  1. I've used the WACP with 28-70mm on several trips over the past year and am impressed with its versatility of FOV range. I believe that is about as close as you’ll get to having your cake and eating it; for now, with full frame. Some examples. At the narrow end (70mm->75degrees): http://www.underwaterdisplay.net/dive63/FJ190513_3215.jpg http://www.underwaterdisplay.net/dive63/FJ190514_3382.jpg At the wide end (28mm->130degrees): http://www.underwaterdisplay.net/dive64/MOR20191007_5670.jpg http://www.underwaterdisplay.net/dive64/MOR20191004_4678.jpg Downside is weight in lugging this beast down a beach but once in the water it’s a thing of beauty. In Moorea recently we did a lot of swimming in the blue and there wasn’t much difference in water resistance (possibly less) between my rig and those using large domes.
  2. https://vimeo.com/89280331 The starry toado (pufferfish) baitball encounters are rarely captured - these open water visitors don't last long after being blown in by easterly winds as snapper quickly decimate them. Rikoriko cave is claimed to be the world's largest sea cave - by volume. Northern Arch, known for its squadrons of sting rays soaring the currents. Middle Arch, another of the many arches which contribute to making this island group such a visual feast. And to think that if this had not become protected over 30 years ago there would be little left to experience of the amazing moving window of marine life. Enjoy, Colin
  3. It's a self built quad - a little larger than a Phantom, waterproof frame and more stable in windy conditions. https://vimeo.com/71177626
  4. https://vimeo.com/86675525 The Fiji Siren has been operating in Fijian waters since October 2013. I enjoyed a seven day cruise in the following month (voyage #4) and again early this year;16-26 January 2014 in hot summer weather and glass calm conditions - one of the most enjoyable live-aboard trips I have been on to date! This short video provides both top down and underwater perspectives. The ten day trip route gave the opportunity to spend time at many of Fiji's best dives sites; offering everything from big fish and cetaceans through to macro critters. Areas such as Nigali, Namena and Rainbow Reef would be difficult to collectively cover from land-based operations; particularly during a ten day window where the nights are often used to travel from one location to the next. The comfort and convenience of this well run live-aboard provided excellent opportunities for photography and diverse underwater experiences. It’s a somewhat dreamlike feeling waking up in the morning to a new dive location and time passes all too quickly. All footage was taken using the Fiji Siren live-aboard boat as a base. Video was shot with GoPro Hero3 - mainly under a quadcopter with both 3-axis and 2-axis brushless gimbals. No post stabilization used on the aerial footage. Stills (macro and wide) were shot with Nikon D7100 in a Nauticam housing with Ikelite DS160 strobes. All video processing was done using GoPro Studio 2. Still images were imported into GoPro Studio 2 after resizing and downscaling. Music by 3 Theory, ‘As We Go’. More images at: http://underwaterdisplay.net/dive52/ Colin
  5. Thanks Chris and Phil. Since results may vary using the same port size across different brands of housing (because of minor variations in the port focal node distance), I'm particularly interested in feedback on use experience with the specific combination of Nauticam Nikon D800 housing with the Zen 200mm and Zen 230mm domes. I currently get passable results on DX sensor with the Tokina 10-17 and 180mm dome. Colin
  6. If you've used both ports: Zen 200mm and Zen 230mm domes on the D800 Nauticam housing with Nikon 16-35mm and Sigma 15mm lenses I'm after your feedback... Can I get away with the smaller of the two ports? Obvious factors to me are price and portability but are there significant differences in UW image quality in relation to sharpness, edge sharpness and other factors? Thanks, Colin
  7. I recently received a copy of the book accompanying the series and am impressed by the overall quality. Hardcover, 312 pages: Life: Extraordinary Animals, Extreme Behaviour (Hardcover)
  8. The project I'm about to embark on requires the use of InDesign CS2 (on Windows) rather than the more recent versions. This is due to exchange of files and the legacy edition my counterpart is using. I'm having some difficulty sourcing this older version; in particular the Windows media kit. Adobe are willing to issue me with a downgrade license and are of course happy to sell me CS4; however, I specifically require InDesign CS2 on Windows. If anyone would like to find a home for an unused plus uninstalled version of Adobe InDesign CS2 for Windows OS which is surplus to their requirements (and which has not been used for upgrading to later versions) please let me know. I'm located in New Zealand. Thanks, Colin
  9. Thanks for the entertaining read Looking forward to seeing the images. Dive safe, Colin
  10. Ken Glad you have made it out to the Knights - it's definitely something special! I believe your images are of the following. The moray is a grey moray eel (Gymnothorax nubilus) - each eye has a grey horizontal stripe. The "corals/anemomes" are zoanthid polyps. The nudi is a Tambja verconis. The blenny is a crested blenny (Parablennius laticlavius) although more fish of this type encountered here are triplefins (there are more species of triplefin in NZ waters than anywhere else). Conditions recently have been excellent with very good vizibility. Water temp at the moment is 20C / 21C - I'll be out again tomorrow. More from last week: http://www.gans.co.nz/dive/dive37/ Cheers, Colin
  11. I have just completed a brief dry test with positive results (33 images). Histograms appear reasonably consistent prior to light fall-off. By contrast, in manual mode complete overexposure occurs from f8 thru f4.5 (Tokina 10-17mm @ 1/125). It will be a couple of weeks before I can test this fully in water but initial results do look promising. Colin
