1) If you’re taking photos in a studio, use a mannequin for light testing: Much easier than guesstimating!
2)Focussing is easier if you use a smaller aperture.
3)The settings in which you make pictures of people are important because they add to the viewer's understanding of your subject.

I choosed these two pictures because they both focus on one main thing.The background even though it has people in their .The people seem to been put their randomly because to me what i mostly focus on is the environment behind them.

I choosed these pictures because they are dark and focused on the girls.
It shows some kind of feeling it like gets your attention in the way they their face is postured or focused.
Like in the first picutre her face is really serious but focused on.

These pictures i choosed them because they are simple and plain just focused on the person and their background.It's just a simple picture that was taken.
