1. Why square? Because Delft chose it.
2. Why the little Panasonic micro 4/3rds with only a pancake lens? Because it is small, not in the least intimidating, and easy to carry. Battery life sucks of course, but that's what spares are for.
3. Why not all b&w - why are some in colour? I wish I had an answer - I wish I had one style of photography that says "Patrick Dodds took that picture". But I don't.
4. Why the obsession with photography? I don't know - you'll have to ask Photography herself - she chose me.
