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.   |
