Photoshop and many other image-editing software have preset filters that allow you to quickly and easily take an image and alter it in a way that makes it more visually appealing or artistic.  Here is an example of a photo I took of a house:

Then, in the second image, you can see what it looks like after I spent less than 5 minutes in Photoshop, applying a filter, adjusting the saturation of the color, adjusting the contrast, and then cropping it to the size I wanted, to make the composition of the image more interesting.

It’s easy and fun – try it some time…
