Capturing images that grab attention is a goal of any photographer. It’s exactly this skill that separates a good photographer from an average one.
An image can grab the viewers attention in many ways. A typical one the last years has been through the use of strong and vivid colors. However, such images (with many exceptions, of course) tend to give only a momentarily “wow”-effect, just to be forgotten as quickly. You want to do more than this, though. You want the viewer to remember your image. You want them to come back and look at it again and again. You want to trigger a certain emotion.
