When you think about your family photos, the first thing on your mind should be the setting you want to place them in. You want to use the setting to convey the mood of the final image, so choosing wisely is important. If you have a particular place in your home that you would like to display the photos, consider this when choosing a location. For example, a formal room would lend itself more to a darker background that would accentuate the subject, whereas an open, airy sunporch would be better suited with images from, say, the beach.
Another consideration to make is what story you would like to tell with the final piece. An amusement park at dusk tells a far different story from under the pier in the morning. Having your photograph tell a story in the eye of the viewer is crucial to creating a meaningful image.
