I have learned to pay attention to not just the positive space in a composition, but also take note of the negative space. The space around a focal point it just as important to a composition as the focal point, itself. This is very important in our current line studies project. Being able to compare and create a conversation between two pictures and their figure/ground is important.
Being able to train my eye is also very important. It took me a while to catch on, but once I did, I understood the connection that was to be made.
Framing is very important in the design world. It bring, or takes away focus from an image. The impact of am image is skewed by how it is cropped, if cropped or framed at all. This is important to the process of tracing and making vector images for our book. When cropped and framed the correct way, the line studies match up, or create a juxtaposition, with a found image that we are paring it with.
