  1. Brings back good memories! Adelie's are just ridiculous birds .
  2. Richard - Check out IDimager. A very full-featured program, expanding on a lot of functionality that iView Media Pro and Expression Media provided.
  3. COSMOS? To put this all in perspective, the deflection you list is 0.17% of the dome radius (not 1.7% or 17%, but less than one-fifth of one percent). That's a very, very, very small deflection. I'd be curious to know if port manufacturers are even able to guarantee tolerances that low between production runs...
  4. The previous 100 macro (non-IS) was fixed barrel (internal focusing) as well.
  5. (Direct gallery link if you prefer to skip the text: Eastern Fields, Papua New Guinea) Eastern Fields is one of the best wide angle locations I have dived, flush with dense schools of juvenile reef fish through adult pelagics. The Wetpixel group was sure there could be a good amount of critters, as well, but we so rarely decided to use our macro lenses. Gorgeously healthy reefs featured some superb thermoclines during the daily current fluctuations; in the rare spot that wasn't covered by living coral or fish, the current blows past your head with the roar of a strong wind, and endless anthias fight upstream in the breeze. Friendly potato cod pose for pictures at 120 ft, and a very unique wreck contains hundreds of flashlight fish that burst forth from a bulkhead as darkness falls. These bannerfish at first mistook the tiny exhaled bubbles from my regulator for food, chasing after and gulping them down. They soon realized the bubbles were not the plankton they desired . Reef sharks were curious and cooperative, approaching divers repeatedly to investigate the strangers encroaching on their territory. Algaes, corals, sponges, fans, fish. What more to ask for? Self-portrait with a large potato cod I've yet to caption anything, but I managed to piece together a gallery from the expedition (new recent record for me, seeing as how I'm still two years behind on some trips): Eastern Fields, Papua New Guinea. Special thanks to Eric Cheng, Tony Wu, and Craig de Wit for the organization of the expedition!
  6. (Direct gallery link if you prefer to skip the text: Eastern Fields, Papua New Guinea) I recently returned from the Wetpixel expedition to Papua New Guinea, and Eastern Fields is one of the best wide angle locations I have dived, flush with dense schools of juvenile reef fish through adult pelagics. The Wetpixel group was sure there could be a good amount of critters, as well, but we so rarely decided to use our macro lenses.

As always, I appreciate any feedback/criticism of the gallery images. Special thanks to Eric Cheng, Tony Wu, and Craig de Wit for the organization of the expedition!
  7. I guess the third frame to add would be a natural light 'Magic Filter' version of the scenes to show how we still do see color, even as blue begins to dominate. Slightly more difficult to get all three shots at once, though!
  8. If you keep your camera set to motor-drive, you may end up with photographs taken in the moment between strobe recycles, with dim foregrounds and dark silhouettes. I used to flag the accidental captures as destined for the trash, but recently, I've found a more useful purpose for the otherwise unimaginative images. In animated GIF format, they can quickly convey to friends and family just how the underwater environment could appear if not for our artificial illumination. A few samples from the recent Wetpixel expedition to Eastern Fields, Papua New Guinea: Perhaps others might have similar examples they'd be willing to show off?
  9. Capture the viewer with eye contact. Weigh isolation (depth, lighting) and detail. Minimize distractions. Do you see a message in the image? What's the take-away? My feeling is similar to Mike's comments...
  10. Conjecture from the trip: it should be a FoV and spacing issue, and should work with a 100mm macro on FF, with just the slightest loss of coverage (100mm FoV versus the 96mm equivalent for the EF-S 60mm that the UFL-MR30 is matched to). I imagine Nikon users will lose more coverage - their only comparable FF lens is a 105mm?
  11. Why use it anymore? Start key. Type whatever you were going to do. Hit enter. Or you can be slow...Start key. Type "run". Type whatever you were going to do. Hit enter. Or you can be really slow and enable the Start menu "Run" item in customization options, of which there are many...but why? Aside: I would suggest the majority of all BSODs are caused by using the 'Upgrade' option between operating systems (WinXP->Vista->7) instead of doing a clean install...wipe that old system out entirely and start new. You'll be much more stable...
  12. Not really - the 1D has always been 1.3x crop. The 1Ds IV (FF) won't be out for a few months...
  13. Nice of Canon to preserve the body shape . Canon 1D Mark IV (Canon Product List Specifications): http://www.usa.canon.com/consumer/controll...p;modelid=19584 Sample images: http://web.canon.jp/imaging/eosd/samples/eos1dm4/ Rob Galbraith overview article w/ side-by-side image comparisons with Mark III body: http://www.robgalbraith.com/bins/multi_pag...d=7-10044-10310
  14. I've switched to OSX (Leopard and then Snow Leopard)...and then back to XP SP3/Windows 7 x64. Windows 7 is a major improvement, and I'd hold on any decision until you have a chance to play with it. Some thoughts: If you'd prefer to use specific software only available for OSX (Final Cut Pro, Aperture, etc), then by all means go with Apple. My own decision was driven by the fact that, for comparable hardware, most cross-platform software seemed to run faster on Windows (Adobe, Canon, MATLAB (benchmarked 2x faster)), not to mention engineering-specific applications that are only available on Windows. Boot Camp/Parallels is a poor option when attempting to maintain a RAID array for media storage, as neither side reads the other's format, restricting file access unless you're willing to copy to a temp. folder. I agree with Jeremy - if people other than yourself are going to be using the computer, and you'd prefer not having to follow the Tech Support Cheat Sheet, then you may be better off with an Apple. But, you may have to follow it then, too . YMMV.
  15. Both of those teleconverters' manuals warn of issues with the older Canon 100mm macro lens. It seems they're just now being realized with the new version...
  16. http://blogs.adobe.com/jnack/2009/09/a_few...with_ps_sl.html Latest version of Canon's DPP crashes as well by default.

    I know exactly what you're referring to, and we'll look into seeing how it might be implemented .
  18. $1049 MSRP. How much sharper can they make that lens? I take that back - the new MTF charts are obscene. Beating out the superteles...
  19. You'd think Apple would've worked to make it easier for developers to access preliminary builds so all these issues could be resolved before the public release. Looks like NTFS-write was taken out of the golden master, as well? Could've used a few more weeks to polish...how long before a hotfix is issued?
  20. Hey Dave - did you guys make it back to Schmeider Bank? A site to remember...
  21. If it is a processor limit, it should be an easy thing to test - run the same subjects at maximum frame rate limited to 7/8/9/10 fps, and look for a significant crossover point where percentage in focus drops off sharply.
