Exposure Terminology
Scope
Photography is a technological field of endeavor, and without that background, the photographer is limited to either being controlled by their camera or at the mercy of luck. Right now, you are stuck TAKING pictures. You need to move towards MAKING pictures. Do you understand the difference?
This is all written work. Your answers should be easy and clear, such that ANYONE, especially you, can understand them. You need to have this stuff firmly in your head. This is due as a blog post no later than Wednesday, 10/3 at midnight. Be prepared for an oral examination with me on Thursday, 10/4.
If you have problems getting to information that seems relevant, add the word "Camera" to your search phrase.
ISO Speed - The sensitivity to light
Aperture - A space where light passes into a camera.
Shutter Speed - Exposure time, the effective length of time a camera's shutter is open.
Using only ONE SENTENCE, explain:
What is an exposure meter (a light meter)? Photographic equipment that measures the intensity of light.
How does it work? The light intensity in a given area that corrects settings for an optimum exposure.
What is an incident-light meter? An exposure meter that measures the light falling on the scene.
What is a reflected-light meter? A meter that reads light reflected from the scene/subject.
What is a Center Weighted Meter? A exposure that goes through the lens that measures light values from the entire scene.
What is an Evaluative/Multi-Segment Meter? It is a setting on the camera, it is more used for portraits and even backlit subjects.
What is a Spot Meter? Spot meter is useful for subjects in high contrast.
What sort of exposure meter is on your camera? I don't know what mine is.
What is overexposure? Overexposuring is exposing too much light into the camera.
What is under exposure? Under exposure is not having enough light brought into the camera.
What is depth of field? The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
Write as much as you need to, to explain:
What is the relationship between aperture, shutter speed, and ISO? ISO is the sensitivity to how much light gets into the picture. Aperture is the size of the opining in the lens when a picture is taken, and shutter speed is the amount of time that the shutter is open.
What is exposure compensation? Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter.
