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

[Diego Pino Navarro]

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
