Hi all,

Maybe a stupid question but how do you correct the white balance
when there is nothing real white in the picture...?

Thx,

Daniel Alaerts

DLKAPA,

I don't have one yet...
But sometimes I have to 'seach' a while for something 'real white' so
my question was only if I have sutch case...

Thx,

Daniel

Does your whites come out blue i had this problem on auto white balance and the camera on auto always gave me a blue shade through out the picture for some reason .
Still to this day im puzzled why this happens.

Nope...
I shoot RAW for night shots so afterwards I can set the whitebalans
correct.

Daniel,

What's 'white' in the picture isn't so important, as how your camera 'sees' the picture. It's more a case of your camera reading the colour temperature of a scene correctly. Under certain conditions, it won't do this, which is another reason RAW is a handy format to use, as you can just change it afterwards.

If you're talking about setting the white point in the levels function, you don't have to do that - instead you can adjust the white and black point by hand until you get something that resembles how things looked on the day.

Jumbo jim:

The blue colour cast you mentioned can be a pain. In my case, it's been because the camera has assumed the scene has a higher proportion of red in it than it actually has, or a lower colour temperature, and has corrected by adding that blue, which has knackered the picture  Sad

Cracking article on the theory here:

It takes a big man to admit they are wrong, and I am not a big man.

I read the article the link provided but im still puzzled as to why the camera cant get the white balance correct.
When i shoot on a normal sunny day with white balance on auto i get a blue shade all over my picture with my d70 when i use my Olympus c740 i don't have the problem .
I can fix the problem in the editing but then it throws the colors out then i have to try to get them corrected.
Anyways
Cheers on providing the link
