New user reporting. 650D with 18-135mm! Contemplating to get Sigma 30mm f1.4. Everything feels very foreign because I've been shooting in auto on digital cameras for the longest time ever. Just a question about the camera. I was just taking a few photos in my room in Av mode with evaluative metering, automatic AF point selection, and most photos are actually overexposed (half of my blinds were opened so the room was unevenly lit by the sunlight) I had to adjust exposure compensation to -2/3 stops before it was properly exposed. But when I shoot manual mode, the exposure compensation will be moving as I point the camera at different spots and manipulate the ISO, aperture and shutter speed so that I know how to get a proper exposure. Any way to make it such that I can get the same results with Av mode without messing with exposure compensation? I was using evaluative metering and automatic AF selection while in manual mode too.
All along, I thought the only two variables to play around with in Av mode are aperture and ISO. But if most of my photos are overexposed at 0 Ev, then is there something wrong with my camera? It wouldn't make sense if my photos are all exposed properly only at -1/3 Ev and below us it?
I apologize if this is too newbie of a question. Just trying to slowly learn from the community here
