Creating an Understanding the Elements of Exposure poster...
Create a poster that illustrates the major concepts of photography. Equivalent exposure, aperture, f-stop, Depth of field, and resolution should all be explained both in simple terms, and in photographs containing examples of them (photographs, drawings, graphs, etc.). The goal of this portion of the exam is to equip your website with a page that explains the concepts that you have learned in this class to the viewers of your site. It should be presented as if the viewer has no prior experience with photography (think Photography for Dummies!). In order for you to do this successfully, you must have a working understanding of the concepts yourself…so prepare yourself by reading, asking questions in class, and studying the various websites which explain these concepts in detail.
Many of the websites that attempt to explain exposure tend to be very "wordy". Since photography itself is visual by nature, I've always felt a better connection when "learning by looking". Therefore, the poster should be rich with images, graphs, illustrations, etc., while keeping the verbage simple and succinct.
Getting Started: Create a Photoshop document that is 13 inches wide by 19 inches in height at a resolution of 150. The rest is up to you!
Below are some examples of illustrations found on various websites dealing with the basic concepts of photography. ALL PHOTOGRAPHS USED IN YOUR EXAM POSTER MUST BE YOURS!!! You may take photographs for the poster, or utilize images that you've previously taken provided they accurately depict one or more concepts. Illustrations, graphs, etc., such as the ones below, must also be created by you using Photoshop, Illustrator, or a similar image creating software.
Good Luck!

Terminology
The Language:
Pixel: The smallest unit of a digital image that can be represented or controlled.
Megapixel: One million pixels gridded into a pattern in the shape of a rectangle.
Resolution: The number of pixels that make up an image. An image that is 2048 pixels in width and
1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could
refer to it as 2048 by 1536 or a 3.1-megapixel image.
Image Size: Image size is a direct product of resolution, but may be "scaled" visually by resorting resolution.
For instance, a 5x7 inch image at a resolution of 300/inch would appear as 10x14 inches when the resolution is lowered
to 150/inch. The amount of pixels doesn't change, but the number of pixels per inch can change (the size of each pixel)
without changing the image size.
The Theory:
Aperture: Diaphramatic opening in lens that increases or decreases in size to control
amount of light that passes through. They are measured in fStops: f2.8, f4, f5.6, f8, f11, f16, f22.
Shutter: Curtain that opens for a specified amount of time, or “shutter speed” to
control the amount of light that passes through. These are measured in fractions of seconds.
Exposure: A combination of an aperture and a shutter speed that results in a specific
amount of light entering the camera.
Overexposure: Too much light entering the camera.
Underexposure: Too little light entering the camera.
Equivalent Exposure: Two combinations of aperture and shutter speed that allow an
equal amount of light into the camera. For instance, f8@1/30 equals f5.6@1/60...different
numbers, same amount of light.
Depth of Field: The distance between the nearest and farthest objects in a scene that appear sharp.
Pixel: The smallest unit of a digital image that can be represented or controlled.
Megapixel: One million pixels gridded into a pattern in the shape of a rectangle.
