I have a canon 60D and was visiting with someone and they were trying to tell me to set the white balance you should take a picture of a white sheet of paper? I am confused. Is there a place I can find out more about this? Thanks

Fill the circle on your viewfinder with a neutral grey or white object. Then go into the menu for white balance and select that shot as the reference image. Then set your white balance setting to "custom". This is all spelled out in your camera's manual. Custom white balance is useful when none of the presets are quite right, such as under compact fluorescent lights which have a low Kelvin temperature and a strong green cast.

Custom white balance should also be done before shooting video in each new lighting conditions. Will save you a lot of heartache in post.

If you shoot RAW you can adjust white balance in post. One of the big advantages to RAW. Still useful to shoot a neutral target for later "eyedropper" correction, for non-critical stuff can usually eyeball it or use a neutral target in the shot (white shirt, paper, tablecloth, occasionally even teeth or whites of the eyes).

Not all whites are neutral. Get and use a neutral target, but realize it may not be the optimum WB, but gets a nice starting point.

I agree to all of the above, just realize: the times where to me setting a custom WB could be really helpful (or important) are typically indoors scenes with artificial light as the "main" light source and there is any doubt about the light "temperature".

In practice I use Auto White Balance most of the time, both for outdoor/daytime shooting and, when indoors, if I'm using flash. Note that I do shoot in Raw, and then I find that the camera does a pretty good job of handling the WB both for daylight and for flash. If I'm shooting indoors, I actually don't mind a bit of a "mix" between the flash and some ambient light.

However, I don't do studio shooting and don't have "stringent" requirements when it comes to my lighting and colors, so your mileage may vary!

Gray Card…White Paper. What’s best?

And just to muddy the waters a bit, remember that the "correct" WB isn't necessarily the "right" WB for a particular image? Would you want to neutralize the nice colors in a sunset? ;)

Use Auto WB, shoot in RAW. Get Lightroom (LR) & learn to use it, adjust every picture in LR.
Your photos will take on a whole new look.

The first couple of years of this hobby I shot in JPG. Finally someone convinced me to shoot in Raw. I never looked back.
Yes, the files are much bigger. I bought a 1TB external hard drive to store my pics, and I totally filled it up. Now I have a 3TB external.

Now the only time I ever shoot in JPG is if someone ask me to take a pic and they need it immediately.

I set to 5000K or do a custom WB, either way I shoot a neutral target. I never use AWB.

And given the data that the camera has to work with in that first image (if that is a large part of the whole image) AWB has actually done a very good job of balancing the colour in the image. Fill the image with a large area of any one colour and AWB will try to make it grey. That's all any automatic system can try to do, average the whole scene to match the three colour channels. I suppose that you could possibly add in some general pattern matching system that might say recognise what might be say sky in a landscape and add a little bias to the system to allow for the sky being blue.

Also I will add that the site has a limit of 1024 pixels on the long edge of any image embedded in a page to make the whole page easy to read. That big image really doesn't help if you are not reading on a large widescreen computer monitor.

It doesn't matter if the person posting the image can see it all on his/her computer. What matters is whether or not EVERYBODY ELSE on the forum can see the whole image on THEIR computers. Everyone should limit posted images to a maximum of 1024 pixels in either direction. That avoids problems with reading the text as well as seeing the images.
