A few shots from my recent trip to the Sound of Mull, Scotland. This was the first "full" week I've had diving with the new camera setup, and I'm pretty happy with how the shots have turned out. Only problem was that I couldn't use full manual on the strobes (bit too fiddly with 5mm gloves in cold water), so these were shot TTL. Experimented with inward lighting techniques, and tried at darker backgrounds. All shot with Oly EM-10/Nauticam housing, with twin Z240 strobe (0.5 diffuser), 9-18mm lens or 14-42mm lens. Comments welcome.
Typically, I use my wing for buoyancy, and just take the squeeze off with the drysuit. I normally open all valves on descent, then when I'm almost at the bottom shut the drysuit constant volume dump valve (autodump), then open 1/2 turn. I put enough air in as I descent to take of the squeeze, but then regulate my depth on the wing. Make sure your zip is well lubricated, and doesn't catch on the undergarments, and don't pull directly on the neck/wrist seals especially if they are latex - my friend was in a hurry to dive once and did just that - result - ripped neck seal and a missed dive for him.
It shouldn't take you more than a couple of dives to get used to it, just make sure that you do a weight check with the new suit as it will affect your buoyancy, especially if your wearing a thick undersuit..
Speaking as a UK diver who dives year around when the warmest it gets in the UK is ~18/19C a drysuit is a must for a comfortable dive if your doing longer dives or multiple dives in the same day. If your doing just one relatively short dive a day, you can probably get away with a suitable wetsuit. For sheer comfort however, a good fitting dry-suit is a must. After 15 years of diving, 14 in a drysuit, i certainly wouldn't dive in a wetsuit in water that cold if I had a choice! Drysuit all the way..
