Thanks for your replies!
Are you using lights at all?
If not, manual white balance with red filter.
No lights, so far I have done manual white-balance without filter, just wondering if its actually gonna bring anything as I find the colors are quite good as they are as long as the conditions are ok and the depth is shallower than 10-15m.
If you are using a 7D you really don't need to use filters. It works great white balancing off the palm of your hand or sand. It really is remarkable how well it white balances underwater without filters. I've got great rests down to 40m.
Hi Simon, did you try it with filters for comparison?
With the 7D, the white balance goes up to 14k and thus highly adjustable. That said. It's a pain to MWB on DSLRs so I set it to one setting (daylight) and deal in post.
If you do a search in the forum, you'll find many threads regarding wb. It's really down to personal preference on the look of the video. Shallow wide angle benefits from the filter.
The Magic filters are great because they are available for fisheye lenses, something URPRO and other makes don't have( that I knowof).
I guess the way to go would be with Magic filters, just wondering if it would be worth it. I am just starting out with video, so post-proccesing is all russian to me (I am slowly learning though)..
I understand the basics of WB, have been shooting stills for a while now, just don't understand why the filter+MWB is better than the MWB with no filter..?
