  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

The Gentleman's Underwater Bubble Blower Thread

For very important conservation projects, and especially with critically endangered species and habitats, I will work pro bono.
 
One thing to consider if you are working as a professional underwater camera operator or DP in Australian waters or for an Australian company is that you should be working under Australian Standards 2299 and should be certified under the ADAS 2815 certification at the very least level 1 or such things as insurance and public liability will come into question if there is an accident on set or location. This has ramifications in regard to workplace health and safety in a legal sense.
 
Further to my post Ross, the destruction of the Great Barrier Reef continues unabated, the largest living ecosystem on this planet, now 90 percent under threat of extinction, a most alarming statistic confirmed by some of the foremost marine biologists on the planet; climate change, ocean acidification, coal interests, Asian fishing fleets, perhaps time to leave aside lawyerly questions of public liability, perfunctory Australian Standards established by bureaucratic desk drivers, and concentrate on what is vitally important.

Without wishing to make it personal, your continued employment depends, completely and without reservation of any kind, on saving the GBR from destruction.
 
Your getting a bit hysterical Tom ;-) The workplace health and safety regulation are there to help protect people from unthinking and uncaring producers who take advantage of some divers. Yes we have had an enormous coral bleaching event but to say that 90% of the GBR is under threat of extinction maybe an exaggeration. To say my continued employment depends, completely and without reservation of any kind on saving the GBR is certainly untrue as I can always work in a swimming pool lol.

Given the discussion on rates, sometimes it seems like there is more money in shooting in the swimming pool ! :wink5:
 
"Aerial surveys in April confirmed 93% of the Great Barrier Reef had been hit by the bleaching to some extent. The northern section, which because of its remoteness had endured as the most pristine, copped it the worst. Last year, this area of the Reef was credited with saving Australia the indignity of its World Heritage treasure being declared by UNESCO as “in danger”.

“Australia argued to UNESCO that the outstanding universal value of the World Heritage area is intact because we have this northern 30% of the Reef where everything is hunky dory,” says Professor Terry Hughes, director of the ARC Centre of Excellence for Coral Reef Studies. “That is no longer the case. In the space of a month or two, the northern third is now more degraded than the southern two thirds.

Anyone lucky enough to have UW cinematography as their sole means of income, and that is just a very few folks, has my respect. :cheers2:
 
Some 8K VV and Canon Lens Feedback, tested with Standard EF Mount:

8-15 /4L - Cutoff as expected until 15mm. At 15mm and minimum focus there is cutoff in all four corners, but that is gone as focus is racked to 12", and shouldn't be visible in underwater shooting situations with common domes.

11-24 /4L - Slight Cutoff on left and right sides at 11mm. Gone at 12mm, and I suspect this may actually be from the mount.

Zeiss ZE 15 - No issues

Zeiss ZE 21 - No issues

Zeiss Otus 28 - Not wide enough for many underwater situations, but 4k playback from 8k (with smoke coming out of my Rocket-X :smiley: ) made my jaw drop.

Stay tuned for Helium feedback, initial results are very promising.

Mark, I seem to recall a line of T-shirts you were flogging at one point, we all do what we have to do to put food on the table for our families.

Wind your neck in mate, I wasn't addressing you, simply agreeing with Mauricio's point.

I have a feeling the results from that 8-15 and 11-24 (and maybe even the Tokina 11-20) are going to be stunning.

Does it look like the mount could be modified to eliminate the cutoff at 11mm - by the user or by Red making a modified mount? 11mm on VV/full frame would be pretty awesome - I think that would be significantly wider than even the Ultraprime 8R on S35.

I think 12mm is wider too but when things get hectic underwater it is always a hassle to have to make sure you are slightly zoomed in. It's always nice to have the ability to go all the way. (been saying that since I was 17-oops, sorry wrong subject:wink5:)
 
Check out Phil Holland on Facebook, a new mount exists, and to my eye it looks substantially wider. All is good on He, only VV shows some issues that may (or may not) be mount related.

Titan X in the box, and 8K Helium is still only playing back well at 1/4 res. Another one should be here on Monday...

I am definitely seeing a cleaner image into the shadows with Helium than I have seen with Dragon. This might even be a bigger underwater release than some of the recent advancements. As a rule, we have to under expose backgrounds to maintain pretty blue water. This means that any foreground that can't be fried with artificial light is going to be more under exposed than ambient blue, and by extension noisy. Helium looks to be significantly less noisy in those situations.

To be clear, this isn't an A7S. It doesn't see in the dark. But when it does see, it sees so much more... As of this moment I have only mounted STD OLPF, but I look forward to seeing what I can squeeze out of STH.
 
Yes new VV version of the ef mount is available for VV owners. Addresses the ultra wides.
 
It is a real shame that some members on this thread get so confrontational. Maybe many of you are quite competitive and have pitched on the same jobs and there is always a winner and a loser and this causes a clash but I have read plenty of posts in this thread that disappoint me. Human nature I guess.

Jarred,
Thanks for the information on the new mount for VV, awesome news. Will that be released in both Canon and Nikon mounts? Thanks again for the post and the info on the upcoming goodies. Always helps in the ever changing world of the kit.

I know, I know but it just seems that many of the guys in the underwater world get pretty bitchy towards eachother. Super competitive or something and its a shame. You guys get to do the best job ever and should be supportive of one another. In plenty of other threads in this forum people will happily help others with advice and info without being too childish about it all.
Also, who cares if some people earn other income doing other things. It doesnt change your love for underwater shooting.
Tom, I respect that you would donate your time and passion into projects geared towards helping the planet instead of just chasing top dollar. Should be more people with that kind of attitude. There is a difference between working for free to help advance one persons interest, like when you get cold called by someone you dont know who wants to shoot a short film or music clip with no money, to doing charity work for an organisation trying to make things better.
