I"d always wondered about the "right" to walk up and just fire away. I always feel uncomfortable just snapping pictures of people I don't know.
I do like this photo though and I agree that the guy in the left side of the picture really brings a sense of fun to the scene.
I have been a street shooter for many, many years and after a while you learn to develop a sort of 6th sense when it comes to shooting people in public. Usually, most street shooters go for candids in which the person being shot has no idea someone is taking their picture. I shoot like that as well, but I also like to engage the subject evrery now and then. I use a combination of both methods.
I had been watching the group for a few minutes and noticed how lively and playful the girls were but I did not see the shot I wanted. So, I just walked up and got down on one knee and sure enough, the gals started playing to the camera and I got the shot I wanted. You can see that the fellow wearing the cap is eyeing me somewhat suspicously, so after I got the shot, I smiled and gave them my card. I find that if you are very direct and smile a lot, most folks understand what you are trying to do. However, every now and then, you will come across someone who does not want their picture taken, and will let you know, and I just lower the camera, smile, and move on. :hail:
And as far as the guy peeking in? That was a complete fluke. Normally, I am very aware of what is going on in my framing of the shot I am taking, but I think he stuck his head in at the very moment I snapped the shutter and I never saw him until I got home and loaded the photos in the computer.
