Another one from London. This time, I was walking up Regent Street toward Oxford Circus. This is prime shopping district, of course, and there are many stores with bright signs in the window. As I passed this particular store, I noticed the large screen that was projecting a white background, with occasional text advertising this or that. I must have made 15-20 exposures over the course of 10 minutes, just standing in front of this sign as the passers-by...well...passed by. As is often the case, the last shot (this one) was the best. I noticed this father and son walking up the street, and waited for them to get into position. Fortunately, they were not obscured by anyone else in the frame, and I was able to make this photograph.
