Thank you .. what filters should I bring? I assume you mean filters/gels/diffusers on the strobes themselves, not at the camera.
For fluorescence photography, you need a filter on the light source to limit the output to the excitation wavelength, and you also need a second filter on the lens to remove the excitation wavelength, and only allow the emitted light. You are trying to photograph the light that has been re-emitted by the fluorescent organism. If you allowed the excitation light to reach the camera, it would over power the weaker fluorescence signal that are being emitted by the various organisms. So, as Bill says, you need filters at both the light source and the camera, albeit different wavelength filters at each spot. I hope that makes sense.
Thanks very much for all the good advice. I rarely use dissolves, and mostly just use straight cuts, but didn't really have any good reason for that - it just felt right. I'll look into that book, thanks!
Timccr - could you elaborate on your advice? I don't quite understand what you're saying, and would like to improve my own editing abilities. Could you explain in more detail your "editing philosophy", if you will? Thanks.
I am currently reviewing several underwater photography textbooks that have been released in the past year or so, and it is interesting to note that they advocate shooting at base ISO whenever possible. In fact one suggests stopping down is preferable to moving off 100 ISO!
They are written by folks that did a lot of film shooting.
That's an interesting observation - and probably a very important one. My main background is in film photography, and I am still learning how different the digital world is. A lot of the skills that I had learned just aren't needed or are wrong, so digital can be a challenge still. But, that's also what makes it interesting, and why I appreciate all the great advice here on Wetpixel.
I'm nowhere to close to being at the level that you folks are discussing, and really appreciate that you give help and advice to those of us who are less talented. I simply shoot to be able to document what I see, and to share it with the folks that I have been traveling with (as well as anyone else who would like to see my work). It is just about the pleasure of seeing a different world.
Nice work, as usual. I liked the "tilted font" effect that you got on your name in the title sequence at the beginning. I was also very impressed with the water clarity, and how much of the plane was still intact after all this time.
When I'm shooting video, I always carry my two video lights. Macro shots, at least, can almost always be improved with additional light. Shallow water with bright sunlight being the only real exception to that rule. If I have them and don't need them, that's better than needing them and not having them available.
