In Topic: Camera insurance, any recommendations?

21 June 2015 - 07:33 PM

I use H2Oinsurance.com for my underwater gear. The parent company of H2O insurance.com is "Senn Dunn Marsh & Roland". The company partners with Divers Alert Network.


A number of other underwater photographers recommended this company. I've not had to file any claims yet.



In Topic: Wide Angle Question Tokina 10-17 vs. 11-16mm?

14 April 2015 - 07:03 PM

The Precision Dome is considerably smaller than the large 8" Ikelite dome. It is manufactured specifically for different lenses. For example, my Precision Dome for my Nikkor 10-24mm won't work with my Tokina 10-17mm. I know several underwater photographers who simply started with a macro set up rather than purchasing all of the necessary gear (lenses, ports, & extensions) to shoot macro and wide angle.

Well, not everyone favors the Tokina 10-17mm Fisheye. I've got one, but I like my Nikkor 10-24mm better with my Nikon D7100 rig. While the Tokina Fisheye undoubtedly has applications, I'm not a fan of the curvature one gets with it. Of course, tastes vary. 


While I've got the large 8" dome and appropriate extensions to use with both the 10-17 Fisheye and the 10-24, I use a Precision Dome with the 10-24.


Hope your macro is a Micro Nikkor 60mm 1:2.8G ED. It's a great lens.



In Topic: Dome reflection ?

01 January 2015 - 11:03 PM

It's a problem that occurs with acrylic dome ports when sunlight hits the port at a certain angle.


I've seen it when I'm shooting my fisheye zoom and point the camera up towards the surface and sunlight. I don't get it all the time, but sometimes it shows-up. Someone told me glass dome ports don't produce the same issue. The same source suggested the use of black gaffer's tape  on the reflected surfaces of the lens eliminate the problem.



In Topic: GoPro Hero 4 Silver, 2x 2500 lumen lights, filters, etc...stick to video or p...

I think you posted a similar question about lighting for video without the sample photos on another forum.


A couple of the photos you posted here illustrate shooting beyond the reach of your lights. Your filter will compensate to some extent, but you'll see better results if you get closer. Attempting to shoot subjects beyond the reach of lights is a common mistake; I still try to push beyond the limits in hopes of getting lucky more than I should.


Keep in mind that the GoPro shoots at a significant wide angle, and it doesn't focus on things that are closer than twelve inches unless you've got an accessory close-up lens installed. Stills are captured in jpeg format at 12 mg pixels which is on par with many point & shoot cameras. Many of us use systems that record in RAW at higher pixel counts. RAW allows for lots more editing


Your turtle photo captured good detail and its fin that's out of focus is simply closer to the camera than the lens can focus. If you haven't tried tweaking the sharpness with your photo editing software, you might give that a try.


GoPro's have come a long ways since the company produced and marketed its first model. Lots of folks have been producing some very good quality underwater images and video taken with their GoPro's. Like any piece of underwater photo/video gear, there's a learning curve that accompanies using it effectively. Invariably, when someone posts a really clear video shot with a GoPro, people always ask how the heck he/she did that?


I received a GoPro 4 for Christmas and played with it while diving in Kona last week. There's a lot I need to learn about it before I produce anything worth posting. I'll probably sign-up for a class. Part of the magic involves getting the settings on the camera configured correctly... it's not rocket science, but I need some help anyway.


Once you've got the settings configured, you need to get out and shoot pics and video to see what works.
