<span style="font-size: 10pt; color: black; font-family: Arial;"]Everyone is correct. You may be fooled by the overall scene. If you can get a grey card and shoot with it filling the entire frame, the histogram should show a narrow curve in the middle of the histogram. <o></o>


<span style="font-size: 10pt; color: black; font-family: Arial;"]I did this with my XTi for flash exposure. I adjusted the flash exposure till I got it in the middle. I leave it set there all the time and get good results. Mine is about 2/3 stop under. If it were more than that I would send it in for calibration.<o></o>
