Live illustration - 3 screen set up recently at The Grand Hotel, Brighton.
Although this photo is just low res, the image I was working on was 4K. Mac connected to Wacom Cintiq and large monitor on stand, showing work in progress throughout the event. Further linework was produced and then colour added, along with captions. It all worked well and finished illustration can be sent as a jpeg to be included in a PowerPoint presentation or printed out.
