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.
Please accept my apologies for the (glitch-squared) below...
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.
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...
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 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...
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:
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.
