Simulating Dark Adaptation 2003-12-08 - By Llaszlo Kiss
Back
This might be too simple:
Put a plane in front of your camera, give it a white,
fully transparent lambert, add some glow intensity,
hide source, play around with the incandescence (you
could even map it with some noisy ramp) and your halo
settings. This is for the overlit/burnt out effect, if
you want to make it dim, don't hide the source, use
black for incand. and lower the transparency. Does
this help?
