Christopher Konecki is a San Diego muralist who just posted a video that gives quite a bit of insight into how a mural is created. Christopher produced the video to show his creative process from start to finish. It details the initial idea, sketch, revisions and painting process and was captured via iPad pro. The painting was documented by time-lapse. Check out the video below and for more videos by Christopher Konecki, check out his Vimeo.
