensor as well as the aperture is located in the camera lens. The aperture controls by contracting and expanding, the level of light passing to the lens. The shutter regulates the quantity of light dropping to the sensor through leaving it open for a certain quantity of time. The aperture and shutter operate with each other to let an accurate quantity of light to come to the sensor.


The camera sensor is actually a matrix of small units which measure the strength and colour of the light able to come to the sensor by your shutter. These units are known as sensor sites, and they are made up of a little lens, analog to digital converter and a signal amplifier. The caliber of the ultimate picture is mainly one factor of sensor quality.

In-Camera Processing

As soon as the picture has been taken with the sensor and converted to digital, fundamental picture processing is performed inside the camera. This might consist of eliminating noise and grain normal while in the sensor, modifying levels to user preference, along with other basic things that do not call for the potential of your PC. More contemporary DSLRs have more impressive computers that enable more complicated in-camera developing such as changing a picture from colored to monochrome.

Memory Card

After picture developing, the graphic is saved over a memory card for future access through computers. Flash memory is utilized since it does not need capacity to save a picture. Typical memory cards are SD, XD and Compact Flash. After a picture is on the storage device, it could be read by every computer having a proper card reader. Many DSLRs make use of Compact Flash or SD card.

The Art of Nature Photography

The term Nature Photography refers to a large genre of photography that deals with natural occurring elements and the great outdoors.

Some subjects of Nature Photography would be wildlife and animals, flowers, trees or plants, spiders, snakes and insects, landscapes, seascapes and other land formations. Photographic views can range from extreme macro photography or closeups to large panoramic triptych style photographs. Unlike documentary photography and Fine Art Photography which deal with a subject matter or artist point of view, Nature Photography usually aim to be more aesthetically pleasing. Nature Photography tries to express the beauty of its subject through color, depth and perspective.

Nature Photography is a very broad term and so contains many subcategories. Some of the more popular categories and subjects are Wildlife, Landscapes, Seascapes, Plants and many more.

Wildlife photography deals with the animal kingdom, from elephants to dung beetles, Salmon to Sharks, Penguins to Pot Bellied Pigs. Wildlife photographers try to catch their subjects in their natural habitats and normal behavior.

Landscape Photography attempts to capture the grand nature of our surrounding. The subjects of landscape photographers are usually land masses, mountains and mountain ranges, sunsets and cloud formations, waterfalls and coastal vistas. The presence of humans are usually void from landscape photos in attempt to capture the raw beauty of a scene unhampered by mans hand.

Seascape Photography looks to capture the sea and its many faces. The presence of humans or animals in seascape photography is neither required nor prohibited. There are many beautiful panoramic views of the ocean with a whale or a boat present. Seascapes also are related to the beach scene category which would include beaches, water, coastline, tropical scenes and maybe a sunset.

Plant photography deals with all forms of plant life, from flowers to vegetables, from trees to moss. Plant photography usually deals with closeups, still shots and macro photography. Flowers and extreme closeups are a popular theme of plant photography.

Nature Photography is a large category unto its self as all the many sub categories could technically be termed Nature Photography as they clearly fall under the umbrella of Nature.

Some of the most famous Nature Photographers would be Ansel Adams who pioneered Landscape Photography with his amazing black and white photos of beautiful vistas around the United States. Another would be Galen Rowell who was a photojournalist and became famous for his beautiful landscape photography. Other names would include William Henry Jackson, Eliot Porter, David Muench and Philip Hyde to name a few.

Nature is still the most popular category of photography today. Whether Nature pictures are taken professionally or by the vacationing amateur, the category of Nature Photography goes on strong and is here to stay.
