#366764 4K Sony RX100 IV Underwater Green Island Taiwan

Posted by SwiftFF5 on 03 November 2015 - 06:23 AM

leo99 - I try to do manual WB underwater to get close, so that less correction is needed afterwards.  There is still some, but I'm not running running out of room to make those corrections.


I don't use a white card either - I just dive with white fins when I'm filming, and sometimes using light colored sand works even better than the white fins.  Just some thoughts.

#366601 Sunscreen

Posted by SwiftFF5 on 29 October 2015 - 03:33 AM

There is a recent article in the Archives of Environmental Contamination and Toxicology that is getting quite a bit of press.  This article suggests that a common ingredient in sunscreen is extremely toxic to corals and could be part of the cause of coral bleaching.  One phenomena that has been somewhat puzzling is why bleaching is more severe in area with heavy tourist traffic, and this might help explain that phenomena.  Here's a link to the original article:




I tried to attach the PDF, but the file was too large, sorry.  For more information, you can also do a Google search for "Oxybenzone", the ingredient that appears to be extremely toxic, even as low as parts per trillion.

I wish that we had nice clear freshwater like that.  I'm  jealous.

Great clip - well done, as usual.

#365321 Using a UV fill light added to strobes for stills (i-Torch Pro6+) (?)

Posted by SwiftFF5 on 17 September 2015 - 02:57 AM


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.

Impressive, thanks for sharing.

Wow, very cool.  I like that sort of surprise, too.

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.

Really good - and I agree with your choices.  It had to be done that way, very effective.

You might get more looks if you posted this in the "classifieds" section.  Just saying....

#362045 Hydroflex RAC at the Silfra Fissure

Posted by SwiftFF5 on 10 June 2015 - 03:52 AM

Ahhh, thanks.  That sounds like a good system to keep the shoot organized.


Since we dive tethered anyway (black water), we use the OTS hardwired systems, but they limit mobility and would probably not work well for your situation.

#361407 Expose to the right?

Posted by SwiftFF5 on 22 May 2015 - 04:02 AM

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. 

#361378 Why do you shoot underwater?

Posted by SwiftFF5 on 21 May 2015 - 03:16 AM

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 stuff, you've got some nice clips there.  I also enjoyed the music.  Its a bit different from what we normally hear, and quite enjoyable.
