Wow - I have always wanted to dive with these beauties, the octopuses in the Med and Asia are such - well.... pussies. Great shots and experience. Definitely on my list ....

Actually as you may know the RX100 has a WB function that is a bit clunky, but it seems to work OK now I understand it better. So the answer is that as I didn't have a white slate on me for this casual dive I used a saved 'custom' WB setting that was taken some time ago on a white slate in a completely different environment (clear blue water in Indonesia - lol). The custom WB screen tells me it is 9900K but actually it looks a lot hotter than that as the C.Temp./Filter option on the RX100 when set to 9900k looks less red. It may be that 9900K is the max reading the RX100 registers. What took me a while to find is that there is a little square color chart that you can open up by pressing 'down' on the option ring in any of the WB choices, and then one can tweak RGBM etc.

 

If you don't have an RX100 then all the above will make no sense at all! So basically I used an old slate setting as really I didn't have anything else. I'm sure it didn't make much difference anyhow as there are not a lot of rich colours in any of the shots.

 

Haha - sorry for the long winded answer :)

Ya it's always worth a dive, like so many wrecks you never know quite what you'll get. The Brisbane is not quite like diving Truk Lagoon but it's wonderfully preserved with plenty of swimthroughs and fish/macro life - also it's only 5 minutes off the coast where I live! :)

Frankly I'm blown away by the video quality that this matchbox sized (well cigarette pack sized) camera produces. At full 1920x1080p on a big LCD screen these images are stunning. I'm doing a little more editing right now and will post in due course. I'm new to Vimeo, but glad to see that they have an HD option for viewing.

I was using max resolution, max frames, progressive AVCHD (1920x1080p 50fps), aperture priority, (sometimes shutter), tracking focus and a white balance based off a white card.

 

I agree with earlier postings about this great camera that white balance under water is not trivial. I was convinced (before I used the camera on dives) that manually setting the desired colour temperature would be the way to go, but this did not give very good results in the field. I used a white card and then further adjusted towards red or blue etc with the little square colour chart you can open up. Thankfully you can see the results visually as you adjust. I did get an 'error' message on some white card readings, but kept the resulting WB which seemed to be fine.
