The Rule of Three Colors
I’m sure most of you have heard of the Rule of Thirds – which states that if you divide a picture up into thirds, the subject generally works best when it is not in the middle third. I think this rule works quite well, though as with everything in photography there are times when it should be broken.
There are a number of other “Rules” in photography, but one of those I like most is what I call “The Rule of Colors”. I’m sure it is not new – and there may be a more widely known name for it, but I did notice it myself before anyone mentioned it to me.
To illustrate this rule, what do these two pictures have in common?
