#350757 Tips for Underwater Photography Workshop 1st timers

Posted by tdpriest on 24 July 2014 - 06:41 AM



One comment was from a photographer worried about hordes of photographers competing for the same subject.


Many workshops avoid that, by splitting up the group. Alex Mustard, in particular, is really good at organising things so as to stress neither the wildlife nor the photographers.


It would be a good question to ask of the organisers, of course.

The Ferrari's book MacroLife is very good, even if it's officially about Malaysian and not Indonesean creatures. Most of the "critters" are in one book, not the two or three from the excellent Humann/DeLoach series...

#350548 Over expossure

Posted by tdpriest on 20 July 2014 - 06:34 AM

Auto exposure almost always seems to over-expose, at least with of my Nikons, over the years. The EXIF data says "pattern" metering, which has probably completely misinterpreted the scene: spot metering can be better underwater. TTL strobe settings can help, but in the end almost everyone comes to manual exposure and manual strobes for wide-angle images.

I'm pretty sure that you can select the focus point and keep Auto metering: there should be a combination of Menu and camera settings to do that on such a sophisticated camera. I've certainly done that with a D200 and all my subsequent cameras.

I hope I get my turn to dive and shoot there in 2017!


I recommend twin cylinders, a deco mix if you are going to go to 50m+, listening to the guides, and asking them to get you into the wrecks at the head of the queue!


I think I actually benefited from spending a week without my camera, although it felt tough at the time. I got used to the wrecks, and a feel for interesting shots.

I find it quite surprising that there could be a chummed dive at night? Is this true?


I read that the dive was at dusk. Shear Water still, as far as I know, puts out a scent trail from bagged chum that is protected from being eaten in a crate. The sharks aren't fed. Both Shear Water and Dolphin Dream have years of experience with doing this: Jim Abernethy's briefings and organisation are precise, and the crew will pull out divers who are not putting shark awareness ahead of their camera: I know, that was me on my first trip.

... I would encourage the moderator to keep condolences and wishes separate from people seeking to comment on the circumstances of the event...


I agree, even though I've done both. I'm sorry.

#350019 Traveling with underwater camera to international destination - packing tips...

Posted by tdpriest on 08 July 2014 - 11:01 AM

Just remember :bananashark:  : Americans get more luggage :evilgrin:  and can afford the seats that Europeans can't*...

... are allowed two  :deadhorse:  bags in the cabin, and no American has ever  :evilgrin2: had their carry-on weighed (or a 12lb limit), as as is all too common on this side of the Atlantic  :diablo: !


Our guide has to be "take less stuff", or "get someone else to carry it".



* I can't afford 5% of my net income to fly out for a single dive trip, you see.



PS If you want an early myocardial infarction, get stung for excess baggage by Singapore Airlines...

I do like your room mate’s video ...


We were treated to the best organisation, the best briefings and the best advice on photography that I have ever been lucky enough to receive. Ta!

#349522 Red Sea Workshop

Posted by tdpriest on 28 June 2014 - 05:11 AM

In the early summer large schools of snappers, batfish, unicorn surgeon-fish, barracuda and trevallies swirl off the southern tip of Sinai, at Ras Mohammed. Nearby there are shallow reefs and a treasure-trove of World War II military paraphernalia in the wreckage of the SS Thistlegorm.


Alex Mustard regularly runs an excellent workshop based aboard one of several large and comfortable live-aboard dive boats. This year he was joined by Alex Tattersall, demonstrating (certainly not forcing sales on us with his usual skill) new and exciting ideas from Nauticam.


The winds died down, after blowing us away from the shoals of Abu Nuhas, and the diving began:

#348710 Nauticam vacuum leak detector

Posted by tdpriest on 05 June 2014 - 08:22 AM

I think that at the depth where the dome fell off of Tim's housing, the pressure on the dome was considerably greater than 200 g.



More like 2-300 kg! 


The glass parted from the plate, so the dome fell apart: the dome didn't fall off, nor the o-ring on the mounting leak. My guess is that the o-ring above the glass moved, letting the glass shift in turn. The plate has a very thin rim and the glass had a slight chip on the ground surface that may have made a leak more likely. Having said that, the dome had been to 40m and had been on hundreds of dives after failing in a swimming pool and being repaired.


The design of the current dome is different.

I recently acquired a SAGA 4" coated glass mini dome but I have not tried it yet... we´ll see...


Unless you are much weirder than we think, you'll love it!

It may be like a Ford or Chevy question.  No one common answer.


No. It's a Ford or Audi question.

much needed break from the rule of third composition



I hate the "rule of thirds", too. It's a cheap knock-off of the "golden section".


I guess that the Greeks were more civilised than the moderns...

#344202 See unique marine life: chase or not chase?

Posted by tdpriest on 07 March 2014 - 03:43 AM

Don't chase the wildlife. Do more diving.


Nothing else works...
