Saving 32-bit images from Live Viewe

[martincarlson]

I've read the help file and searched the forum but I'm still not sure if I understand everything correct.

To render/save 32-bit image I have to use Picture Viewer? I cannot save from Live Viewer?

Live Viewer does NOT render in 32-bit? So saving 16-bit PNG or EXR is basicly saving 8-bit data in 16/32-bit container?

Confused.

no confuse. it displays 8bit but can save 32bit via Exr.

Aaah! Very good. Thanks.

And saving tonemapped vs not tonemapped? What's the difference? Camera response baked in?

[martincarlson]

Can't find good answers on the forum. But I guess the tonemapped exr has less dynamic range?

[aoktar]

Tonemapped floatbuffer is clamped by max 1.0 value. But floatbuffer is not clamped.

[martincarlson]

Ok. I guess I'll have to settle with that answer, even though I don't fully understand it. Thanks!

float tonemapped: camera response is applyed to output pixels. Resulted colors are between 0.0-1.0 per each R,G,B,A.
floatbuffer: this is raw output our rendering with gamma=1 and not limited to 0.0-1.0 values for each RGBA. If you compare in pshop you'll see the illumination is high than 1.0 for sunlight, etc....

Also gamma=1 and raw colors, that's the reason why it's darker and not same as in LV when you have camera response.

Ok! Thank you.
