What is Shutter Speed? In very simple terms, shutter speed is the time it takes for the shutter on the camera to open and close. When the shutter is open, light is let in to the sensor and when it is closed, no light gets in.
We use filters in photography to bring back an image to the way our eyes have perceived the original scene. Some times it's not possible for our cameras to record an exact scene - so we have to rely on the manufacturers of camera products.
The aperture has another important feature besides just controlling the exposure. It also controls how far the depth of field is, or how a long distance it will still be focused. Most cameras have the ability for the photographer to manually set the focus, but this is another thing.
Candid photography is photography that focuses on spontaneity rather than technique. Your subject's focus is not on the camera, but on their current task.
Modern cameras are highly automatic in operation. They have auto focus and auto exposure. The camera will focus on the subject - often identified by a small circle or square at the centre of the viewfinder - and calculate an appropriate exposure by detecting the level of reflected light - usually from the same spot.
