Anti-Reflective

Not a very original subject I know but it's interesting non the less. The D90 has a set of inbuilt filters which when using Photoshop for post processing you certainly don't need. However it has one quite original feature, the ability to produce a pseudo fisheye image whilst leaving the original image untouched. This is one such, where it accentuated the reflections colours and shapes, over and above the norm...making a quite pretty pattern, larger in the frame than otherwise.
