That is impressive. I'm going on an architectural shoot on Sunday and will certainly try the technique.
I tried out the method at Shakespeare's birthplace in Stratford-on-Avon as a test run. I deliberately waited until people walked in front of the building before taking the shots (about 22). Light-wise in early morning the sun position is such that one cannot get a good picture but it was only a test.
Very impressed with the outcome. Will certainly use the technique again for proper pictures.
