HuuUuullo!
I have questions
, but first here's my background:
I'm going diving in Cozumel (@ end of July), and I'll be taking a camera with me for the first time. I'm a student and I don't have any money, I'm actually already severely in debt.
That being said, here's my setup so far
Fuji e900 - Ikelite housing
(I'll try to purchase AD-Mount, and INON macro lenses)
(^^ I need to sell stuff to be able to buy these items)
.. and I'll make my own DIY tray and handle
I've spent the last 8 hours reading everything I could on the subject..
I can't afford a strobe right now and I've come to the conclusion that I don't want to buy a cheap one, I'd rather wait to be able to buy a good one (but, that wont be before my vacation).
If you throw into the equation that I'm an inexperience diver (just got certified), I'm not sure that I want to have to deal with the strobe anyway right now.. (I think I'll have my hands full with controlling my buoyancy) :11:
Anyway, I've seen good pictures made by people using dive-lights or even aiming lights (rather than strobes).. and that made me think about headlamps!
I use those regulary in any topside activity (climbing, mountaineering, kayak, camping etc)
I'm now looking at The Pelican 2680 (waterproof to 500', 33lumens, 5000lux) 60$
http://www.pelican.com/lights_detail_specs.php?recordID=2680
This headlamp is tiltable so I can point it down so NOT blind my buddy while looking at her. We wont be diving at night, the light would be basically only used for macro-photography, and since it would always be lighting what I'm looking at, it seems to me to be a nice no-hassle setup
BUT.. Since I never used a light underwater, I'm not sure if that little lamp will provide enough light to actually help at all!
I don't intend to dive on wrecks, at night or in cavern in the near future..
Would that light be a waste of money?! (I looked for others like it but only found nightrider's @ 200$+)
If you don't recommend that light, what kind of result I should expect while using 2x stacked Inon 165 macro lenses with only ambiant-light ?
I read that the DOF and focus distance is real-tricky with 2x stacked macro, is it also true if using only one macro lens!?
on another mather, if you were to stack a wide-angle or fisheye lens on top of the macro, what result would that give?! (I'm curious)
one last thing, concerning ISO.. I saw that a number of people here are shooting at very very small iso (like iso80 / iso100 etc). Since every time the iso is doubled, you double the "light-sensivity", why is nobody (without strobe) using higher iso in these low-light situations? (I know all about "noise" at higher iso, but between a "noisy" shot and no-shot at all, seems to me to be a no-brainer..) What am I missing?
Any help, recommandation or insight will be greatly appreciated!
thanks!
