It's the photographs you'd like to take or rather: the ones you'd like to be known for taking.
It's the desire you have for the things you (secretly) want others to say about your work, and the qualities they'd notice.
It can be a force for good, pushing and nagging you to learn and to practice, to invest and to investigate, to make new connections and allow yourself to be challenged, and inspired.
It can also seriously get in the way of taking a photograph.
I think I notice photographic ambition most intently when I set it down, and pick up the camera.
It's the lightness I feel, the absence of its weight.
When you put ambition down, that's when the magic happens: when the world starts to move, and bend, and dance with you, to offer pattern, texture, colour, light, to offer invitation and challenge after prickly challenge, not of the abstract kind but the real: how to show the look of this day, this moment, this light, this patch of earth, never mind how it could look, but simply, how it does.
