jeremypayne 0 Posted April 29, 2008 Jeremy. No. I didn't bring my macro lens since I only had time for two dives and I didn't want to fiddle with the housing between dives. Besides, although there are interesting macro formations, no one will know that they are underwater! To get the feel of the place you need wide angle and something to give a sense of scale. I hear you ... I will have a w/a adapter with me - but it is wet-mountable and comes off underwater ... one of the few advantages the G9 has over an SLR setup. As you've just been down that way ... what do you think ... I'm going in June and I'll be staying near Playa Del Carmen in Mayakoba. Should I: >>> Dive two days in the cenotes and one on the reef (I hear I should go near Puerto Aventuras) >>> Dive two days on the reef and one in a cenote Are the caverns worth two days?

drsteve 6 Posted April 29, 2008 Should I: >>> Dive two days in the cenotes and one on the reef (I hear I should go near Puerto Aventuras) >>> Dive two days on the reef and one in a cenote Are the caverns worth two days? It depends on what kind of diving you want. We dove 4 days in Cozumel and one in Dos Ojos. The Cenotes have very little life in them. I was a little surprised that there were small fish in Dos Ojos. If you want to see pretty fish, dive the reefs. If you want to see interesting topography dive the Cenotes. One nice thing about our schedule was that we dove the Cenote on our last dive day. The advantage is that it was shallow and our gear was thoroughly "rinsed" for the return trip. Share this post Link to post Share on other sites

I'm inclined to think as interesting as they may be, the cenotes are a one day thing. One nice thing about our schedule was that we dove the Cenote on our last dive day. The advantage is that it was shallow and our gear was thoroughly "rinsed" for the return trip. Makes double sense!! Share this post Link to post Share on other sites

The cavern dive at Dos Ojos is amazing, we usually take that route on our way into the cave. Once you are past the stops signs, cave diving begins and it's all about scale and structure. I bought a Ikelite 225w strobe and slave sensor for this years' trip, I hope to get better pictures. Share this post Link to post Share on other sites
azcaddman 0 Posted May 13, 2008 http://www.ikelite.com/web_two/uarmatray.html - whichever size matches your strobe arms... these are your friends for cave photos. Mount one to the lower set of tank bands (works best if the bands are assembled w/threaded rod, so you have a 'stub' on the back side to attach the 9577.1 to) then attach your strobe arm to it (6-8" arms are good), and mount your strobe to the arm. If the strobe is pointing down, it's really streamlined, and nothing sticks up higher than the tanks themselves, restrictions are not a problem. When you get to where you want to take the photo, flip up the strobe, point where you want it, and shoot away. (3 foot extensions for strobe cord cables are a good idea also, allowing the diver to handhold the slave sensor). don't forget to turn the modeling light off when you're done though, anybody behind the diver with a tank mounted strobe will really appreciate not having to look at that light for the rest of the dive.

I was planning on having the diver hand hold the strobe and pointing it in the right direction or I was going to mount the strobe flat along one of the tanks with an argon strap. I never thought about mounting a ball and arm so that I could point it up and then back down for the tighter section. I'm just unclear how I would mount it. Are you screwing this ball joint into the portion of the extended screw on the tank band? I did buy the 3' extension cord based on your recommendation.

azcaddman 0 Posted May 15, 2008 ok here you go. -tanks are LP 85's, arm lenth is 6" (in between the balls) from above profile attachment closeup if the stub is too long, you could use a thumbwheel on both sides of the adapter, to stand it away from the tanks a bit. (i use Deep sea thumbwheels for this, works great) This shows the 2 ways I've attached them.. top has the advantage of a little shorter, so no gap between strobe & bottom of tanks (not a big deal either way), and it can be eaisly removed/attached once you're in the water. the lower setup has the added flexability of the 2nd ball, making it easier to rotate the strobe to fine tune what it's pointed at. I turn the modeling light on, so the model can see that the strobe is pointed at what I want it at (if it's to the side - this makes it easier for them to know if they're in position or not - for that type of shot. here's an exploded veiw of the components for each - I like the 1.25" ball arms, better grip for the heavy strobes (and they're what i've had for years, since before the 1" ones came out) this one illustrates pointing the strobe at 45° or so to the diver, you're not limited to straight behind etc. when stowed, we coil the sync cord/slave strobe, and place in the model's pocket so it's out of the way, take it out to shoot photos, then re-stow it. just remember to take the strobes off while you're still in the water... models HATE standing around waiting for you to do it on land, before they can set the tanks down on a bench/tailgate etc Art Share this post Link to post Share on other sites

drsteve 6 Posted May 15, 2008 I really like the idea of "hiding" the slave strobe on the model. I hadn't thought of that. You learn something every day. Share this post Link to post Share on other sites

diverdoug1 56 Posted August 6, 2008 I too am starting to explore cavern (not cave certified yet...) photography and have found little info. I am by no means an expert and have tried very little but here's what i've learned: - the wider the better, I use my 10.5mm fisheye. - try and have a diver model for you, it adds loads of context - avoid even front lighting, unless it accents some back or side lighting or is lighting the diver. Formations and walls look far better with harsh shadows, gives them depth. I find 2x 11" arms gets 1 strobe far enough out - use 1 strobe on the camera and 1 or 2 slaved either on a small plastic tripod (i have a Velbon) or in a diver's hand for side or back lighting. It also extends the reach of your lighting if the diver points the strobe away from you. - start with cave entrances, they're easier I only have 1 pic on hand to post, and it shows none of the lighting techniques as my 2 slaves malfunctioned this dive. Oh well. Have fun and be safe. Cheers, Chris Edit: This pic was taken at ISO 200, f/2.8 & 1/40th sec. I'd shoot wide open (f/2.8) and keep ISO low otherwise noise will appear in the darker parts of the pics. The only difference shutter speed makes when shooting away from the cave entrance is to determine how bright the diver's dive light shows up - and yours too, so beware. Another tip for cavern shots is using a small tripod set-up, and natural light, makes for some dramatic shots (especialy in grey-scale). Share this post Link to post Share on other sites
certainlyscuba 0 Posted August 16, 2008 ok here you go. Art Thank you so much for the detailed pictures. I have been using a similar technique (affectionately referring to it as the "butt strobe") without the arm and bracket, but was having issues with the strobe's ending position when fired, due to it sliding out of position with just a bolt snap connection. The arm is a great idea!! Goes down as one of those "why didn't I think of that!" moments. Amanda Share this post Link to post Share on other sites
