A pencil drawing can be a sophisticated piece of art, as well as a primitive sketch explaining your electrician where you want the sockets mounted.

Same with photography. Art is not defined by the technical means, but by the person behind it and the intention of the work.

Stupid example: Making P&S snapshots of our family under the christmas-tree this month most probably will not be art, because it was never intended to be art in the first place, it's purpose is to record a memory. However, if a photographer travels from country to country for ten years, making hundreds of pictures of families under their christmas-trees, then makes a selection of 50 photographs and mounts them on a 5 x 5 meter board and displays it in the pedestrian zone of a large city, you should consider that person an artist.
