Worlds colliding

My take on a "bad" photo, from Marc Levoy's first assignment.

We've been avidly watching Marc Levoy's introductory course on digital photography, recently provided online for free by Google. For people like Linton and me who are entering the creative world of photography with scientific backgrounds, finding out more about the physics of optics and the maths behind Photoshop, makes it more approachable. I'm guessing we're in a minority! Last night's episode was especially in our wheelhouse as Mark touched on the psychophysics of vision, or how the human sensory systems gathers and interprets information in its environment, and how this impacts on things like minimum resolution for displays. Like all things involving the human factor, the physics is the easy part! And even if your eyes glaze over at some of the tricky bits, there's more than enough things of interest to keep most photographers going with the course.

We're also enjoying the assignments. The first one is to deliberate take some "bad" photos, where "bad" involves breaking the rules and circumventing your camera's default behaviour (e.g., blurred, poorly exposed, poorly composed, out of focus, or wrong white balance). The aim is to, of course, get an artistic shot by breaking the rules - a most satisfying start to what I assumed was going to be a "thou shalt" approach to photography.