  12. Sure Craig Results varied across the exposure range from complete blowout at f3.2 to underexposure at f22. In contrast, a Nikon SB800 Speedlight light on the same subject gave consistent / correct exposure throughout this range. When the TTL unit was rotated to manual setting the strobes worked fine and I was able to use them manually for the remainder of my Solomons trip. Ikelite were very attentive to our issue and the units were replaced. Once I am able to test I'll report on results. Cheers, Colin
  13. Both a friend of mine and I have one each. We are using them with Nikon D200s; one on a Sealux housing, the other on a Nexus housing. Both with DS125s. We initially received these about a month or so ago but had to return them due to malfunction. We have just received their replacements and we are in the process of testing. Cheers, Colin
  14. Sealux offered me two wiring options for their Nikonos style (flexible pin) port: one with only two 'active' wires connected, the second with all five pins wired. I chose this latter option and have found it works fine with 2 x Ike DS125 strobes on manual settings. I believe that the cable required for this setup would be Ikleite part#: #4104.32. This is the 'blue band' cord, 'Nikonos connector to two SubStrobes'. I also found that I could get their original, non-digital cord (I have one of these too) to function by blocking the contacts as described on the Ikelite website although this is not a particularly elegant solution. Here's a wiring diagram for Sealux with all 5 pins connected: http://www.gans.co.nz/dive/rig/NikonosWiringPOC/image004.jpg Colin
  15. Let us know how you get on with differing thicknesses of cable. I would guess that a thicker multi-strand cable will be more flexible and would be interested to hear how it goes. I've been using a single housed SB800 for a while and have got a relatively good hit rate on exposure using iTTL - good for close up / macro although the light is a little cold. I don't believe that iTTL will work with an SB800 / Inon Z240 combination as the strobes need to be configured as master / remote and talk on specific channels using iTTL protocol. The Z240 cannot be configured in this manner. I'm not sure about setting the SB800 to traditional TTL but think not. I'm looking forward to seeing results from the Ike iTTL converter. Colin
  16. Sure! I've uploaded some images which should give you a fairly good idea of what I did. See: http://www.gans.co.nz/dive/SB800_Dual/MoreImages/index.htm I found that fixing self adhesive velcro to a plastic board (I used an old diving slate) gave sufficient firmness to stop the cable from moving too much. I sanded down the top of the plastic nut once it was firmly mounted to make it flush. Cheers, Colin
  17. Arnon, sorry but I'm not sure if I understand your question. By "receiving item" do you mean the mount for the remote housing cable? If so, the mount which I have had success with is an item which I made rather than purchased. I can provide more detail if this what you require. Cheers, Colin
  18. I agree that a thicker cable may be more manageable underwater. The thinner cables should however transmit sufficient light - poor viz should have no effect since the light transmission is via the cable, not through the water column. Jacketed Endglow Fiber is probably what you are looking for: http://www.fiberopticproducts.com/Jacketed.htm
  19. I have also experienced poor results with Fantasea cable. In my use of two SB800s I made up my own mount which positioned a single strand fibre optic cable directly facing the strobe light source http://www.gans.co.nz/dive/SB800_Dual/image3.htm and on the other side directly facing the remote strobe sensor. http://www.gans.co.nz/dive/SB800_Dual/image2.htm This worked fine; I don't think it would make much difference were spiral cable to be used. Colin
  20. Hi Oliver I believe you are correct, the batteries are NiMh AAAs in a pre-wired heat shrink case and are non-user replaceable (without a soldering iron that is). The charger which I was supplied with for my CX800 housing is an ANSMANN energy ACS 110 traveller. The charger comes with an assortment of plugs for both mains and output and will autosense between 1.2V and 12V. Here's a link to their website for the charger: http://www.ansmannenergy.com/en/index.htm?...2id=&appid= Cheers, Colin
  21. Following a cease and desist email request by Mark from uwimages.org I see that the images have now been removed. Colin
  22. Jack I would be interested to know if the sync cord / Y adapter will allow for both speedlights to work in iTTL mode but I suspect not. My guess is that they would need to be configured in master/remote (commander) mode and I have yet to see a cabled solution to accomplish this. If it does work, please let me know and I'll order a Y adapter. Colin
  23. I'm not aware of anyone producing an off-the-shelf housing for the SB-600. While these may roughly fit in the Sealux and Fantasea housings (the two which I've tried) the controls are inaccessible. The SB-800 speedlights require a fibre optic linc to communicate in master/remote mode underwater. Have a look at this link for the test I did: http://www.gans.co.nz/dive/SB800_Dual/index.htm Cheers, Colin
  24. I stumbled upon a website which has published 2006 winning images from UNDERWATER IMAGES PHOTO COMPETITION ( www.uwimages.org ) with no reference to the originating site or photographers and clearly violating the site's copyright. This must really please the owners of these images to no end ;( See: http://haha.nu/beautiful/2006-underwater-i...inners-gallery/ I further note that images are actually hosted on http://www.fileden.com and must have been copied.
