Batch exposure

HI all,
Maybe this is a stupid question but anyway... :lol:
When I have my render done (plain 8bits :oops: ), there is a way to batch exposure values from -4 to +4 for example and then create a hdr image compiling all the differents exposures values?
I´m a noob in this HDR thing.

Cheers
JC

Have you tried saving the render output in 32-bit such as EXR or HDR?

Yes I tried that, but I don´t know if "batching" the exposures and merging them into a new HDR is going to make the image better balanced in tones.

You will not get good results doing this. Compare it to taking an 8 bit LDR photo and saving out different exposures and then trying to merge that into HDRI.
Tom is right, a Maxwell output in 32 bits will alow you to do all of the tonemapping you want. I suggest Photomatix for tonemapping. :)

Thanks Tom and Brian, I guess my workflow or the ideas that I had were just a little wrong :lol:
Thanks again :)
