|RESOLUTION, BRIGHTNESS, CONTRAST
METEOROLOGIST JEFF HABY
RESOLUTION: Higher resolution is more crisp. Pictures and images look more clear and
crisp when resolution is high. The smaller the pixel size, the higher the resolution. Visible
imagery has a higher resolution than Infrared imagery. Example below:
BRIGHTNESS: If a picture or image looks too white then it was too much brightness. If it is
too dark it does not have enough. On satellite images, the whiter the object the brighter it is and
the darker it is the less bright. In the image below the clouds are brighter than the land and the
thicker clouds are brighter than thinner clouds.
CONTRAST: If it is difficult to tell features apart and gradients of color merge instead of
having a sharp boundary then the contrast is low. Increasing contrast makes it easier to
pick out features and boundaries of objects. The images below are altered to show a low
contrast and a high contrast.
