Scroll right (and down) to see the full extent of High Rise.
Using your Browser's zoom you can see High Rise at different scales. ("Cmd -" and "Cmd +" or "Ctrl -" and "Ctrl +" work as shortcuts on most browsers)
How it's made: I take a high-resolution photo of a tall building (Left, made with a Canon 5D Mark II at full resolution). The building is "straightened" in Photoshop (Right).
After the building is straightened, I mark off each floor at the same location (see horizontal guides drawn above). Each slice then becomes one frame in a GIF animation.
Isolating each building storey in a quick-moving animation gives the appearance of the building stretching taller and taller.
Repeating the GIF vertically creates the illusion of a tall building growing taller in the final High Rise composition.
