Basic Photography Tips


            A Digital Single Lens Reflex (DSLR) camera is a digital camera combining the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and other digital cameras... 



  Basic Photography Tips:

1. Holding Your Camera:

       One of the most common problems that beginning photographers encounter when they're using a hand-held camera is "camera shake," which results in slightly blurry pictures. A good way to avoid this is to place one hand under the camera, and brace that arm's elbow against your ribs. This will give more stability. You could also kneel on one knee, with other knee forward so you can rest your camera-supporting arm on it, or lean against a wall or something for extra support.

2. Tripods:

       Without any doubt, A tripod is most important accessory. Using a tripod is a sure way to achieve a sharper image. If you want to improve the technical quality of your photographs, you have to use Tripod. The main purpose of a tripod is to avoid unsharpness caused by camera shake. Camera shake occurs when you take hand hold pictures at long shutter speeds. Every movement that occurs during the time that your shutter is open will cause  a blurred image. A tripod helps to keep the camera study.

A Photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. Believe it or not, this is determined by just three camera settings: aperture, ISO and Shutter speed. Mastering their use is an essential part of developing an intuition for photography.

3.Aperture:

     Simply we can say that, " controls the area over which light can enter your camera."

   Aperture is referred to the lens diaphragm opening inside a photographic lens. The size of the diaphragm opening in a camera lens regulates amount of light passes through onto the film inside the camera the moment when the shutter curtain in camera opens during an exposure process. The size of an aperture in a lens can either be a fixed or the most popular form in an adjustable type (like an SLR camera). Aperture size is usually calibrated in f-numbers or f-stops. i.e. those little numbers engraved on the lens barrel like f22 (f/22), 16 (f/16), f/11,f/8.0, f/5.6, f/4.0, f/2.8, f/2.0, f/1.8 etc. Each of this value represents one time the amount of light either more or less in quantity. Meaning to say, f/16 will let in 1X the amount of light than a diaphragm opening of f/22 and so forth; while on the other hand, an aperture of f/4.0 will let in 1X lesser than that of f/2.8 etc.

4. ISO:

     Controls the sensitivity of your camera's sensor to a given amount of light.
                 
5.Shutter Speed:

     Controls the duration of the exposure.
A camera's shutter determines when the camera sensor will be open or closed to incoming light from the camera lens. The shutter speed specially refers to how long this light is permitted to enter the camera. "Shutter speed" and "exposure time" refer to the same concept, where a faster shutter speed means a shorter exposure time. 

Shutter speed is a powerful tool for freezing or exaggerating the appearance of motion.

6. Depth of Field:

  Depth of field(DoF) is the distance between the objects in focus and the furthest point of focus. The distance can be increased or decreased by changing the aperture of the lens. You will often see shallow DoF used creatively in photos as it forces the focus onto a certain part of the photo.
