i missed a small group photo because of my noob skills.
was at a chalet, and taking pictures outside the chalet during the night (so it was low-light?) then wanted to take a group picture but my d3100 didn't want to focus, so i tried to get it in focus by moving the camera around, but it doesn't work.
and by that time some of the group people gave sneering remarks and the group was dismissed.
that's how i missed taking a group photo. should have turned it directly to auto mode and take the picture.
after that i was quite sad for a moment. need to up my skills by a lot.
