The shallow reef flats in 1 or 2 meters are a great place to start Blue waters swirl above and a hint of clouds in a blue sky prevail. Early morning shafts of sunlight bathe a coral head with light producing a surreal image of corals in the sunlight. eteran pioneer Australian Underwater Photographer the idyllic location and accommodation, the wonderful hospitality, Kevin Deacon decided to forgo all other genres of the range of dive sites, dive boat facilities and all round diver support, one will not suffer for their art here! clown fish and fast growing Acropora & soft corals. produced a portfolio that I believe is faithful to the genre of Vunderwater photography during his most recent tour While cruising this area the creative mind must be fully engaged "Beautiful Reefs".

Underwater Survey for Oil and Gas Industry: a Review of Close Range Optical Methods
remote sensing Review Underwater Survey for Oil and Gas Industry: A Review of Close Range Optical Methods Bertrand Chemisky 1,*, Fabio Menna 2 , Erica Nocerino 1 and Pierre Drap 1 1 LIS UMR 7020, Aix-Marseille Université, CNRS, Université De Toulon, 13397 Marseille, France; [email protected] (E.N.); [email protected] (P.D.) 2 3D Optical Metrology (3DOM) Unit, Bruno Kessler Foundation (FBK), Via Sommarive 18, 38123 Trento, Italy; [email protected] * Correspondence: [email protected] Abstract: In both the industrial and scientific fields, the need for very high-resolution cartographic data is constantly increasing. With the aging of offshore subsea assets, it is very important to plan and maintain the longevity of structures, equipment, and systems. Inspection, maintenance, and repair (IMR) of subsea structures are key components of an overall integrity management system that aims to reduce the risk of failure and extend the life of installations. The acquisition of very detailed data during the inspection phase is a technological challenge, especially since offshore installations are sometimes deployed in extreme conditions (e.g., depth, hydrodynamics, visibility). After a review of high resolution mapping techniques for underwater environment, this article will focus on optical sensors that can satisfy the requirements of the offshore industry by assessing their relevance and degree of maturity. These requirements concern the resolution and accuracy but also cost, ease of implementation, and qualification. With the evolution of embedded computing resources, in-vehicle optical survey solutions are becoming increasingly important in the landscape of large-scale mapping solutions and more and more off-the-shelf systems are now available. -

Chapter 6 Underwater Photography
Chapter 6 Underwater Photography It is hard to imagine a more difficult endeavor than taking pictures underwater. You have to be at least partially crazy to get involved in it, and if you are not crazy when you start, it is virtually guaranteed to make you crazy. First, you have to learn to survive in an alien environment. Before you even think about the highly specialized photographic equipment required, you have to learn how to safely breathe and move about underwater. That means you have to become a certified diver. The most important qualification required to become a good underwater photographer is to be a good diver. You can’t worry about things like f- stops, depth of field, shutter speeds, exposure, point of focus, and other technical photographic stuff if you are not comfortable underwater. Things like breath and buoyancy control, awareness of time, depth and tank air pressure, must become second nature, like shifting while driving a car with a manual transmission. Underwater photography, even with excellent diving skills, state-of-the-art equipment, and plentiful subjects, is still a very low batting average endeavor. You fail much more often than you succeed. That means that you discard a lot more images than you keep. But the occasional “keeper” can make up for all the throwaways. Underwater photography offers the highest highs, and the lowest lows of any endeavor I know. Everything in underwater photography is stacked against success. First, unlike taking pictures topside, you have a very limited amount of time to capture your image (before you have to surface or drown.) Whatever underwater subject you are seeking on each dive, you have to find it in less than an hour, you can’t hang around all day waiting for something to appear. -
