Good photos have clear foreground and background. See the next page for further explanation. There are clear places to put the model. Such an arrangement should show things like the relation of your site to the model a good scale. It should tell your story. A composition with too much site doesn't feature what you're designing and a model dominated frame is a bit dry.

Think ahead to working with Photoshop. A photo with too much going on in it may be hard to cut apart. Too much texture can be tough and make the inserted model look too abrupt. Both photos to the left are hard to eliminate the trees. In the top one it may be possible to eliminate the tree, but not in the bottom one. On the upper right, the tree is such that the trunk is all that interferes with the existing house. Eliminating the existing would be easy. A taller intervention might cause problems.

Photos need to be a scale that matches your model. The photo in the bottom right is good for a view out a window, but placing the model into this landscape will swallow your model. Scale would be hard to discern and should really make you question your project's intention.
