I am new underwater user of the A-80 with housing. I have read through the boards here and there is a lot of helpful stuff that has been posted-- thank you. I went for a dive and pictures cam back very green-- I think I need to adjust manually white balance, but how do you do that, take a piece of paper down? Thoughts or help would be great. FYI, diving in the Northeast right now.

I'm also from Boston..where in Boston are u? if you don't mind. I have the canon A70 and i just bought a housing for it...used in the Keys and it worked pretty good..didn't use it much since i got lost out at sea during strong currents and rough sea. Though if you have a white writing slate you could use that to set the WB. Other people on here will tell you better what to do.
I have the A70 and was just wondering the same thing. My pics are green in fresh water and blue in ocean water. Hopefully someone here that know how to do it will help us.
I did notice that my pics looked really cool when I printed them in black and white.

A white slate or a piece of a white detergent jug cut to size, use your imagination here, needs to be white and portable. I also have the A70 so here are the directions for setting it on that model.
Press the Func. button
Now scroll down one to the white balance menu.
Now scroll all the way over to the last icon and Custom will appear.
The LCD will say SETEvaluate White Bal.
All you need to do know is put the slate (some white object) in front of the camera and press the SET button. There will be a short pause then the camera will snap off a shot and set the white balance.
Now press Func. again to exit the menu and begin to take photos. Remember, this needs to be done at the depth the photos are to be taken at (when no strobe is used).

I'm using the A70 and find the manual white balance a bit awkward to use. For me, the simplest solution is to set the white balance to "cloudy" and do the adjustments in Photoshop.
Here in Southern Cal. it seems that I have to keep resetting the manual balance every few minutes as changes in depth/viz have a big impact on the amount of available light. (Plus, holding the slate and camera while hitting the "set" button really requires 3 hands.) Also, if you are on manual WB, you'll have to reset the WB when shooting in a shadowy crevice or when you need a flash

All good ideas. My pics came out very green-- and I did try and shoot on the cloudy setting. Someone else (scubaran)on the board recommended the following link from Canon, which I read: http://www.canon.co.jp/Imaging/uwphoto/index-e.html
I think the best thing to do is keep experimenting and try using the manual white balance stuff-- but it is a pain. I also don't want to have to go fix all the shots in Photoshop....doesn't seem right+it's a hell of a lot of work.

jpslim, I use the wrist slate technique for setting white balance, have used it in the lakes up here and down in the bahamas and found it works quite nicely for someone just starting out (I have the a70 and housing). When I was on blackbeards, I found I didn't have to play around with resetting the white balance too much because the ambient lighting was great... Echoing Jason B, visibility and lighting definately will affect how large your P-Factor (Photoshop-ing Factor) is afterwards.
Geez. This post is a year old. Sorry. I wasn't looking at the date!

I also use the slate technique with my a70. It works fine but yes you need to set the wb pretty often. If you decent for 5 metres light sure changes but as canon has made it so easy to set it ain't that much of a problem. Just don't use auto mode and if you are about to use internal strobe remember to set the wb with strobe on or just set the wb on auto. Otherwise u get nice red picture.

I have a white dive slate attached to my wrist (actually its tied to my dive light, which I attach to my left wrist), that I use to constantly adjust the manual white balance, with practise its easy to hold the slate with one hand, and press the camera buttons with the other, in a few seconds.
here are some photos taken the other day with manual white balance:

I did not photoshop process the photos afterwards, they are straight from the camera. make sure you turn the flash off before you manual white balance. I am using a canon a70.
