Technique page- wide angle, close up's

What is wide angle in photography? 
Wide angle is having a short focal length and having a field covering a wide angle.

How do you do it?
1. Firstly keep your camera zoomed out as this will allow you to get in at least 180 degrees of the for example landscape you are capturing.

2. Then you find a large space where you want to emphasis its wide angle. Then you get close to an object and angle it to make sure all the space is in the camera.

3. Lastly capture the photograph.
