Next, a quick touch-up with Image/Brightness-Contrast. Finally create a highlight and a shadow layer. This was achieved by adjusting the tonal range with Image/Levels. To create the illusion of water, I needed to displace the background where the drops were, so I

of red, green, and blue, RGB images are full-color. Each color channel has 256 possible intensity levels. More details in Color Models In a grayscale image, each point is represented by a brightness brightness value, ranging from 0 (black) to 255 (white), with intermediate values representing different levels of gray. Essentially the difference between a grayscale image and an RGB image is the number Environment page of the Preferences dialog. There are two important variables: the minimal number of undo levels, which GIMP will maintain regardless of how much memory they consume, and the maximum undo memory

The trade-off is that the less space an image takes, the more detail from the original

too much image is oversaturated Unethical Colour Levels • Brightness and contrast should be edited by adjusting colour levels – Colors > Levels Or: • Dialogue box shows histogram of colour value values aren’t hidden at the bottom of the graph Colour Levels Display Logarithmic Histogram The middle handle will adjust the midpoint of the levels and represents non-linear editing of colours.
