Today I went to the public library to check out some photography books. Before doing so, I noticed an interesting looking black man with distinct features and a kinky afro who looked to be in his mid thirties to early forty's seated in a chair, legs crossed, intently reading a book. I immediately ran outisde and retrieved my Pentax K-1000 from my vehicle. Upon my return, I promptly sat at a table directly in front of him no more that 10 feet away. I removed my camera from its case along with books from my bag and acted as though I was reading them as a means of learning how to use the camera; all the while sniping shots of him as he read. Then it happened. An elderly white woman sat in the next chair to the immediate right of him. She looked to be in her early seventies. Their was maybe an 8 feet gap between the both of them. She was wearing 1960's style clothes and eye glasses, with a hairdo that matched the time period. I immediately knew that I had the shot of a lifetime. I already had visions of the awards that I would win with this photograph. I promptly switched to my wide angle lense so that I could get the both of them in the frame. I waited, cautiously looked through the viewfinder; adjusted my aperture and shutter speed. I hesitated a bit, so not to alarm her, slowly advanced the film to the next frame, gazed through the viewfinder. Before I could pull the trigger, she became nervous, and moved to the other side of the library; thus leaving me in the grief stricken frame of mind that I am now in. I started to tell her that there was no film in the camera, but I was already feeling guilty for sniping shots of the man who was reading so I said nothing. Along with the fact that I do not like to lie. Originally I was not going to bring my camera with me. Half of me is happy I did because of the intersting shots I captured (sniped) of the man reading, while the other half wishes I hadn't because of the shot that got away. Does anyone else have a similar story?
