In this image you can see jars of jelly lined up on a store shelf. The photographer focuses in on one particular jar that draws your eyes to that jar. Your eyes are drawn to that jar because it is in focus and clearly visible to read the label, while the other jars are blurry. It almost appears as though the jar is also sitting out a little bit more than the others on the shelf to help draw more visual attention, but I cant really tell if that's the case. It may just be my eyes playing tricks on me ?!?!
