Re: [Yafray-devel] Producing HDR images with yafray

[Mein]

Hello,

Maybe you should post on the forum about the importance of the mailinglist. 
I think this mailinglist is here to talk about the bit more complex 
questions regarding the code.

But maybe I should have posted this there... excuses :)

Mein.




Hi Emmanuel,

Are you generating this TIFFs  for 35mm compositing (32bit color?)
I think you should post the question about intensity above 1 in the
forum, there is more activity there, eeshlo should know where to dig in
the code.

Would be nice if you could post the code for this mod.

Bye

Diego
