Recalling an incident that happened to me when I was taking photos at the east coast park beach. I was taking at the jetty like platform. Image is of some clouds and the sea at the distant horizon. Around this time, there is a guy fishing in the background and a young couple exercising. The couple must had heard my digital camera beeping while I was snapping away. They then approached me and asked me if they are included i the pictures I took and wanted to see if they appeared in the frames. I told them "yes, both of you appeared in the pictures". Then, they asked me to delete the picture that I took in which they appeared. I was abit taken a back but then obliged. But after thinking a bit longer on this incident, I questioned myself if I have the right to decline their request....Has the photographer no freedom at all in taking pictures with some people inside the frame? Its not that I purposely zoom in on them and take a portrait but they form part of the overall landscape and they did not even take up more than 30% of the image.
