Fascinated by the interplay of light and dark? Wondering what separates a compelling image from one that's more, well, mundane? Perplexed by why this megapixel camera is better than that one? Me too. So come and help me learn more about optics, perception and artistry in Mechanical Engineering 24: Let There Be Pixels. In this seminar we'll look at basic optics, human perception, the physics of image acquisition, and the creation and modification of images (photographs, paintings, and so forth). Participants in the seminar will be learning, doing, and teaching, along with the occasional moment of spacing out.
