How to adjust the background blurness of the picture taken with F/2.8 lens.
i am using 50d with tamron 17-50 2.8.
I take picture of my son most the the time.
Is it correct technique to aim at the subject face (half press to focus), then move to the side
so that my son face is sharp & clear & backgound blur ?
What focusing point should i use ? there is 3 settings.
I also notice that my 50d always auto select f/2.8 unless i purposely change it.
