I have been making some images recently that attempt to capture, for me, the ‘feel’ of an event or action. Photographers talk about “the decisive moment”, the title of‘s most famous book (although the French title is actually “Images on the Sly”). I am thinking more of “the decisive motion” – what event, movement or attention-grabbing object fills the frame in memory? I have been taking short sequences of video and creating a single image from all of the frames, to locate images that capture my sense of memory.
The best of these include motion heatmaps, images coloured by the amount of movement in each pixel. In a classroom this should be a map of the things that matter (the teacher, friends, intentional moving images), rather than distractions (fidgeting, wafting posters and reflections). The image above shows areas of high motion (red) and stillness (blue) in a classroom.
