Photographs.
single image -> paired image -> picture story -> picture book ->
Photography has become a storyboard. The illustrator’s tool for advertising clients has become the means of telling a photographer’s tale.
Occasionaly, the images form close units, revealing what they are about. More often though, the one image lifts the weaker one. Sometimes, early in working the problem, the weaker lowers the stronger, as it is strengthened. Like children swimming too far beyond the shore, beyond their legs.
