Manipulating An Image.

The word "pixel" means a picture element. Every photograph, in digital form, is made up of pixels. They are the smallest unit of information that makes up a picture. Usually round or square, they are typically arranged in a 2-dimensional grid. 
It has three different colors in it. They are red, blue, green and it is called a bit.

In my DGM class I have been manipulating an image with Photoshop.
The image that I have chosen is a light bulb, inside the light bulb I photo shopped water, fire, and grass. Below is some evidence showing what I have done so far in Photoshop.
