In Topic: Color Correction with FCPX

Hi Thetrickster

 

Yes, there is a way to correct WB in FCPX. You can use a free plug in named RT Color Balance or you can do it without the plug in:

In Topic: Tokina 10-17 on FX

I have tried the 10-17 with a D800 at 17mm. I have a Subal D800 housing and discovered to my chagrin that the only way to use my old type 3 dome port was with a port extension. Without one the port doesn't fit on the housing. So I can't use a prime fisheye unless I buy a new port. ...

 

gecko1 :

Just send an e-mail to Subal because it's possible to change the back of the dome or buy a Subal adapter type3-type4. Everithyng have a solution :-)

 

Cheers,


In Topic: Testing lenses underwater.

13 January 2014 - 10:04 AM

The problem of too many lens/domes/strobes on the market will be a challenge to test everything. I've done my tests with my Subal gear and my lens in order to exclude /include some bad/good combinations and to have a good feel of distances/magnifications that each combo can deliver. I've used the test chart I've mentioned above.

 

I don't mind to where some thoughts and some personal conclusions if there are some more people that have done the same thing, so we can start some sort of database.

But of coarse that it will be just a starting point, because I believe that each photographer should do his own test with is own gear.


In Topic: DIY Underwater Tripod

03 January 2014 - 01:06 AM

Yes, I see your point of view. For years I also had used the weighted tripod version (legs filled with granulated lead) and no doubt it was stable but cumbersome to haul around, especially out of the water. It was a cheap supermarket tripod, and not very good.

 

After that I've bought a Gitzo one, and it stills work fine, after many, many years of underwater and on land use. It's not cheap but defenitively cheaper then a dedicated uw tripod and much more versatile, although not so 100% water-resistant, of coarse. And with this one just made a hole on top of each leg to let the water came in for added stability. Some times I've used a 2 or 3 Kg weight suspended under the central column (if there is some space between it and the bottom) or a 2 Kg neckless that I just put around the top part of the tripod legs (it's the same thing that free divers use around the neck in swimming pools to trim the body position), but not any more because I've found that I really don't need the added weight.

 

Above water the tripod weights around 4 Kg (with the head), underwater a little less, so it's stable. I tend to use it with the legs very spread apart for added stability if the surge is strong.

I have used several times without any weight added and with the camera rig with the floats on, without any problem. So when I find the opportunely to try it without any floats in the camera I expect that it becomes even more stable.

 

My only doubt is the use of the camera rig  by hand (in regular photo situations) with floats clipped to it, floating over around, that I suspect that I'll not like that much...
