Too many times our images are left wanting. Sometimes this has to do with including too much, sometimes it has to do with including too little. Sometimes, it has nothing to do not with what we include, but HOW and WHERE we include it.
In general, study the edge of your frame when you shoot and make sure there is nothing distracting that’s impeding upon either the subject or message (or both) of your image.
I have a rule I try and hold myself to: Make an image as interesting or engaging as possible with as little as possible.
There are, however, two caveats to this.
1. Know how your image will be used. Do you need to leave more negative space than you typically would for logos, copy or other extraneous additions to the image? You may want to shoot several versions of the “same” image; one for you, and one for potential stock/editorial/commercial usage.
