In Topic: Internal dome reflections.

11 August 2015 - 07:54 AM

The problem with the Sigma 15 mm FE is the front part (around the glass) and not the outside part of the lens. Since that area it's not mat, when we try to do some backline shoots with the sun in the picture one can see the parallel lines in the reflection inside the dome (I use the Subal DP-FE).

I'm surprised that not every people that use this lens doesn't have the same problem. Or maybe they still not noted it...


Although in photos its possible to use PS or LR to fix it, a major problem is when shooting video. It will ruin completely the footage :-(


Until now I wasn't able to find a good solution. I've tried to glue some mat tissue but it came loose. Permanent ink (like Edding 3000) is not mat enough. And since the lens is metal painted black, its not possible to sand paper that area either.


Anyone have another sugestion?



In Topic: Fluid video tripod head

20 November 2014 - 04:16 PM

Hi all, thanks for the answers.


I do take my video job seriously. For years I've used regular topside tripods (Gitzo) and ball heads underwater. Caring them underwater its not a problem (although I admit that some times a lift bag will be very handy..)

But now, after 15 years of use uw, my Gitzo head (ball head) needs to be replaced. I have disassembled it many times to clean it, and thats why I wonder if that will be possible with a fluid video head and, if not, how long will it last.


Many times I've used them in situations where a small / dedicated uw tripod will not work due to its limited size/high. In some very limited situations I've used a monopod, but most of the time, I need a tripod so a head is a must.

TLC tilt/shift head looks good but I'm not sure about the smoothness of the movement. And i don't need the legs. But, anyway, I will look more carefully at this option, especially because of it's corruption free constrution.

ULCS looks too small for the kind of gear I need to put on it (DSLR housing + external monitor + arms and two lights).

Yes, how is this project? I'm very curious too...

In Topic: Subal D7000 Port Boyancy

Are you sure?!?!?!?!


I'm not sure if you are making a statment or posing a question, thought.

I use Subal equipment for a long time and (as in any other brand) the underwater weight of the 8" dome vs the 60mm flat port are quite different...



In Topic: Thoughts on external vs Internal filter ?

25 September 2014 - 06:24 AM

Red filter can ne benefical to both photo and video in conjunction with custom WB to mantain blue water color and prevent it to become grey/dull.

If you need to use flash/video lights for the foreground (while using the filter) you need to put a cyan filter over the light so subjects will not become redish.
