Go Large & Print Big

Long time friend and collaborator Grahame Knott of Deeper Dorset decided he wanted some art to hang in the house. Whatever was going to hang needed to be relevant and big enough to fill the wall in a single image. With everything in life, size matters and the opportunity to print an ortho photo was Read more about Go Large & Print Big[…]

For The Wrecks They Are A-Changin

The seabed and wrecks are dynamic environments. As divers we are not always aware of just how much things change unless something dramatic occurs. In 2012 the stern of the Karlsruhe was very ship-shape with neat lengths of teak decking in place. Then the stern winch capstan collapsed to the seabed and upended everything. Anything Read more about For The Wrecks They Are A-Changin[…]

Scapa Flow – The Results

3D Work in Scapa At least once a year we take the long drive north to Orkney and Scapa Flow for a week of diving onboard the MV Valkryie. The Flow has been used as a military base during both world wars and the German High Seas Fleet was interred and scuttled there in 1919. Read more about Scapa Flow – The Results[…]

DEMS – Another View

Slope Analysis As we have discussed before Digital Elevation Models help us understand subtle changes in depth (or height) of the subject. We also think they are art in their own right. Tucked away in the 1.4 release of Agisoft Photoscan Pro is a preference that adds slope analysis. The colours applied to the model Read more about DEMS – Another View[…]

Let There Be Light

In the Beginning… In our temperate northern waters there is a lack of light. The very thing that underwater photogrammetry needs is often in short supply and light is like a drug. You always want more. Underwater photographers get around the limits of natural light with flash guns or video lights and these generally work Read more about Let There Be Light[…]

Recent News – Maps and Mags

Sketchfab Maps The previous update discussed  how Sketchfab labs had started to test the waters with geo locating 3D models. One limitation for those of us who work with underwater photogrammetry was precise location. When generating the tagging code all we could was get close and there was no way to enter precise longitude and latitude coordinates. Read more about Recent News – Maps and Mags[…]

Gone But Not Forgotten.

Gone Late last week a tanker in Weymouth Bay managed to snag a torpedo on its anchor. Royal Navy divers from the Southern Diving Unit dealt with the problem torpedo and a link to the full story is here. The torpedo in question is almost certainly one of Grahame Knott’s Deeper Dorset finds. The torpedo Read more about Gone But Not Forgotten.[…]

Can We Take a Closer Look?

Deadlines and Detail Having masses of data is a double edged sword. Too little and your images won’t align or your models lack definition. Too much and processing time jumps exponentially. Its always a balancing act between a desire for detailed models and the time available. When The Thistlegorm Project team decided to launch the website on Read more about Can We Take a Closer Look?[…]

The Brandy Wreck – Then and Now

Background Way back 2011 Grahame Knott of Deeper Dorset found a small wreck site in Weymouth Bay. At the time the search was on to find more of the P47-D Thunderbolt but in true shipwreck hunting fashion Grahame found another mystery. Known as the Brandy Wreck, the site had four iron guns, two anchors, a millstone and ballast stones. Read more about The Brandy Wreck – Then and Now[…]
