Coming back from Glasgow on the train last weekend I became aware I was the subject of another passengers photos. I don't know how many he shot off , but when I look over he quickly was doing something else. I thought this was quite amusing so I looked away. After about five minutes he was back at it. I could just make him out in the window reflection. I smiled to myself and let he get on with it. Who knows, he may have got a cracking shot. I'm not that comfortable taking pictures of others in this way, but I love some of the candid/street work others post here. Have ever been snapped ? Would you, do you mind ? What would be your limit regards length of lens used ? I guess some things would be obvious like if you were out with your family. Is it acceptable or not ? Me, I'm not sure i really care. In fact sometimes I feel flattered. I even think how could I make the shot better for them. Btw. He was shooting with an iPhone. I know they can take great images. Cheers all.
