Lighting

One can define photography as "the recording of light rays". That's why taking a good picture depends so much on choosing the lighting carefully. I found this definition on http://photo.net/making-photographs/light , also on this website there is loads of useful information about the different lighting techniques and types.

http://www.picturecorrect.com/tips/use-of-light-in-photography/ , this website talks more about how the angle should be taken into consideration to create a specific effect

This photo was taken by Vee Spears. The colourful light is mostly at the background and it highlights the smoke and the plants in the background. I think that the photographer used artificial light at the front to make the person stand out and to be the focus of the photo, also he is very  pale and artificial light can make you look very pale when it's right in front of you also there is shadow on his outline which suggests that there is light at the front and his ribs do not have any shadowing on them which means that there is light shining right on them.
