These additions to the Pond Project have, despite appearances, received little modification after taking. The effect is all down to a modified lens - one of it glass elements is flipped around - its a cheap 50mm Zenitar. 

The modifications make it rather impossible to gain accurate focusing; especially following the loss of my tripod to the waters of the Thames last week. I rather like the effect, having used it on a selection of Instagram shots (1, 2, 3), and was keen to experiment with it out in the field.
