In my Perspective & Proportion class, we were given the task of designing and rendering a vehicle using a particular technique of perspective. I'd had this notion of a vehicle hinged in the middle since I was a kid, so I drew that. I laid it out on several layers of tracing vellum in pencil, then transferred it to illustration board, inked it, and did the shading in Prismacolor grey markers. In the future, I need to get reference for suspension on construction vehicles and do more detailing. This looks more like a toy than a large machine.
There is an optical illusion that can occur when highly saturated complementary colors are placed next to one another, particularly if the lines are thin, where it appears as though there is a line between the colors, even though no such line exists. This effect is called color vibration, and it is demonstrated in this representation of an orrery. A secondary purpose of the images is to show how changing around the colors can affect the perception of an image. The two orreries are identical in form and use the same color palette. Only the arrangement of colors has been changed, but the orrery on the left appears to stand out from its background, while the one on the right almost looks punched out of the background. To me, at any rate.
I liked the composition of this photograph, but the camera's autofocus liked the girls in the background more than Mike. I colorized the image and put a big blur on the background to try to make Mike the focal point. Obviously, taking the picture right in the first place is better than fixing it in Photoshop.
