I lightened this picture up a bit because it was very dark.  

For this picture, I cropped it so that all of the people fit tightly in the frame.

This picture was slightly crooked, so I straightened it and cropped it so that the two people fit tightly in the frame.

This picture had something else to the left of these ladies, but they were the most interesting part of the picture so I just left them in.

This picture was also crooked, so I straightened it up.  Also, I cropped it down to just these two girls.
