Getting into Photogrammetry – debut blog from Alex Tasker
Every cloud has a silver lining. In early March our skipper called off the weekend’s diving in Loch Fyne. A shame – but I made a couple of phone calls and seized the opportunity to attend IANTD’s first, two-day Photogrammetry course instead. I’ve been experimenting with this over the last year and increasingly feeling that I needed some help!
Tim Clements, who prepared the course, was there to lead it at Vobster Quay. Although there was quite a mix of students with a variety of camera gear, everyone was able to create 3D models from their own image data that they had captured during the underwater exercises which were part of the course. There was an emphasis on teamwork, safety and dive management, as well as on the photographic tasks, and all the students got useful feedback on their in-water abilities over the weekend.
I was paired with David, an experienced technical instructor. While this was my first visit to Vobster he must have dived there hundreds of times – he’s enthusiastic about the place and I must say I found it well set up and hassle-free. We gelled easily and I really enjoyed developing the use of “angel lighting” over the three dives we did together. On dive #2 I had an issue with my primary camera and was relieved to have the Paralenz on top of my rig – I was able to extract frames from the video to produce this model: https://skfb.ly/6HYJJ (that’s the same concrete block we were playing with topside the previous day!)
Back in the classroom, Simon Brown of Deep3D provided expert knowledge on photography and image processing. I was delighted to renew my acquaintance with Simon, who’s a particularly accomplished photogrammeter (if that’s the word) and has modelled numerous interesting underwater sites. I came away with pages of notes to digest on the photography itself and subsequent workflow.
We were also treated to some great 3D VR demos from Marcus Blatchford, illustrating some of the potential for our 3D models. He lent some much-needed computing power too, putting together this model from the image data I captured on dive #3: https://skfb.ly/6HTHX
We all deemed the course a real success; I’m certainly hoping to share some far more interesting models in the near future…
After a two-year tour of UK art galleries, community spaces and aquariums, the Shark Trust’s acclaimed Oceanic31 exhibition takes its final bow at the Royal Geographical Society later this month. And the unique collection of artwork, depicting 31 species of oceanic sharks and rays, donated by 31 artists, is now open for bids from art lovers and shark enthusiasts. The online auction, launched today, will close on the 7th December at 8pm (BST). The money raised will support the Shark Trust Oceanics Programme.
People can now bid on 27 of the artworks by visiting this website:

It is a chance to own a beautiful piece of original art and to support the Shark Trust. The timing of the auction also means that these would make a very special Christmas gift for any shark-lover.

Whichever you choose, you will be supporting the work to protect these amazing animals.
One of the pieces of art has been selected to be auctioned live by Steve Backshall at the For the Love of Sharks event at the Royal Geographical Society in London on the 29th November. In addition to this, two further pieces will be raffled at this event, giving people a chance to win an incredible piece of shark art. For the Love of Sharks is the Shark Trust’s flagship evening. A night to celebrate sharks. Steve Backshall is the headline speaker at this event that will see other prominent shark advocates join him on stage.
