Minimalism is described as a form of photography that is distinguished by simplicity.  When taking your photo opt for minimal subjects and use the negative space to place the focus solely on the subject of your photograph.  Rely on a simplistic composition and empty space to create a minimalist photograph.  Eliminate as much of the clutter as you can from your photo.

In this photo I focused on the keys.  That and the latch on the box are the only subjects in this photo.  Without any additional clutter in the photo, your eye focuses solely on the keys.  With the latch and the keys being the focus of the photo, don't you feel like that box is completely secure?

Keep your photos simple.  Use negative space and a small number of objects to create your minimalist photos this week.
