ABSTRACT
Science pictures are more than simply pictures, they are visual representations of scientific data. Science pictures contain visual information about an object or event that may need to be evaluated at another time. Digital image processing software allows scientists to adjust data in ways that was never possible with film, and the capabilities continue to improve. Image processing software accomplishes two tasks. It allows pixels to be selected and it allows for the modification of the selected pixels. Each of these tasks is separate and fundamental to using an image-editing program. The General Image Manipulation Program (GIMP) is an open source bitmap and raster image editor launched in 1995 by Spencer Kimball and Peter Mattis. It allows for easy pixel selection methods and pixel retouching including drawing, re-sizing, cropping and many other important tasks. Digital color is described by an imaging processing program using mode. The most common modes are RGB, CMYK, grayscale, Index color, and LAB color.
