Setting custom white balance in 60D
I'm using a 60D and trying to figure out the quickest way to set a custom white balance (especially in video mode, where post-capture correction is difficult).
The way I understand it now, assuming I was previously in Auto WB, I need to take a reference photo of something white to use a a base image, select Custom White Balance from the menu, select the image I just captured, then go back to the menu, select White balance, and then select Custom from the While balance options.
That seems like a fair number of steps, especially compared to the something like the S95 that lets you do the metering right within the White balance menu selection without taking a reference photo. Am I missing a shortcut for this?
