Exposure
February 16, 2014
My last post tells us about the ISO settings available in the digital cameras and how to play with them.Lets advance now to the next level. The Exposure, is a blend of three things Aperture, Shutter Speed and ISO.When these three things are mixed in right proportion 'the best' is the OUTCOME.
This post will now give you a brief idea about Aperture, Shutter Speed and Exposure. Lets start with Aperture.
Aperture -
Aperture is how big or small the opening in your lens is. It is also referred to as the F-stop. In general, the larger the F-stop number, less light the lens lets in. On the other hand smaller the F-stop, more the light lens lets in. It also affects the 'depth of field'. DOF refers to how much of your scene is in focus. Lower the F-stop smaller the depth of field and more the F-stop larger the depth of field that is more of the image in focus.
Shutter Speed -
Shutter Speed is how long the shutter opens to allow the sensor to be exposed to light. Longer the shutter speed indicates more light is allowed to reach the sensor. But keep in mind this causes the motion blur. So using tripod is advisable while capturing at slow shutter speeds. Higher shutter speeds allows you to capture objects in motion.
A good exposure happens when these three things are blended together in such a way that the image isn't too dark or overexposed (too light).
So go out and take your chances. Adjust the settings and capture those beautiful moments.
