    Hey all! I wrote a really interesting popular science book, contemplating photography from a brain researcher's point of view. It's called "The Camera And The Brain". More info on this book is here. There is lots of nice underwater photography in it.

     

    The only problem is ... I am still looking for a publisher. Does anyone from the wetpixel community have contacts to publishers interested? Please get in touch with me then!

    Recently, I had a work trip to Adelaide in South Australia and I decided to add a few dive days. I knew a few divers there via my Sydney dive buddies, and the local diving community was exceptionally friendly and welcoming. We did 2 days at the Rapid Bay Jetty, a structure from the 1930 densely covered in intebrates and weeds, and populated by lots of fish, among them the fantastic leafy seadragons. Enjoy! I also wrote a brief essay about the biology of the leafies.

    Hi All!

     

    I just started a new series on getting started in underwater photography.

     

    The first chapter is about the importance of good buoyancy, and how to practice it. Without the skill to remain stationary in front of the marine life to be photographed, no quality shots will ensue. The following chapters, appearing weekly, will deal with everything from chosing the right camera, housing and strobes, to exposure, approaching fishes and finding the right exposure. Enjoy!

    Hi Klaus - I'm stumped on this one. Do you have any other shots of it? Did it have one opening or two?

     

    The only thing it reminds me of is a semi-transparent tunicate that might have gotten swept off its rock. Take a look at some of the tunicates on Sealord's page - http://www.sealordphotography.net/Nature/G...101704897_TuHRV

     

    Thank you for your reply! Unfortunately, this is the only quality shot I have of this critter. The surface texture is indeed very similar of these tunicates. I didn't see any orifices, but it could have closed them down when it go detached?

    Hi Klaus,

    I'm thinking you'll need some way to hold the camera steady. Macro is very tough to shoot without a tripod. You'll need to be working at high f stops to get the largest depth of field you can get. What subjects are you planning to shoot?

     

    Steve

     

    Yes, I was considering that. I have a cheap & small tripod which I am considering to bring.

    Right now in Okinawa there are lots of nudibranchs, I was thinking that these, since they are slow movers, would make a good subject for my 1st steps.

    Best,

    Klaus

    Dear All,

     

    After years of shooting stills, I am hoping to shoot my first uw video using my canon 5D II. I am hoping to capture some macro action, using my USM 100 mm lens. Any tips? Any things I should never, or definitely do? Using a shutter speed 2x the frame rate is something I read here to be advisable. How about the light placement? Right now I have one strong led light rigged to the top of the camera, will that be any good? How about bringing a small tripod with me to place the camera on, or should I weigh it down?

     

    My apologies if I missed any threads answering all of that, thank you for pointing them out if so.

     

    Best,

    Hi All,

     

    I found this unusual organism in the plankton 2 weeks ago, in Okinawa, Japan. Diameter ~ 1cm. I found this during a night dive, ~ 6 m deep, above a sandy area in ~ 12 m. Is this a type of invertebrate larva? It definitely does not look like any cnidarian to me, since there are no tentacles, and neither does it appear to be a salp. What is this? Thanks!

     

    Best,

     

    Klaus

    I've checked a few more sources and the nearest I can find is Trimma tevegae. Maybe this is a juvenile and the blue stripe is not present in juveniles? Some of the images you can see online have a much less pronounced blue stripe than the photo in the Allen book.

     

    Thank you for double-checking. Yes, this goby also hovered upside-down, like T. tevegae, but both the base color, absence of the stripe and type of caudal base spot look different.

    Unfortunately some of the species on fishbase only show dead museum specimen, others have no picture at all.

    Hi All,

     

    My buddy Ingo spotted, and I photographed, this small (~ 4 cm) seahorse:

    http://www.flickr.com/photos/pacificklaus/...57624220993190/

     

    It was found in Okinawa, Japan, at ~ 20 m in a sandy area, next to some sea grass and a large sea cucumber. I have not found it on fishbase, or in any of my ID books (but I don't own Kuiter's books on seahorses).

     

    I'd appreciate help with IDing this one,

     

    Thanks,

    I recently completed my Dsat deep tec course and had the chance to dive to 50 m, with my camera. My Inon Z-240 strobe failed at that depth, in a somewhat unusual manner. I would be interested if anyone else had a similar experience and knows of a solution to the problem. I would also like to find out if what I experienced is due to a faulty individual unit or due to a problem with that piece of gear in general.

     

    I am using a Canon EOS 400D, in a Hugyfot housing, connected via 5-pin cables to an Inon Z-240 strobe. A second Z-240 is used as a slave. The malfunction was of the master strobe. I tested the setup on the surface, and the camera took pictures and the strobes fired, as they had during surface tests and dives during the previous days. At depth, however, after 3 or 4 pictures, pressing the camera shutter did not fire the strobe anymore. The control light was still on (red = charged), but the strobe wouldn't work anymore. Turning the camera and the strobe off, and on again, sometimes convinced the strobe to fire once, but not a second time. After a few minutes of fiddling with this problem I gave up and instead enjoyed the dive.

     

    Surprisingly, when returning to the surface, back at the dive shop, after getting the setup out of the rinse tank, the strobe worked fine again, firing every time I took a picture. I assumed I had miss-set something (though there are not many ways to do that and I am quite familiar with this strobe) and readied the camera system for another dive.

     

    At that dive, again to 50 m, the exact same thing happened: Flawless function at the surface, no firing at depth, again flawless function at the surface.

     

    The Inon Z-240 is rated to 80 m. I had the connector cable break at a previous instance, but then it just did not transmit any signal anymore and had to be replaced. I don't think the problem described here is due to a cable problem.

     

    I'd appreciate any suggestions why this problem occurred and how to solve it.
