Equipment
For those of you interested in kit, here are details of camera equipment that has been used for most of the images that appear on this site.
Camera system currently used:
Nikon D90 SLR camera in a Sea & Sea DX-D80 underwater housing.

.
Lenses used:
Nikkor 60mm f2.8 micro
Tokina 35mm f2.8 macro
Nikkor 10.5mm f2.8 fisheye
Tokina 10-17mm f3.5-4.5 fisheye zoom

.
A housed SLR camera is used despite its bulk and complexity as certain images would be difficult to take without it. Lens choice is restricted to two short macro lenses and two very wide angle close focussing lenses. A standard flat port is used for macro lenses and either a compact dome port or a fisheye dome port for wide angle lenses.
Sea & Sea do not make an underwater housing for the Nikon D90, so a previously used Nikon D80 housing has been modified in order to use a D90. Customisation has involved drilling new holes in the rear of the housing and adding four new control buttons. An Inon 45 degree viewfinder has also been fitted to replace the standard viewfinder.

.
Other kit used:
Sea and Sea YS110 strobes and an assortment of strobe arms, SX and 40mm port extension rings, Kenco 1.5 X teleconverter, Q40 torch, , various strobe snoots, magic filters.
Previous lenses used:
Nikkor 18-55 f3.5-5.6 AFS DX
Sigma 18-50mm f2.8 EX DC macro
Nikkor 105 f2.8 D micro + Nikon 4T dioptre
Previous digital cameras:
Digital photograhy started in 2004 with Canon Powershot A80 and A95 models inside Canon underwater cases, together with Inon wet fit lenses: UFL165AD fisheye, UWL105AD wide angle, UCL165AD macro.

.
A Nikon SLR was first used underwater in 2006 with a Sea & Sea housing - firstly the Nikon D50, shortly followed by a D80 - and now the D90.
There are no longer any images on this site taken with film but prior to digital cameras, underwater photography had been exclusively with Nikonos 111 film cameras. A number of these cameras were used for 20 years from 1983 through to the end of 2003.

Surface Photography:
A Canon Powershot A710 IS camera is used for many above water shots when an SLR is unavailable. Recently, a Sony NEX-5 + 16mm lens has been added to the equipment arsenal.
