I have recently worked on a few proposal illustrations for outdoor events and shows with great success. The method I have been using places models I build (or have supplied to me) onto aerial photography at accurate scale. This gives a very realistic impression of what a show or event will look like in real life and how everything fits together. I can render the scene from multiple angles and even control the direction of the shadows. The example here shows an aerial photo with models of boats, docks and buildings I built and added. If you have an upcoming event and would like my help in planning or proposing please contact me.
