HMS Colossus sank in 1798, the wreck has five of her 18 pound cannons still sitting in their gunports - muzzles buried in the sand. The underwater photographs were taken in 2021 by CISMAS photographer Sharon Austin. We spent months trying to process these in Metashape, but odd distortions and holes were evident (due to large amounts of mobile weed in the water). [Tom Goskar](https://sketchfab.com/tomgoskar/) processed the model in Nomad Sculpt - and filled in the holes.
