How do you read a Histogram?

[Raymond Lin]

Since the LCD is small so its hard to tell if the shot is 100% exposed correctly and people use the histogram to check. The problem is I never used it, anyone wanna show me how to read it and what is a good curve and a bad curve?

When it says blow the highlights, that means over exposed right?

This generally means you are exposing for the brightest parts of your shot.

Spot metering on the 30D for the win

Meter on the bright part - ie wedding dress and shoot !
