Camera Shutter Speed

  Using Shutter Priority Mode U sing the shutter priority mode on a digital camera lets you set the shutter speed and the camera adjusts the aperture to maintain correct exposure. The shutter controls the amount of time that light is allowed to enter the lens and reach the image sensor, or the film. Along with the aperture setting, the shutter speed controls exposure. The other function of the shutter speed is to control motion. You would use the shutter priority setting when motion control is an important factor in a photo. The shutter speed is the main control you have to capture motion in a photo. Anything that moves during exposure can potentially cause the final image to be blurred. If you want a moving object to be rendered very sharply in your photo, you would need to select a fast shutter speed. And if you want to show the blurring effect you’d select a slow shutter speed. Controlling Motion Controlling motion in still photography calls for a few choices to be ...

UNDERSTANDING DEPTH OF FIELD

Understanding depth of field Depth of field is the amount of the frame that is in focus, a large depth of field such as f22 will keep all or most of the frame in sharp focus, whilst a small depth of field such as f4  will focus mainly on the main subject that you are focusing on. Depth of field is also effected by the distance that the main subject of focus is from the lens. For example if shooting a subject from a mid to long distance with a large aperture of f4 will produce similar results that a small aperture would produce. Whilst shooting from a short distance will produce clearly visible differences. On this page there are six identical photographs taken at different points of focus and two different apertures. F4 = Large aperture. More light allowed through the lens. F22 = Small aperture. Less light allowed through the lens. Notice that all three photographs taken at f22 are almost identical, whereas the thr...
