Realistic Camera - Lens Flares

The original project proposal can be found at JulienChaumond/FinalProjectProposal.

My idea was to extend the realistic camera model in order to simulate some of the interesting lens-internals related phenomenas in real cameras: lens flares and glass scattering.

Motivations

Sources of inspiration for this project included:

Fresnel Equations

Light Ray Tracing

Mie Scattering

Building the scene

Environment light

Experiments

Influence of the position of the sun

Shape of the aperture diaphragm

Background cloud texture

I tried to use a cloudy sky as a texture for the background, however it looked kind of funny so I ended up not using it.
