Auto white balance.

[wooflad]

Hi there, just a quick question,
When setting the white balance underwater manually, do you use a grey card or pure white. Ive heard mention you can use either, its for a compact fuji f31.
Any help greatfully recieved.

Cheers

As recommended by someone on here (I forget who but thanks a lot) I point the camera at sky in a vague sort of way and it seems to work.

I have quite a bit of fiddling with manual white balance over the past few monthe including video. A white card gives the best results, however can be a pain to carry. I am in the process of trying to find a paint to paint a fin white, looks daft but saves a load of hassle, plus its for a video housing it is a bit more difficult to use a card/sheet. Setting the manual white balance gives better results than any filters etc even at places like Capers the results can be obvious..



and without white balance ,go a few minutes in when its a little deeper

White wrist slate does the job nicely.

In answer to the original question, white card or grey card are identical for this purpose - the point is they're both neutral colour.

Just a short note to say thenks for the replies. Think i will give the white wrist slate a go cos i already have one of them.

i use an A4 slate.
i cut it in two, made cord loops for hinges so it fits in my pocket.

i found i get more accurate wb cal, being able to hold the slate at full arms length +still filling the frame.

if there is a large patch of sand, ive used the sand to wb cal before +got good results.

i think the grey slates, are for exposure compensation.
with a range of grey slates that will be say 1.0-1.6? equivelent when cal'd on.

I have a fuji F31fd - if diving in the red sea what white balance setting do i set it on or does it depend upon the conditions? never used white balance just etnd to use underwater setting but results can be dissapointing.

thanks

if you can calibrate the wb, i'd do that.

i have always found cal, better than auto.
+i find auto wb, slows down the camera shutter response.
causing me to loose many a good shot, due to combined digi lag, while its doing its thinking

then i'd use auto iso +other settings.
check each pict. i find the exposure can look better reduced, on occasions.
