Thanks Stuart, that's a very good explanation, and much appreciated.

The shots of the saltwater croc were impressive.

marcw - thanks for the link to Pirhana manufacturing.  I contacted them, got an email back very, very quickly even though it was on the weekend.  I have purchased a bungee mount from them.  If the quality of the mount is as good as their customer service, I'll be very happy.

I agree, very impressive.




#371018 Underwater Colour Correction With The Sony AX100

Posted by SwiftFF5 on 02 March 2016 - 04:24 AM

Thanks Pete.  I probably won't get any time to play with it again until the weekend (or maybe later), but I'll post again after trying some of your ideas.  Thanks for the encouragement.




#368759 A different look at Octopuses

Posted by SwiftFF5 on 30 December 2015 - 04:12 AM

Wow, amazing work.  I really liked the transitions where the artwork morphed into the live animal, or vice versa.  I can't even imagine how you did that, but it is a very impressive technique.  I generally like your work, but this may be the my favorite of all of the pieces that you've posted here. 

 

Can you tell that I'm impressed? :notworthy:




#367900 Best photograph/er lists -What makes for a great image?

Posted by SwiftFF5 on 04 December 2015 - 04:27 AM

This is a very interesting question, and I doubt that you will get a consistent answer - but I am guessing that there will be lots of strong feelings.

 

I am not really sure where I stand on this question, but I will compare it to similar questions regarding music.  I'm of the opinion that most of the major awards (ie Grammies, etc.) are more about commercial success and "popularity" rather than inherent artistic worth.  It is, of course, much harder to define and quantify "inherent artistic worth" than it is to do so for number of albums sold, number of social media "likes", etc, which is a lot of why the situation is the way that it is.  I would submit that photography, especially underwater photography, is in a similar situation.

 

That's my opinion, anyway.  Now, I'll sit back and watch the fireworks...

As always, fantastic work.  Thanks for sharing.




#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.

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.
