One advantage wide angle lenses yield is bringing things into relation over a wide angle of view. For instance something real near and at the real edge of the picture and the rest of the image filled with the rest far away. (Not exactly the golden rule…)
Small angle lenses in contrast give you the chance to relate things to each other which are staggered behind each other (compression effect). But here there could arouse the problem of out-focus blurring of one of the objects. For this technique you should be far off to all of the objects.
