Camera Exposure
Shutter Speed
The time it takes for the camera to open and close its shutter. This can range from 30 seconds to 1/4000 of a second. Faster shutter speeds (1/4000) freeze the frame and capture only the light that is present in that small amount of time. Slower shutter speeds (30 seconds) capture all of the light that is let into the frame. They can capture motion as well.
Slow
Fast
Aperture
The hole or an opening in a camera that light travels through. More specifically, the aperture is the opening that determines the angle of light rays that come to a focus in the frame. Aperture is recorded with an f-number. The lower the number, the larger the diameter of the aperture opening. When the number is higher, that means the aperture itself is larger, and more things are in focus. With lower aperture, the focus of the photo is usually only on one specific subject.
Low
High
ISO
How sensitive the camera is to the available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. When the ISO number is increased, the noise or graininess of the picture goes up. Usually higher ISOs are used when taking a photo in the dark without flash, or to balance out the aperture and shutter speed. Lower ISOs are used when there is plenty of natural lighting already available.
Lower (Still not very low)
Higher (Still not too high)
