For those of you vaguely interested in this kind of thing, I use a Pentax K5 digital SLR.
I've owned a number of Pentax cameras and I'm a big fan of them. They're extremely well put together, built for the outdoors and very solid indeed.
The K5 not only delivers excellent picture quality (better than the Canon 5dMk II or III - source Dxomark), but is also fully sealed and weather-proof, useful if you spend a lot of time in the sea in the pouring rain/snow, waiting for the light.
I also like the fact they're backwards compatible with 30 odd years of quality Pentax lenses, and, as you might expect from a lifelong supporter of NUFC, I've always been one for the underdog.
To go with it, I use a Pentax DA 10-17 f3.5-4.5, a Sigma 10-20mm EX F4.0-5.6, a Tokina ATX Pro II 28-70mm f2.8, and a Pentax M 75-150 F4. I also have a number of Pentax primes: FA 50mm F1.4, FA 35mm F2, FA 28mm F2.8, A 20mm F2.8, and a fully sealed and weather-proof Pentax DA 18-55mm WR MkII for when it's wet.
I carry two 10 stop and 7 stop B+W neutral density filters, a 10 stop Lee Big Stopper, and a set of Lee nd grads..
I also carry a Pentax K01 for the unexpected, and an oldschool Pentax 645 medium format film camera for special occasions - very big, very heavy, very exciting.
Most of my photographs are taken at the extremes of the day, first or last light, dawn or dusk, usually with long exposures, sometimes up to 3 or 4 minutes, and occasionally beyond.
I don't use any coloured or tinted filters.
Wherever I can, I shoot RAW and convert to JPEG.
For post, I use Adobe Lightroom. No smoke and mirrors, just your basic post processing: brightness, contrast etc..
I have one principle: catch it in the camera, whilst remembering how it felt to be there in the first place...
