Images can be changed by using the graphical programs such as Paint Shop Pro, Adobe Photoshop etc. For the creation of this example Adobe Photoshop was used. In a long line of options such programs offer, the most often used are Sharpen (to sharpen the image) and Brightness/Contrast. Depending on the desired effect, you can also use a wide range of filter options, such as Artistic, Blur, Brush, Distort, Noise, as well as drawing tools. Each image size is adjusted by using the function Resize and Image size.
