Ref: Anonymous@181200.... the sun is obviously behind whoever took the picture, pointing toward the thing in the sky. you would not be able to see the rainbow as this is also a reflection of light. the shadow on the wall is away from the line...the sun is appears to be from behind the left shoulder of the person who took this picture, the shadow looks pretty authentic and correctly orientated. anyways...besides all that its easy to detect if a photograph has been altered....very easy.
