Ok, I know there is a simple reason for this but my frustrated mind won't let me figure it out...went to a family wedding last Sat. and thought here's a good opportunity for me to practice a little with inside and flash shooting, which is the worst of my diminutive skills. I got a few nice shots from my seat, and could readily see how my new 580EXII flash
helped make a better photo. What kept getting me frustrated is I couldn't get the shutter speed to cooperate when the wedding party members were walking towards (or away from) me down the aisle. I was shooting mostly in AV mode, tried various ISOs and apertures but kept missing focused shots because they were too blurry from slow shutter speed (I say slow, it would be say 1/60 when I wanted much faster). I understand how the photographic triangle (aperture, shutter speed, ISO) affect each other---no I guess I should say I understand that they DO affect each other, but it seems to elude me while shooting what needs to be changed to get what I want. Maybe it was the AF mode I was in? Maybe I was in AI Focus and it needed to be AI Servo? I know it's hard to address this without photos to look at, but my laptop with all the photos is being worked on right now, so I'm trying to write all this from memory. I was really trying to concentrate on using my AF points bc getting eyes in focus is something I am working on, and unless I totally misunderstand the AF modes (entirely possible!) AI Servo will change the focus points as the subject moves, so I assume I had it in AI Focus...I was trying various apertures, I think mostly around 5.6-9...also tried various ISOs 400 mostly I think....I can hopefully answer any questions that would help narrow this down when I get my laptop back, but any educated guesses out there?
