Take a look at Kaushik Chatterjee’s Dasera photograph. Look at the man in his unusual makeup, his colorful clothing, and the people behind him. Imagine the traditional ceremony or ritual they might be enacting. Try to avoid reading the comments below first, which explain the situation–allow yourself to come up with something totally spontaneous.
If for some reason this photograph is not available when you read this and go to look, then free-write about a traditional ceremony involving processions, brightly-colored clothing, and anything else that comes to mind. You might write it as a tourist witnessing the event, a participant, or a local witnessing the ritual. You might also choose to write it as fiction, memoir, etc.
