  1. I think the DX-1G looks interesting and I'm thinking about carrying it together with my film SLR. Here is part of my blog post on the topic: You can read the full post here.
  2. Photo of a leafy filefish and a lament that a Google search on "behavior leafy filefish" results in aquarium sites. http://radthoughts.com/2007/02/26/leafy-filefish-behavior/
  3. I love Mathieu's shot. Gorgeous animal. But here is the thing... if I showed Mathieu's shot in one of my slideshows I know I'd be pulling out my laser pointer. I'd wait a bit, then you would hear one person whisper to another "look over there, see the eye?". Good Hairy Frogfish shots are hard. Good artistic shots like Mathieu's are adored by other underwater photographers and fans of frogfish. My shot gets an immediate reaction from children (Eeeeeewwwwww!!!!!) but I'm not happy with the image I captured compared to what I saw with my own eyes. Why is that? Is it a depth of field thing with small critters with gobbly gook hanging off of them? Is it really good camouflage?
  4. Oh boy, I didn't expect another species name to pop up. Well, with my untrained eye, Jeff's shots of Octopus siamensis and the various shots of Octopus mototi look like the same species. I'm going with "Octopus siamensis or mototi" until we hopefully find something that describes the difference between the two. Well they are are beautiful and very unique animals and I feel privileged to have seen one regardless of what we call it.
  5. Sometimes a few quick and easy photoshop techniques can make a big difference. I spent about 30 seconds on your crab shot and did the following: 1) Levels: while holding Alt key, moved black slider to right slightly, and white slider to the left (without losing too much info... that is where the Alt key helps) 2) Saturation: increased to 15 3) Unsharp Mask: (local) Amount: 10, Radius: 20 - this brings out larger areas (10/50 for fullsize image) 4) Unsharp Mask: Amount: 80, Radius: 0.5 - more at the pixel level (80/1 for fullsize image) It might be a bit oversharpened but it does pop more now I think.
  6. Hairy frogfish photo on my blog post today (post text is unrelated... attempt at humor about hair removal): http://radthoughts.com/2007/02/12/hair-removal/ I love hairy frogfish but I find it hard to get good shots (at least in my mind). Anyone have shots that really show off this fantastic critter?
  7. I found the following short video clips, all from Lembeh Strait: http://www.oceanfootage.com/stockfootage/O...1ae0405b5c9a0b3 I think the octopus in Okuma's shot is the same as what we see in the footage (and the same as what I saw... sorry, I haven't scanned my slides yet or I'd post it). The one I saw was quite relaxed and did not display the distinctive striped pattern shown in some of the videos. The following says the armspan reaches 50cm, which is about the size I remembered seeing, and some individuals have two ocelli on each side (the one in my image(s) has two, just checked): http://www.environment.gov.au/cgi-bin/spec...ent.pl?id=77080 I'd be willing to bet a drink or two that it is Octopus mototi or a very close facsimile. Mind you, I'd probably be happier losing the bet than winning :-)
  8. This octopus shot was taken on a night dive at Lembeh Strait: http://radthoughts.com/2007/02/01/octopus-tool-use/ I assumed he is a juvenile coconut octopus (Octopus marginalis). I believe the shot is about 1:1 so the bivalve shell he is carrying is less then 2 inches wide. BEHAVIOR: he was walking around with the two sides of the bivalve shell, holding on to both with his arms. One underneath pretty much the way you see it in the photo with a few arms extended out to move along the bottom. The second shell half was dragged along with a few arms until he decided to cover himself up (what you see in the photo). Is this a juvenile coconut octopus? Has anyone else seen this behavior?
  9. I believe this is a "poison ocellate octopus" (Octopus mototi). I also have a pair of shots from Lembeh of one, found by KBR's Ben (divemaster) at site TK2. Very cool :-)
  10. Yes, the post is about a new hominid species, not seahorse. The blog is not terribly focused on any one topic. I basically find something I want to write about and then try to find one of my images that is somehow related... its a bit of a stretch sometimes :-) I like that pygmy seahorse shot. I think the seahorse stands out more when the red polyps are out.
  11. Thanks! I appreciate the kind words :-)
  12. Pygmy Seahorse shot to go along with my blog post about the Hobbit kerfuffle (new species Homo floresiensis): http://radthoughts.com/2007/01/31/pygmy-vs-hobbit/ RAD
  13. I started blogging this week and added a post today including one of my photos and a description of the first time I encountered a cuttlefish: http://radthoughts.com/2007/01/24/first-en...nge-everything/ The target audience of the blog is non-diver/photographer but I thought some folks here might enjoy it. Let me know what you think. RAD
