Abstract
Image processing is the process that turns an image from a science image to something more pleasing to the eye or highlights a structure of interest. Many image processing techniques render the image unsuitable for photometry. In this chapter, we discuss image processing techniques such as stacking, sigma clipping, drizzling, stretching, as well as the application of image processing filters. We touch on how to make colour images from black and white astronomical images using commercial packages.
