In this project you are to create an image that could not happen in real life. This is similar to the surreal montage in photo 2. However, a simple double negative will not do. You can combine images and mask layers to create this (if you do not mind technical editing in photoshop). Shooting your subject in the studio with the white background will help with this since you can Select/Color range to make selection easier. More editing= only 3 pictures needed in final submission
If you do not like editing in photoshop, you can shoot a series that defies gravity. This will not require as much editing. For analog people, you can shoot double exposures being very mindful of your subject placement & setting as to not completely look like a double negative. (white background/sky is key).
