For this exercise we are asked to take just one photograph in which it can be seen that something has happened. The reading suggests that this image should be powerful. Something that tells a story in just one image.
I have just such a photo that I took after the riots.
I went to Brixton after the riots. I think this image is as powerful as many of those the media took of action shots at the time of the rioting. This image shows what happened. Even those caught up in the heat of the moment would have to reflect when seeing the results as shown here. Shortly after I took this photo most of the shop windows were boarded up, which in many ways hid the problem.
