Assuming that manufacturers come up with housings that allow full use of the 5DMkII's capabilities underwater, how would you think one would address the need/desire to use a red filter for video mode, but be able to switch to still mode and get rid of the red filter...during the same dive? It would be easy enough to put a red filter on a given lens, but then you'd be stuck shooting video the entire dive. Could a custom white balance be created to mimic the effects of a red filter for part-time/sporadic video use during dives?
Ideas/suggestions?
Flip filters are available for most video housings. I wonder if the still housing companies will include them in the 5DII housings...

What about a product that allows you to white-balance? It could even be something built into the port! But maybe that would be too stupid.
I kid, I kid...
Carry on.

I thought of that, but unlike a video housing, where the camera/lens are only one size, so a flip filter just inside the port glass works great (e.g., Light & Motion housings), here you need something that could work with macro ports, dome ports, and all different lengths of lenses/ports. I don't see how anything inside the housing can do that.
A red "wet filter" that slaps on the end of a flat port would work for lenses that go in a flat/macro port, but what about wide angle (where you would likely use video the most)? Seems like a dilemma to me!
Bruce, you'd first have to look at the 5D2 and how it handles WB... it's AWB. So having a filter will just take 2 stops of light to balance out the blue/greens. To me it's not worth the loss of light, considering how the camera works. Shooting macro you should have lights anyhow. For WA, nothing short of 2 200W HMI will illuminate subjects just 5 ft away, so to me that's a wash and I'd shoot natural light anyways. The implementation of video on the 5D2 also limits latitude due to how it's processed (clipping highlights). I think most of the work on the 5D2 will be done in post, to deal with the limitations of the camera video.
As an aside, I did try using Magic Filters with AWB in my 1Ds2 and 1D2 and it did a decent good getting the colors close about 60-70% of the time. All in natural light, no strobes.
