What makes a good photograph?

This, of course, is a very subjective question but I wanted to try to answer it in the most basic, simple way possible.  If we were to deconstruct a good photograph to its most basic element, what would it be?

The Subject.

Sounds too obvious, right?  But think about it.  When you have your camera out and taking pictures, think about your subject.  When you look at your photos, is the subject obvious?  Is it clear to anyone who looks at your photo, what the subject is?  

Keep the following questions in mind: How is attention focused on the subject in the photo? How is your eye drawn to the subject?  Is it the focus, the depth of field, or how it's composed? 

You should try to simplify your photos as much as you can.  Try to take out the distractions; keep your backgrounds subdued.  I know you’ve heard this one: KISS, Keep It Simple Stupid.  Don’t overly complicate your photos.

Remember, it's not about what camera you have.  These are principles that you need to know, no matter if you're taking a photo with your cellphone or a Canon 5D Mark II. To quote one of my favorite photographers, David DuChemin, "Gear is good, vision is better."
