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 scattering around the sun.

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.
