= 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.

=== 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.
