Document Summary
Field of view as it relates to focal length. Shorter focal length = wider field of view. Longer focal length = narrower field of view. 40-50mm - long perspective, 100mm - narrow field of view. Aperture/f-stop - determined by aperture opening and amount of lighting allowed in. Shutter speed - length of time shutter is open and light is allowed in. Iso - the film speed and camera sensor sensitivity. Every time you take a photo, the lens of your camera opens to let light in. Aperture setting determines how much or how little lights falls into your camera. How adjusting your plane of focus can drastically change your photos. When your lens is wide open, the background is typically out of focus. When your lens is only open a small amount, everything from the foreground to the background is in focus. Wide open = background is out of focus (ex. f/1. 8, f2. 8), a lot of light.
