Which do you prefer?   The 2nd shot is with my iPhone set to the default Photo Mode.  For the 3rd shot, I set my iPhone to Portrait Mode by clicking on Portrait, which you will find to the right of Photo.

The difference is how the background appears.  In the 2nd shot, everything is sharp and in the 3rd, the background is a little blurred, which makes the sign stand out more.

3rd and Final Shot

I went for my morning walk on the boardwalk when I saw this girl coming towards me, carrying her surfboard on her head.

Most of the surfers I see are male and they carry their board under their arm.  So this was different.

I waited until she turned right, on this path to the ocean, so that I would be behind her.  

As you can see from my other two shots, it's much more impactful when she is in the middle of the path, rather than up against the side railing, especially  because this is a silhouette picture.

The other correction I made to my first image is to zoom in with my iPhone.  I would have had to run to get in position, and that would have looked ridiculous!!
