SUMMARY

The discussion centers on a peculiar visual phenomenon observed during an explosion featured on Mythbusters, specifically around the 1:35-36 mark. Participants speculate that the strange cone-like shape above the explosion may be attributed to various factors, including camera artifacts, a Mach disk effect, or internal reflections within the camera lens. The consensus leans towards the possibility of internal lens reflections due to the symmetrical nature of the phenomenon. This analysis highlights the intersection of physics and cinematography in capturing explosive events.

PREREQUISITES
  • Understanding of camera optics and lens reflections
  • Familiarity with Mach disk phenomena in fluid dynamics
  • Basic knowledge of high-speed photography techniques
  • Awareness of visual effects in film and television production
NEXT STEPS
  • Research camera lens internal reflections and their effects on image capture
  • Explore the physics behind Mach disks and shock waves
  • Study high-speed photography techniques used in explosive event documentation
  • Investigate common camera artifacts and how they occur in various shooting conditions
USEFUL FOR

Filmmakers, physicists, and photography enthusiasts interested in the technical aspects of capturing explosive events and understanding visual phenomena in media.

Here's an explosion from mythbusters.
At about the 1:35-36 mark, there is a particular camera angle where if you go frame by frame, just as the explosion starts, there is a weird disconnected phenomenon right above the explosion(kinda like a cone).

Could anyone explain what that is?
A camera artifact?
A mach disk-like phenomenon?
Something else?

Because of the symmetry, I'm thinking it is an internal reflection in the lens of the camera.
