These shots were taken using the reverse lens macro technique. I was told about this technique from a
friend on flickr and it has opened up many new doors for my photography. I have always wanted a macro lens but my wallet wouldn't let me. Reversing the lens gives the same effect but without the cost. The lens used for these shots was my 18-55mm. You can by ring mounts but these were taken just holding the lens up to the camera.
