I use Aperture Priority most of the time. If I'm not using Av, I'm using Manual.
From looking at some of the older film cameras like the shutter priority came before aperture priority. The Canon AE1 came out before the AE1 Program right? I know a lot of people use it, but I don't understand why.
To me, the choice between f/4 & 1/125 or f/2.8 and 1/250 comes down to f/4 or f/2.8.
Even when shooting action, I use Av. I set it to 2.8 and adjust the ISO until I know the shutter speed will stay at or over 1/1000. Is this backwards? Say I use Tv and set it to 1/1000 and ISO 800 is giving me f/2.8 when I point it at the field. If the sun creeps down, won't I get underexposed shots? I'd rather shoot at 1/500 than have the shot a stop under. If the sun creeps out, it might go to f/4 and I would have rather had f/2.8 and 1/2000 for subject isolation.
If I'm shooting a wedding and I want to drag the shutter, I'm probably in manual mode.
Who shoots Tv? Please explain to me why I should reconsider. I feel like I am not taking advantage of a resource my camera is offering me.
