Photoshop Photo manipulation bulb water - What is a Pixel

Water wave in light-bulb

I used images off Google Images 

I manipulated a water wave into a light bulb on Photoshop
I decided to manipulate more that one image and try different things like the light bulb and the water

For Photoshop we first had to watch videos about pixels
If you grab a magnifying glass and put it up to a digital screen you can see tiny little squares, The little squares are called pixels. In the pixels there are even more little squares. The Pixels are made out of three colors Red, Blue and Green and they are called RBG's

The more pixels you have the clearer/denser  the image, every single pixel can have approximately 16 and a half million colors

Anti-alias allow images to look smoother for example you cannot make a circle out of square pixels so you can use a tool called Anti-alias allows you to smooth the edges by, adding different shades to the circle
