#357982 Sipadan is a protected* area

Posted by tdpriest on 18 February 2015 - 03:03 AM

... there isn't a maze, the cavern is large; and there is a tiny but visible window which I think anyone can locate...


There is something of a maze, if you go right on entering the large cavern (although Cousteau certainly managed to make it look more impressive than it is, I'll grant). It has silted out, sometimes if a turtle or fish is trapped inside. It's a proper cave dive, and needs a line...

#356822 Dry Suits - How to?

Posted by tdpriest on 21 January 2015 - 05:38 AM


Perhaps there is something unusual about British divers that causes the fatality, but in reality, a rapid ascent is a manageable event... as long as there is no pulmonary restriction.


Unusual? The British Sub-Aqua Club has long cooperated with the police, hospitals and decompression chambers to investigate diving deaths in the UK, if that's unusual. One thing that became clear many years ago is that there's a world of difference between a planned rapid ascent in training and one made in an emergency, particularly if there is a regulator failure or, heaven forbid, an out-of-air situation. I think that you're dangerously sanguine: how many burst lungs are too many? I also think it's silly to distinguish between the rapid ascent and failure to exhale: they are, of course, two sides of the same coin.

It's always too difficult, so, as usual, I'll cheat. One from Truk, one from the Red Sea and one from Raja Ampat:

#355561 F'n Stop - big rookie mistake

Posted by tdpriest on 18 December 2014 - 05:33 AM

... shoot manual, that way you must remember to actually control the camera.  Or said differently you can then screw up the shutter speed and ISO too...


I used to jump in without flipping up my camera's flash, when using optical cables...


... but I've done all the rest, including not zipping up my drysuit...


... I had to buy a Nauticam to fix the problem! Have you seen the Nauticam wet underwear alarm? It's great for dry diving!

Thanks, again, for your advice, encouragement and hard work (even if supplies of Diet Coke ran a little low)...

#353672 Dry Suits - How to?

Posted by tdpriest on 24 October 2014 - 11:19 AM

Personal choice this. I find no issue with keeping a track of my buoyancy using both drysuit and wing.


I have to disagree. In the 1980s a number of British divers drowned, tipped over and held head-down when making shallow-water entries or exits with over-inflated drysuits, but there are also rapid ascents, caused by confusion between drysuit and BC, that are equally dangerous.


And if the thing does get away from you, relax and enjoy the ride... just breath fast on the way up! :)


And that's just stupid, I'm afraid. Many British diving fatalities are associated with rapid ascents.

#353619 Getty invite

Posted by tdpriest on 23 October 2014 - 05:08 AM

Dear all,

I just got the Getty invite on Flickr to sell some images. Would you do it?



Your images are much too good for Getty, on those terms.


Even I didn't like them, and I've only ever sold one image!

#353378 Dry Suits - How to?

Posted by tdpriest on 15 October 2014 - 03:21 AM

It will be 10m/33ft MAX so not too much to go wrong.



Unfortunately, that's completely wrong. Shallow dives are where drysuits are at their most difficult. Small vertical movements result in large changes in bouyancy; the suit is much easier to drive below 10m...

#353123 Bali Trip Recommendations

Posted by tdpriest on 01 October 2014 - 05:18 AM

I remember Tim and Alex had a roving rhino issue a few years back! :D . The Tulamben beach shoreline is lined with smooth rocks, some pretty large, which makes it difficult for ingress and egress for shore diving with a big rig and gear, especially when the waves get a little choppy... 


... and someone may have the photographs of me falling over with my Nauticam rig to prove it! I recommend leaning on your partner and both putting on and taking off fins in 3-4 feet of water...


... boats are best!

#353036 Bali Trip Recommendations

Posted by tdpriest on 28 September 2014 - 04:09 AM

Just remember that creatures move around and that "here today, gone tomorrow" is the rule: good guides are a godsend! Mantas (and Mola mola) are unpredictable, and you can spend a lot of time for little photographic joy: on an 8-day schedule I would think hard about giving them a miss. 8 days isn't even long enough to do Tulamben justice.


Here's what I found in Tulamben (Scuba Seraya) and Menjangan (Mimpi) a couple of years ago.

#352636 Fabien Cousteau to Conshelf II, spots available for trip this March

Posted by tdpriest on 17 September 2014 - 04:15 AM

Should be a great trip!



Why? There's not much left, and not so many fish...





... and flying in to Port Sudan can be a nightmare.


However, the Umbria is still a great dive and the Sudanese reefs are less damaged than those near to the Egyptian resorts (although, even there, there are gems).

#352018 How to shoot like Japanese UW photographer?

Posted by tdpriest on 26 August 2014 - 03:24 PM



As we know, classic macro photo is with black background,

But this style is not popular in Japan.

Probably because they don't have volcanic soil habitat like Anilao or Lembeh,




The "classic" black background is created by a high shutter speed and a high f-stop, the image relies on strobe lighting. It hasn't got anything to do with the colour of the background, because it's best shot against the water rather than the reef.

The light, unfocussed background relies on ambient light, slower shutter speeds, wider apertures and balanced strobe lighting. It's harder to do. I often find that my backgrounds are too dark.

#351821 Malaria

Posted by tdpriest on 20 August 2014 - 04:25 AM

Prevention is the key.


And cerebral malaria the outcome...


... if you're unlucky.


Protection and prophylaxis because, yes, dengue fever is nasty, too.


I am not a doctor and don't play one on TV


Nor is anecdote a substitute for evidence. The advice from colleagues in Infectious Diseases Medicine is protection and prophylaxis. I use malarone where it is appropriate because doxycycline is substantially more unpleasant in my experience.


I'm pretty sure that this conversation recurs on Wetpixel every couple of years.

#351819 Best printing techniques

Posted by tdpriest on 20 August 2014 - 04:06 AM

... what aluminium finish is best for underwater images.


Has aluminium ever improved a good image? I know I'm talking like a pompous purist, but a heavy matt white paper and only moderate colour saturation is my preference for a good image.
