Cycles and tone mapping


I started to use Cycles to render an animation and have some questions/requests:

  • I would like to get one frame buffer only without to close the last rendering. Is this possible now or a wish for the future?

  • I miss the classic “Reinhard” tonemapping with exposure, burn and contrast. Or is it the Logarithmic?

  • How to define the tone mapping so that it is be used for all renderings? Every time I press render I get new frame buffer with default tone mapping. Is there an option?

  • Most I miss to define a custom curve for the tone mapping. It’s my favorite way at V-Ray. Could it be possible for Cycles?
