Another idea I have been toying with is 'finding' alphabetic representations in the real world to photograph. I first stole the idea from artworks representing 'significant words' in shops like Texan Art Schools and An Eye for Art, and have since read about trying to 'find' the whole alphabet on various photoblog sites.
When I unpacked the chillies from the shopping today... Volia! They landed on the bench in the most uncontrived, perfect 'V'. So I made the most of it. I wonder if my alphabet might have a food theme?
