Saturation
Resolution
Pixels
Hue
Grain
Contrast
Highlights
Shadows
Mid-tones
Contrast adjusts the relationship between the light and dark areas
of the image. Increasing the contrast will make the highlights
brighter and the shadows darker. Increasing the contrast can also
increase the apparent sharpness of the image.
Film uses tiny silver-halide crystals to record light. When developed,
these crystals create a subtle texture to the image known as grain.
The degree of grain depends on the film, image density, and image
detail.
Highlights refer to the bright tones in the image. If the highlights are
too bright, image detail is lost. If the highlights are too dark, the
image looks flat and dull.
Mid-tones are the range of tones between the highlights and
shadows.
Pixel derives from the words picture element. A pixel is the smallest
point used to create an image.
Resolution indicates the number of pixels used in an image. Print
resolutions are usually given in dpi (dots per inch). Monitor
resolution indicates the maximum horizontal and vertical
dimensions in pixels of the display.
Saturation refers to how vivid the colors of an image are.
A hue is a specific color.
Shadows refer to the dark tones in the image. If the shadows are too
light, the dark areas look smokey and flat. If the shadows are too
dark, image details are lost.
