Rob Prideaux has a whole collection of images associated with fire at the link below. While he doesn’t specify how exactly this image was created, he does state that with the exception of only a few touchups, they are all real images, not created by CGI. Fire is obviously aesthetically pleasing, but he takes it to a new level, by using physics to create new shapes – typically fire isn’t in a ring as it is in the image above. By burning real objects and capturing the image from above, the flames look different from what we usually see. The natural convection of the air is pulling the flames towards the camera, instead of vertically up the image.
