Ok, but there’s more to picking the right spot than just the location. As important as location is, your sunset will almost always be lacking the one essential ingredient that will make it special – a dominant point of interest. And just what might that be? It’s that extra element that gives your sunset an anchor, a sense of scale, a point which will draw the viewer inevitably into the picture.
A photograph of a sunset by itself just doesn’t work. After all, one setting sun is much like any other. Even if you manage to capture the gorgeous color, without a dominant point of interest the image will still end up looking rather boring. Now, having said that I should tell you that, without some forward planning, a dominant point of interest is not an easy thing to include. It might be the silhouette of a sailboat on a glittering, backlit ocean, a barn, a horse, a cow, a tractor, or even a lone tree in the foreground. It could be the silhouette of two lovers walking hand-in-hand down a country lane, a little girl with a small dog on a leash – I’ve used both of those – and I’m sure you can come up with many more ideas of your own.
