Ive been looking on the internet to try an answer my question but cannot seem to find it. Under TV and AV mode on my eos400d if i press the AV+/- button the light meter highlights and i can change it with the wheel, what is this doing? i understand the basics of how TV mode is shutter priority and the aperture automatically compensates the exposure when the user changes the shutter, and likewise with AV mode.
