image resolution-the detail an image holds

 megabyte-one million bytes

Megapixel-one million pixels

Gigabyte-one billion bytes

jpeg-a format for compressing image files

 Raw- not compressed image 

 tiff-Tag Image File Format

 png-Portable Network Graphics

white balance-the process of removing unrealistic color casts

histogram-a graphical representation of the tonal values of your image

aperture-a hole or an opening through which light travels

shutter speed-the length of time when the film or digital sensor inside the camera is exposed to light

 depth of field-the distance about the plane of focus where objects appear acceptably sharp in an image

aperture priority-a setting on some cameras that allows the user to set a specific aperture value

shutter priority-a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure

 bitmap-images are stored as a series of tiny dots called pixels

exposure-the amount of light per unit area

 watermarking-used to identify ownership of the copyright of such signal

optical zoom-This will enable you to get a closer view of the subject before taking your picture

 digital zoom-used to make the image seem more close-up

bracketing- the general technique of taking several shots of the same subject using different camera settings

 light meter-a device used to measure the amount of light

image stabilization-a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure

 noise-random variation of brightness or color information in images

 lag time-the delay between triggering the shutter and when the photograph is actually recorded

 hot shoe-a mounting point on the top of a camera to attach a flash unit and other compatible accessories

 fisheye-an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image

macro-photographing objects that are very close to the lens

telephoto-a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length

wide angle-a lens whose focal length is substantially smaller than the focal length of a normal lens for a given film plane

DSLR-A digital still image camera that uses a single lens reflex mechanism

dynamic range-The dynamic range of the subject is a measure of the range of light intensities from the shadows to the highlights

exposure compensation-a technique for adjusting the exposure indicated by a photographic exposure meter
