#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.

#345896 acrylic vs. glass domes

Posted by tdpriest on 09 April 2014 - 05:50 AM

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.

#344204 Critique Please - I love this shot. Am I crazy?

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...

Try posting on the FB group Cal



Not mad keen on Facebook...


... like many who have a professional presence outside the underwater world.


I have been disappointed with the migration of so much away from what I still think of Wetpixel proper.

#343668 Wet Macro Lens Comparison

Posted by tdpriest on 22 February 2014 - 04:36 AM

The Fit diopters are of intermediate strength and easy to use...


... just to add more to the mix!


Fit +8D (equivalent to Subsee +5D) with step-up adaptor:

I like the combination of a teleconverter and the option of greater magnification with the wet diopter. I think it's a good idea to set up for supermacro and not to switch between 1:1 and supermacro on the same dive, although the macro lens and the +8D don't change the setup and mindset too much. I do believe in planning the shot and diving the plan, if possible. My planned shots are definitely better than my opportunistic efforts...


... I really wouldn't start with a +10D Subsee: it's too big a step, too different a technique and the learning curve is very steep.

#342835 New website

Less is more!


I would think hard about using a really strong image on the home page, moving your biog to the inside and also putting the galleries inside except for, perhaps, a small (20-30 images) portfolio that sells your style to the browsing public.


I like Rob Bailey's gallery, but perhaps I shouldn't talk because I've never put my own images into order...

#342495 Whale Shark Slaughter

Posted by tdpriest on 28 January 2014 - 08:19 AM

They are clearly taking juveniles, too. Cutting the whale sharks' throats to spite their own, destroying the giants to satisfy a very short-term greed.




Even as a tourist spectacle, whale sharks are magnificent:

#341411 Post processing every time?

Posted by tdpriest on 04 January 2014 - 05:03 PM

I want to achieve great photos straight from camera.


A great ambition, but one confined to transparencies in the days of film. Darkrooms have been part of photography for most of its existence, and are fundamental to photography as art. I learned how to shoot by working in a darkroom, by seeing what worked in the negative.


Morten is right in two ways: the better the image in the camera, the better it will be when projected, printed or seen on the screen; he's also right  to say that learning to make those excellent images requires a lot of practice.


I would point out that some of that practice can be in front of your computer.



A parting thought:

#341369 Testing ttl strobe accuracy on a film camera?

Posted by tdpriest on 03 January 2014 - 08:15 AM

The YS-D1 with a Nikonos sync cable certainly does ttl with a Nikonos, this should work with the F100 as well...


I'm surprised: this isn't noted on the Sea & Sea website. It would mean being able to switch between different circuits on the strobe: how do you do that?

What camera and lens(es) are you using? The exposures and focus look good, but the composition and framing are a bit off.

Hello all! :uwphotog:
