Two days ago I got a rather lengthy ego flattering email from IUCN via Flickr, requesting permission to use my finned shark photos in a publication about endangered marine animals, meant to raise awareness about conservation issues and inspire people to action.

These sad pictures actually already got some broader public attention before, thanks to volunteers and web reporters, but this time they'll be exposed to an even larger audience:

... We have decided to produce a book targeted to the public to raise awareness about the latest issues facing ocean animals. Our aim is to inspire people to action through a collection of witty but true stories and inspiring photos of marine creatures. The book is called: "Adrift, Tales of Ocean Fragility". ...

netted turtle
... The book features twelve stories of different ocean animals such as lobsters, sharks, tropical corals, abalone, wrasse, eider ducks, tuna and more, each illustrated with stunning photos. ...

finned sharks
... The book will be launched at IUCN’s World Conservation Congress this October - this huge conference takes place every 4 years and is the largest regular gathering of conservation organizations - we are expecting 8,000 people this year. The press will be invited to the formal launch of the book. The book will be sold at aquariums throughout the world and online through various re-sellers. ... The book has no commercial intent whatsoever. All proceeds from the book will go to conservation projects focused on marine species. ...

With phrasing like: You will be prominently credited on the photo credits page of the book ... to help give your photos more profile. and This is a great opportunity for you to help the cause of marine conservation, and to achieve a small slice of fame for your photography!, how could I possibly have said no :o)

TillyTec LED 1000 underwater light

Having a movie project in mind needing illumination, I once more turned to TillyTec, maker of lights for divers venturing into darkness. And came back home with a bright new TillyTec LED 1000.

Modularity & expandability.

Power: 100W halogen equivalent output according to the manufacturer's specifications (5000°K, 25000 Lux).

Burn time: 195' on my Green Force Flexi II NiMh battery.


It is not possible to dim the light's output, nor change the beam's angle from e.g. spot to flood. Remark that while you can slightly adjust the beam's focus while underwater, it's not really recommended to do so, due to the risk of flooding should any dirt have lodged itself on the lens's o-ring.

The clear glass lens can be replaced by a frosted one for more diffused lighting purposes.

A Goodman handle is available as optional accessory, and highly recommended for e.g. cave or wreck diving, where having one's hands free for other tasks may be crucial.

Great light both for recreational & technical diving.
