I don't think I need to add captions to each photo. In my view, if a photographer adds a caption which will give an interpretation of the photographers' idea and that will influence the viewer.
The Author(in this case the photographer) is dead. All photos are open for all sorts of interpretations from all sorts of viewers. My views are not better than yours or yours are not better than mine. As the creator of the photograph, I am not sure I have any upper hand. We all contribute to the understanding of the image.
