Look it in Perspective!

This is a step by step video, where it shows how 2 vanishing point perspective works, it is very important to consider the line as the beginning, its relationship with the horizon line and the 2 vanishing points in the corners. Projection, there is another key for the composition, two points of the main line are shot to the VPs, after that we have a long plane at each side of the line. We have to work with the concept of the square and its angles, there is a 45º diagonal that cuts a regular square, so it is used to calculate the depth of the plane in perspective. Using the projection lines as guides we can conform the next planes, just as show in the video we use 5 different projected squares to make our final composition in Adobe Photoshop.
