Lighting Positioning

On the right is showing the lighting source from the left which gives the half eaten side of the apple a dark mouldy looking effect while keeping the clean uneaten part of the apple light and shiny.

To the left has the lighting coming from the right, which is lightening the eaten part of the apple giving it not so much of a mouldy effect. It now just looks half eaten not rotting.

 To the right this apple has been lit from both sides giving it two shadows and an even spread of light on the whole apple which doesn't highlight any areas of the apple.

These pictures show how the placing of the lighting can affect the way in which the picture is perceived.
