I really like this leviation photo it looks very sereal as well as naturalistic. The shadow under the subject defines it as being a floating photograph as you can clearly see that the girl is above the ground. When creating levitation photos its always important to identify where the light source/source's are coming from so you can create the drop shadow and put it in the correct position. You can see in this photo that the main light source is coming directly above the subejct as there is a circle of light on the floor, this means the shaodw must be underneath the subejct for it to look realistic. Some photographers incorporate intense detailed background which could potentially distract you from the floating subject. One of the reasons i like this photo is that is uses a very simple background which adds to the effect this picture has. This photo has a lot of leading lines in both the girl and the background. The angle that the photo was taken excentcuates the shape of the corridor, the foregorund is much wider than the background which draws your eyes towards the subject which is positioned slightly to left. The subjects hair is the thing that shows the audience the type of leviation effect being achieved. The fact that her hair looks as if its being blown by a strong wind could sugegst that she is falling as apposed to levitating. This can be achieved by wafting a large piece of card to give the wind illusion.

I really do like this photo and i plan to replicate this effect in a similar manner. I think the easiest way to replicate this effect is to take two photos, one with the model perched on a stool (in a similar pose), and the second with just the background. I will then run it through photoshop and delete the stool. This is the main way i achieve my levitation effect as it relativley simple and effective method
