Twisted Wreckage

You can see the ghost images of fish resulting from blending 5 RAW images (since they are moving). The diver is added later. This is not a great image, but it's fun. At 900 pixels or a passing Instagram glance it looks cool, but it would be much stronger if the ghost fish images were cleaned up, and the diver brought into the frame with purpose.
