Which URPRO filter in So Cal?

[ChrisA]

I would post this in the photography forum except that I'm looking for aswers specific to the local waters.

For use with a video camera without lights, which of the URPRO filters do people like best for use in (1) catalina's clear water and (2) for beach diving in So Cal. Is it the URPRO CY or the URPRO GR for So Cal? The local, near shore water is looking a bit green llately I'm wondering if the GR filters would be better?

Hi Chris,
Are you shooting digital? If so, then I recommend using adobe premiere or simiilar to run the filters as a post process. There are a few reasons for this: first you can always choose the right filter after the event, and 20/20 hindsight is a wonderful thing to have. second, the addition of a filter reduces the amount of light you capture and that is always a bad thing (the sensors on those cameras are small enough as it is), third, a filter over the lens affects all three colour channels whereas you can probably do the best job by modifying only the green (for nearshore) and by working with luma-> red boost for clear water.

We had a thread on color correction in the U/W videography section a while back, where there was a good discussion on which settings to use, and there are masses of resources on the web on the topic.

Hope this helps.

Yes, digial but it's Video. I have a miniDV camera in a housing. You can do color correction in video post processing but it's not nearly as easy as with still photography

You are right about filter cutting down light. Something that is a goodthing. For example if the blue channel saturates and burns out before the red gets to register. With a filter the automatic exposure system has a chance of gettig all three channels within range.

So I'm looking to get the coor "close" with a combination of filter and white balance control. Later in post production I'll do the final tweeks on just the just that did not get cut out
