TRV-900 and Amphibico Navigator Can't Post

I just got back from a great trip to Komodo National Park. I however, had difficulty white balancing beneath 15 ft. It worked fine at 15ft but go to 20ft and it just wouldn't set. It would blink as if it was trying but seemed unable to process the light level. Any ideas?
Many thanks,
Jason

Hi Jason,
Did you see any dragons down there?
I have also encountered the white balance "non-stick" on occasion with the PD150. Scuba Zoo (video training) people have told me it is fairly normal to run into an instance where it is difficult to get the white balance to "stick". Somtimes it requires that you keep trying severals times and you may have better luck white balancing onto some corals or something with a lot of contrast. In my experience I just keep doing it until it sticks and I like the result. If I dont like the color, I aim it onto something else until I like what I get. It is an art form. Using a white slate often gives me too much red or other weird coloration but other times it works nicely. I have always used a red filter and can usually get it to white balance and stick on the surface. Are you using a red UR Pro filter?

Hey Bob,
Thanks for the reply. Yes, I saw lot's of dragons. I was on the Komodo Dancer for 11 days. The diving was excellent. It seemed that at depth the camera just couldn't adapt to white balancing. Yes, I'm using a red filter. I did primarily use a white board but didn't try and utilize coral or sand extensively. Just tried it a couple of times and it wouldn't work. I just ended up setting the white balance at 15ft and then shooting the entire dive at those settings, which at 20 ft wasn't too bad but at 60 ft pretty much made little difference at all. I'm going to stop into a local video store and see if they have any ideas. Thanks for the reply. Jason

Try using a higher contrast scene to white balance+ [In reply to] Can't Post

The red filters from URPro are daylight balanced to 60ft so you could put it in
daylight mode if you have trouble finding higher contrast subjects.

Use daylight setting [In reply to] Can't Post

Most camcorders aren't capable of white balancing correctly with filters as heavy as the UR-Pro. Use daylight setting instead and filter only when the conditions require (I.E. at depth).

Re: TRV-900 and Amphibico Navigator [In reply to] Can't Post

I have had the same problem from time to time with my VX2000/Amphibico. When this happens I point the camera to the surface and do a white balance, I then retry using my normal object for white balancing. It works for me !
BTW I use one of my fins either painted white or with white gaffa tape on it to white balance.
Hope this helps,
Rob.
