 There was a study done by Princeton University that said it only takes a tenth of a second for someone to decide whether or not you are good looking. This also applies to your photography and is one of the reasons why it is so important that your photographs make the best use of that first impression. One of the ways of helping to bring depth into your images is framing. So all you really need to do is to take various elements within the frame and to use other elements to frame it. When you start doing this, not only do you draw attention to those areas of the image, but you can use frames within frames, within frames. Shadows are the second one. Shadows, they can do it all, man. They can create contrast. They can create patterns. They can create repetition. They can create negative space. If you can do it, shadows can do it. Some of the most eye-catching arresting images that I've been seeing with images that have a strong shadow at the heart of them, that it adds up so much into making a very impactful photograph.
