I do think CFWA is a good option in poor viz. The setup is based on getting very close to a subject but setting it against a wide background. The poor viz alternative is macro. It could be of course that in poor viz the background isn’t great or at least far from ideal. But that doesn’t necessarily matter. I’m not sure about using video lights. But maybe others can comment on using them for WA with a TG. I wouldn’t do it with larger sensor cameras for still images.

I’m the same, got pots and tubes of the stuff all over the place. In 25 years I think I’ve used 3 of those small rounds 1” tubs that are fitted with a key chain.

Hi Hoekma! A warm welcome to Waterpixels. Great to have you with us. Good luck with switch. And your bank balance…. 😝

I’d suggest a periodic rinsing and cleaning of any parts that needs screwing together. Galvanic action, salt accumulation etc can all have a gluing effect. I’d probably do that maybe once a week if diving really frequently

Yeah, on the watermarks there have been loads of posts over the years both here and on Wetpixel (RIP) offering solutions from white vinegar to Coke to a windscreen cleaner to Brasso. I think I’ve tried most of them. I don’t think any of them really worked (including cerium oxide). I’m left with the Chris Ross method. Rinse and wipe.

Sounds like a very thorough job! A bit like Dave's approach, I only remove and clean the port o-ring if I change the lens/port. If the seal is good and I'm not changing lens, I leave it in place until diving is done for a while. If I'm diving in a sandy environment (I'm thinking sandy shore entries), I'd probably check, remove and clean the housing o-ring IF I had to open the back. But if, say, liveaboard diving in reasonably clear water, I'd check the o-ring visually if I open the back. But, like, Dave, would likely leave it in place unless I could see debris on it. Slackening off the arm clamps during rinsing is important, I think. My partner didn't release a clamp over several months and it was the devil's own job to loosen it. Watermarks on ports are a pain. A comment @Chris Ross made some time ago had me wiping ports down after rinsing them - good tip I thought. I have tried using denaturalised water after rinsing but came to the conclusion it made no difference and that water isn't cheap.

Hi Stephen A warm welcome to Waterpixels. Really great to have you with us. We hope you enjoy the forum. Best wishes

Hi Adrian I've just bought an OM-1 to replace my lost D500 but havn't yet got it underwater - not even into a housing! I'm intrigued though that you compose on the LCD screen rather than in the EVF. Is there a reason for this?

Hi! I’m not even going to try to type your username! Great to have you with us. A warm welcome to Waterpixels. Best wishes

Hi hamsteRfury If you’re looking for advice on this, it’d be better to start a new post rather than continuing in this thread. More people read and respond in the Technique forum rather than in this one which is essentially for new members to introduce themselves and is part of our anti-spamming system.

Hi Jock! A warm welcome to Waterpixels. Great to have you with us and congratulations on the retirement. A long and happy one I hope. Best wishes

Hi Kevin! Great to have you with us. A warm welcome to Waterpixels. I suggest you start a new thread with your question under the appropriate forum as that’ll get more views than here in the Members Intro thread. Best wishes.

Greetings from a fellow Northener and a warm welcome to Waterpixels. We hope you really enjoy the forum. Good to have you with us.

Hey Tora! A warm welcome to Waterpixels. Great to have you with us. We don’t have many members in China so you’re extra welcome! We hope you enjoy the forum. Best wishes
