The size of the opening in the lens also known as f/stop. (a smaller aperture has a bigger f/stop number--lets in less light) The numbers represent ratios of the lens focal length to opening. The lens focal length is how long the lens is in millimeters. So f/2 is a wider open aperture than f/16 because the numbers are fractions.
 * Aperture:**

viewing distance can influence our perception of it. Depth of field allows the photographer to either focus in on something close or maybe something that is far away. Either way it shows distance.
 * Depth of field:** Depth of field is the range of distance within the subject that is acceptably sharp. The depth of field varies depending on camera type, aperture and focusing distance, although print size and


 * Shutter Speed:** Shutter speed is how fast the shutter opens and closes to capture the light. The bigger the the number the faster the shutter speed.

Histogram: Tool that shows a quick summary of the range of tone that is in the image. When the graph is high that means the the more pixels of the tone of the image are there.
 * Noise:** Problem in digital cameras. Most commonly appears as either random colored dots sprinkled around the image or uneven colorization of what should be smoothly colored areas. Noise can ruin photos.

while taking the picture.
 * Burst Mode:** One can take many shots in this mode in under a minute in a constant series. This is useful to show many actions and movements such as children and sports. To do this hold down the shutter


 * White Balance**: Many cameras manually have this feature. With white balance the setting reads the colors and looks for the perfect white balance. Without white balance many photos turn out with too much of one color, such as yellows, blues, or reds.Self timer: One uses a self timer normally when they wish to also we in the photo. Useful for portrait photos. Typically in menu for a range from 2-10 seconds.


 * Pixels:** The smallest discrete component of an image or a picture. (Color dot, greater number of pixels is better resolution). More resolution means a clearer photo.

focus in and out to choose exactly what they want as the main subject.
 * Auto Focus vs Manual Focus**: Auto focus is where the camera adjust on it’s own. The camera picks the subject and decides what is in focus. While manual is where the photographer adjusts the lens to

higher the ISO number the less light needed, however a lower ISO setting on one’s camera usually means less noise in the photo.
 * ISO (international standardization organization)**: A number rating that indicates a digital camera’s sensors sensitivity to light. The

File Format: Define each and explain how they differ from each other. .tiff – Great for printing images. This format has no quality loss due to compression. It is the standard for graphic and imaging software and publishing.

.jpeg – Most popular digital camera image file format. Provides a small file size that is great for the smaller prints. It is important to know that this file format compresses images, which can create some loss in image quality.

.raw – File contains unattached “raw” data from the image sensor of a digital camera. Used mostly by professional photographers, this format gives them greater control over image enhancement. To see example images
