Color Correction
Pixels: Smallest element of an image that can be individually processed in a video display system
Image Resolution: Refers to the number of pixels in an image. Can also be identified by the width and height of the image as well the total of pixels.
Megabyte: 10 to the 6th power but is the amount of storage a camera can hold in a disk.
Megapixel: One million pixels.
Gigabyte: The speed at which the human eye processes to the brain. Or it can be a measure of storage capacity equal to 1024.:
Jpeg: A file format for digital photos and other digital graphics
Raw: An image file that contains minimally processed data from the image sensor of either a digital camera, image scanner, or motion picture film scanner
Tiff: Store image data in lossless format makes a Tiff file archive. Can be edited and resaved without losing the image quality.
Png: File format for image compression that is expected to replace GIF
White Balance: Removing unrealistic color casts so that the object will appear white in person are rendered in the photo.
Histogram: A graph that represents the tone of your image.
Aperture: Unit measurement that defines the size of the opening in the lens that can be adjusted to the amount of light reaching the film or digital sensor.
Shutter Speed: Length of time when the film or digital sensor inside of the camera is exposed to light.
Depth of Field: The distance between the nearest and furthest object in a scene that appear sharp in the image
Aperture priority: Camera mode dial and allows you to change the value of the number
Shutter Priority: A system that is selected by the person and the appropriate aperture is set by the camera.
Bitmap: Images that is stored as a series of tiny dots called pixels. When you zoom in the bitmap image, you can see individual pixels that make up the photo.
Exposure: The amount of light per unit area reaching a photographic film
Watermarking: To identify its ownership of copyright to the photo or image.
Optical Zoom: Lets you zoom in or out in the subject on the LCD or viewfinder. Lets you get a closer view on the subject before taking the picture.
Digital Zoom: To make the image seem close up. Can be the same as cropping and enlarging a photo.
Bracketing: A technique of taking several shots of the same subject using different settings.
Light Meter: Can be digital or analog electronic circuit that determine the shutter speed and f-number that is selected for an optimum exposure to give a certain lighting and film speed.
Image Stabilization: Reduce blurring associated with the motion of the camera or other photo taking device during exposure
Noise: Random variation of brightness or color information in images and can be aspect as an electronic noise.
Lag Time: Between stuttering and when the photograph is recorded. This happens when there is a fast-moving object/person in motion.
Hot Shoe: A socket on a camera with direct electrical contacts for an attached flashgun, etc.
Fisheye: Ultra-wide angle lens that produces a strong distortion to create a wide or hemispherical image.
Marco: Photographing objects that are very close to the lens to the film or sensor.
Telephoto: Long-focus lens in which the physical length is shorter than the focal-lens
Wide Angle: Refers to the lens whose focal is substantially smaller than the focal length of a normal lens.
DSLR: Combines the optics the mechanisms of a single-lens with a digital imaging sensor.
Dynamic Range: Difference between the lightest light and the darkest dark. The highlight can be wash out white or darks become black blobs when the subject exceeds the camera’s dynamic range.
Digital Negative: Long-term storage that is generated in multiple proprietary formats.
Exposure Compensation: Way to force your camera to make your photo brighter or darker to the degree you tell your camera to go to.
