the aperture means control over depth of field. the shutter speed is the speed at which the shutter of the camera closes. the ISO is when a Lower values are great when there is plenty of light to work with. Higher ISO values are needed for working in low light.

Aperture Priority mode, your camera will vary the exposure settings depending on the aperture value you set. Having complete control over aperture means control over depth of field. The shutter priority mode works just like aperture priority, in the sense that it gives you complete control over shutter speed while making all the other settings automatically, according to the selected value.
AF mode is a autofocus mode. the AF mode won’t lock the focus and it will constantly refocus. It is a great focusing mode for sports and other fast moving subjects.
The one-shot mode will stop refocusing once it’s locked onto the subject. It will remain locked as long as you hold your finger on the shutter release, half pressed.
white balanced is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. All digital cameras have a few white balance presets. While they can do a fairly decent job, according to each lighting situation.
Depth of field is the area of acceptable sharpness in front of and behind the subject which the lens is focused. Put simply, it refers to how blurry or sharp the area is around your subject.
Drive Modes are the shooting modes in your camera, such as single shooting (where one image is taken at a time), continuous shooting, self-timer mode and more. Metering mode — often called camera metering or just metering — is something that almost all modern DSLRs and mirrorless cameras come equipped with.
exposure compensation mode is a +/- scale that will tell your camera to increase or decrease exposure, depending on your needs. It works for all semi-automatic modes (P, Av, TV) and will influence exposure in increments.
