Things I've Learned About Photography - Essay Example

When looking at a scene, everything in it may seem more or less sharp, though sometimes in the final shot only a part of the image appears notably sharp. The zone of sharpness is referred to as the depth-of-field. The smaller the size of the aperture, the wider the depth-of-field. Very small apertures may require using a tripod to reduce the camera shake resulting from long shutter speeds. However, if the concentration is on one part, a large aperture should be selected depending on the maximum aperture of the camera lens in use.

For general shooting medium aperture is appropriate. Shutter speed refers to the measurement of that time when the shutter is open. The measurement is in seconds and sometimes fractions of a second. If the speed of the shutter is faster, the time taken by the image sensor to be exposed to light is shorter. If the speed is slower, the time taken by the image sensor to get exposed to light is longer. Photographing subject that are in motion, results in different image effects at various shutter speeds.

Fast shutter speeds may “freeze” motion .Slow shutter speeds cause blur. The blurry effect is due to: camera movement and subject movement. This means that it is easier to photograph the subject without causing a blur or a “freeze” motion with fast shutter speeds. Contrast to this, slower shutter speeds are matched to suggesting the motion, like that of moving subjects or flowing water. Changes in the shutter speed give the photographer control over motion. The shutter speed regulates light and motion.

Shutter speeds that are slow let in more light creating a lighter and blurry image. Faster shutter speeds let in less light creating a darker and sharper image. To adjust the shutter speeds, one needs to switch the camera either to shutter priority or to the manual mode. ISO sensitivity refers to the measure of a camera’s capability to capture light. The
