I believe that the more one knows about art, the more creative a photographer might be. My studies of art have enabled me to see patterns and understand composition better. Perhaps the same is true for other photographers.
The following photo was made in Zagreb. Here I cropped it to even out what was seen of the chairs, to serve as a frame. This received a purchase award in a county competition for photography.
Keep in mind that there is nothing wrong with photographing your own empty bottles and cups; they can also provide a foreground image for a broader shot.
The key to an image like this is tight cropping. On occasion, you might want to rearrange a bottle, perhaps to show the label, but otherwise it is surprising how often still life photographic opportunities present themselves. For those of you who never considered the merits of an image like this, think of it as part of a long tradition.
