Pay attention to exposure element for better photography
Exposure is one of the most basic element in photography, which can be mastered with practice by paying attention to camera adjustments of shutter speed, aperture, and ISO mode. If one wants to take good photographs, he/she must learn how to control the exposure of a picture. Before clicking the camera, take a minute or so and adjust your exposure setting to make it your habit for better pictures.
Exposure is the total amount of light, which is captured by the camera during the process of taking a photograph. Digital cameras have three main elements to control the amount of light entering the camera - shutter speed, aperture, and ISO.

Shutter speed is related to the time for which the aperture is open.  The longer the shutter is open, the brighter the image. Quick shutter speeds can have the negative effect of a darker image, since the camera has less time to capture the light.

In photography, shutter speed is measured in fractions of a second. A shutter speed for shooting a party in a dim restaurant might be 1/60th of a second, while an image at the beach on a bright day might be as fast as 1/4000th of a second.

Further, in a camera, the aperture is a circular hole through which the light passes to the sensor. A smaller hole allows less light but more depth of field. It basically controls the amount of the picture that is in focus. Aperture is generally expressed in f-stops on a camera.

If you want a portrait with a nice creamy background, a low f-stop, such as 3.5 is used, whereas if you want to take a landscape image with everything in focus, then you?ll want an f-stop like 11 or 22. The low f-stop of 3.5 allows lots of light, whereas a high f-stop like 11 or 22 would not allow much light to get to the sensor and produces a darker image. In essence, low aperture allows lots of light and short depth of field; a high aperture allows little light and makes the entire image in focus.
