For less than ideal "metering" condition, I heard taking a meter reading off the blue sky or green grass/tree would give you a quick and easy exposure setting. I have Canon D30. Do you know how I can do this? If I press the shutter a half way down and move the camera to aim the target, I can lock in the aperture/exposure setting. There is also an exposure lock button as well. But, does it cause some problem for focusing, as you need to move the camera after catching the meter reading off blue sky or green grass?
