There are a few terms you should become familiar with when you're starting out in the world of photography. Aperture: A camera's aperture lets light in and its size is recorded with f-stops or f-numbers. Shutter speed: Shutter speed determines how long a camera's sensor is exposed to light (exposure time). Generally, you want higher shutter speeds for motion and action photography. ISO: ISOs can be set to change how sensitive your camera is to light. A higher ISO is for higher sensitivity, and a low ISO setting reduces sensitivity. Exposure: Exposure is how much light reaches a camera sensor.Bokeh: Bokeh is the blurry background effect you often see in professional photos. This can be achieved with lenses or during the editing process. Depth of field: Depth of field is the distance between the closest and furthest objects that are still sharp. You can change this by tweaking your aperture settings or by switching lenses. Burst: Burst modes are used to simultaneously capture images in quick succession. You could use this mode to capture a bride walking down the aisle, for example, but there may be a subsequent delay in shooting as they are processed. RAW: RAW is a file format -- like JPG or PNG -- which photographers often prefer. Images are not compressed and so these source images save a lot of information. During editing, the more information, the better. Noise: Noise is the term used to describe distortion in images that can appear as specks or grain.
