Do you wait for the best facial expression?

I try and pose the people that I'm taking the pictures of. It doesn't always turn out for the best though. Sometimes its best to keep it candid. I do try and wait for the best facial expressions though. Like was already said in here, I take a bunch of pictures and then delete the ones that I don't like. I like my options to choose from.

maybe. If I take some useful photos,I'll. and If I take some life style photos,I don't care about this. Causal face expression is OK. or Only body language can show the emotion of the people who in photo.

I used to take pictures for a living and my technique is not to wait but to just shoot. I get some surprisingly good results from this. Cheers!!!

When I take photos I just keep on taking and taking and then deleting the not so nice ones. I don't wait for the best shot because I can't tell if the person I am taking picture of will be satisfied. And besides it is nicer to take pictures the natural way and that is by smiling the way you feel comfortable with. My husband and I loves pictures so much that we always take pictures of all the places we're going to and the foods we are eating. Others may find it unusual but we kept pictures of food and then we compile it here in our computer.
