I have a Canon 60d and shoot in manual with just the center focus point and recompose after gaining focus. I generally leave the ISO on auto and compensate if it gets to high by changing the shutter or aperture myself. I ran into metering issues when I was taking pictures of my dogs (they're black). I would point the center focus point at them, half press the shutter release, and the ISO would jump into the stratosphere. I'd then move the point away from them to something lighter while still holding the shutter half way and the ISO would drop down again. So I did research into metering modes. It seems my camera's don't work though. Even though my camera is on evaluative metering, it's always adjusting the ISO only to what's in that center focus point! I've taken pictures changing between spot metering and evaluative, the two extremes, and nothing changes. Is it because I've disabled the other focus points? Thank you!
