Optical Illusion: Create One With Any Color Photo

Step 3 Creating a Negative Image

Import your chosen photo into a photo editing program. Then simply choose the "invert" (or "negative") editing option. This should convert the whole photo into a negative image. Then save it. Make sure that you keep the original color photo that you imported, if you want it. For instance, I used Photoshop and saved the inverted photo as a copy. I still retained the original photo.
