Setting white balance
I'm a little confused about this. I'm going to London and visiting Tower of London and other landmarks, etc. Can I set the white balance outside before I go into one of these places to take photos or would that be all wrong because the lighting is different inside? Would the WB have to be set inside to get accurate photos? Same goes for ice hockey games. Plan on using RAW if I can and have a Canon 20D...

Yes & No. You cannot preset the actual WB based on the light elsewhere but you can use one of the presets such as incandescent or flourescent (or flash) as appropriate. To get the light completely right you would need to pre-set the WB base on the actual light. But that might vary enormously from one room to another (depending on the balance of incandescent light, daylight and flourescent light).

WB have to be set inside to get accurate photos? Same goes for icehockey games. Plan on using RAW if I can and have a Canon 20D..

With RAW getting the WB right is less important as you can adjust it afterwards but it is always best to get it nearly right at the time otherwise you might blow a highlight in one or more of trhe channels that would not have been blown if WB was correct (or end up with no colour in one or more channels where it is blown)..

There's two reasons cameras have automatic white balance settings..

They make pictures look better..

They remove the need for beginners to worry about one more thing until they have time to settle down and learn more..

Brian,.

That's a contradiction..

Anyway, I tried it today. I used a white card outside and took some RAW images of trees/flowers and adjusted the sharpness/brightness a little with Canon software and they came out stunning! Thanks...

I have yet to see a DSLR that handles incandescent light well on Auto WB. It is a regular compliant of reviews on this site..

My common practice is to use Ato WB unless shooting incandescent. But then I shoot RAW anyway..

But the problem will still remain, when processing the RAW file, of determining what is the correct white balance..

Say you shoot a metal object. It will have bright highlights, dark shadows and widely varying tones in between. What will you use when processing the RAW file to set the correct balance? Is it made of copper or brass or iron? Unless the lighting is constant throughout the entire exhibition, the results will be purely arbitrary and based upon an imaginary concept of what the subject ought to look like..

On the other hand, setting a manual white balance using a reference white subject at each location where the lighting changes, will enable correct adjustments to be made later.Regards,Peter..
