HOW TO ACTIVATE IT?
go to -1.0(in my phone I put CWB on that EV position)
zoom once to a white surface which is gonna fill the all screen
after You notice that CWB is activated(shouldn't take long according to me 2-3 seconds)zoom again to lock it
and then You are ready to take the photo
but how can this decide " best WB to use at the moment when YOU ARE taking the photo." if you are using a simple white paper every time to calibrate it .. whats the difference ?.. it may as well be activated only once and find a way to lock it forever... ( this may be a lame question ./.. but i can't understand  )

well i see your point ... hmmm, maybe i kind of agree? :S what do u guys have to say ? if it is white, why can't we lock for all pictures?
or when u say: point to white u mean, point to a "all white card in the place you are" so...you'll be using whites with the tones and temperature regarding the place you are at the moment? or am i talking rubish?

I don't know if it can be locked forever.Only Raider knows that.But I think that's a very very bad idea.sometimes CWB gives really warm colors that adleast I don't like(no offense raider). |

I don't quite get You.But Raider said it's not nessaserally have to be to WHITE card it can be to yellow and grey card aswell.he ssaid he didn't tested CWB much.I think when he will he'll give us more accurate infos in which coonditions to use which colored cards. |

i think we "have" to use the white paper, so the algorithm can read clearly (entire white paper) the whites proportional to the light your current scenario is using and then generates the best white conditions...
is this right? |

cannot be done like that...the trick is to 'calibrate' using a white paper or a white surface under the current light condition. Actually, CWB is not useful for amature photogrphers and K800 cam ...Saturation, manual EV and AE lock are more to the point...i mean for 'point and shoot' K800 oweners |

got to say, i tried in 3 different scenarios...and nop..i don't like it. pictures are too too cold.
i used SEM and CWB and SEM alone . and i prefer SEM in all 3 conditions and scenarios instead of SEM + CWB. |

The second photo is with CWB and I'm very pleased of the colors and it looks just like the real mushroom:
I still wait for those opinions.and advices
i was talking about this.CWB makes photos look so GOOD and with real color:
Raider thank You for Your driver.
In the first photo the "mushroom" is too warm(in my defense it was my first CWB shot)in mean time during the 1 and 2 photo i started getting the hang of that.
on the second picture with the same settings and with the same white card.
I think the second photo is improoved a lot |

congratulations for Spain! impressive massive domination
just point the screen to all white areas i want to include in picture, without pressing anything? then use custom and lock ?and take the picture?
1. put white card (paper, plastic, etc.) in front of your camera
2. start Custom WB (+1 on CWB function)
3. wait some seconds until color isn't "whitened" and then lock WB (+2)
...
4. after shots you can unlock WB (+0) if you want or just restart camera for auto WB
the best situation: if light falling on card is same as light falling on object which you wan't to photograph
which are the best settings 4 indoor pics?
i use twilight portrait+iso 100+incandescent and SEM on..and i get crappy pics
what type of indoors? daylight or bulb? and what do you mean by "crappy"? show photo
besides, you don't have to set ISO100 because SEM/EM is forcing ISO100, always
is it possible to combine EM and SEM with CWB ?
sure
if it is white, why can't we lock for all pictures?
we cannot because white color (result of CWB) is reaction for light "at the moment", I mean for current light conditions. light can be warm or cold. white color is just a result of added yellow to blue (cold light) and blue to yellow (warm). we only see white color but it's not "point 0", it's always balance of yellow and blue. of course there's also cyan-red balance in all CWB calculations
Raider said it's not nessaserally have to be to WHITE card it can be to yellow and grey card aswell
that's true. this only depends on result which you need. use yellow card to make CWB result cold (blue), use blue card to make CWB result warm (yellow) etc. sometimes result of CWB is not good but I'm quite sure that's because of very amateur method (paper, shadow on paper, etc.), nothing like this: http://tinyurl.com/54nvo5

Raider I have a question.is there a way to "warm" up a bit a cold photo?
here is an example:
We have a warm photo and what if we use exposure to make the photo brighter a bit.the same question goes for warm photos.
THANK YOU
