Hey guys/gals! I've got a new Xsi, and I have a question regarding the automatic exposure compensation.
I took two pictures of the same stationary object, in the same lighting. In "P" mode, the camera set my shutter to 1/60 and the apeture to f/4. I immeadiately took the second pic in "Av" mode and set a matching apeture of f/4. But this time the camera set the shutter to 0.3 seconds. All other settings remained the same: ISO, Metering Mode, WB, etc.
With the exposure level the same, shouldn't the shutter speeds be identical in both situations? What am I missing?
Please be gentle.
