WINE Cloning Away Unwanted Parts The bottle was made from a photo of a decanter filled with dark red wine. This was a bit trouble- some because I wanted the bottle to be empty, or at least filled with Making Things Glow The glow layer was made by filling a feathered horse and rider selection with red, yellow and white, each time with lower feather values, and setting the layer to Screen Mode.

possible modes: RGB, grayscale, and indexed. RGB stands for Red-Green-Blue, and indicates that each point in the image is represented by a "red" level, a "green" level, and a "blue" level. Because every every humanly distinguishable color can be represented as a combination of red, green, and blue, RGB images are full-color. Each color channel has 256 possible intensity levels. More details in Color Models image has three. An RGB image can be thought of as three superimposed grayscale images, one colored red, one green, and one blue. Actually, both RGB and grayscale images have one additional color channel

on the type of channel, e.g. in the RGB color model the value in the R-channel means the amount of red which is added to the colour of the different pixels, in the selection channel the value denotes how you are interested. Each pixel or point when in this mode consists of three different components. R->Red, G->Green, B->Blue. Each of these in turn can have an intensity value of 0-255. So, at every pixel CHOOSE A TOOL Figure 3.34: Paint tools in the toolbox Then click on the paintbrush. Any of the red-highlighted tools on the above toolbox can do lines. 4.

most common combination is red, green and blue, which are the three additive primary colours. This is known as the RGB Colour Space. In an image editing software, red, green and blue are referred stands for saturation and V stands for value. Hue ranges from 0 to 360 (degrees). 0° stands for red, 120° stands for green and 240° stands for blue. High saturation means that the pixel is coloured

GIMP GIMP Basics - 1 Cropping an image The cropping tool is located in the toolbox (circled in red). Select it and draw a box around the area you want to keep.
