HDR question

[fantomaz]

Hello all,

 

i am rendering some outdoor pictures and i am in the need of a cloudy sky.

So i used a HDR with a hemisphere to get that sky. So far, so good.

 

But the original sky HDR is too overexposed, so i played with the clamping

and remaping sliders. Now the sky/clouds looks good, but overall the sky

is too dark. Is there a way to get a more brightly sky without loosing the

details and without overexpose the sky/clouds?

 

Here are the two versions so far:

This is too overexposed

 

This has the right details, but its too dark:

 

Can anyone tell me a way to get the detail level of the second picture and the brightness of the first?

 

Thanks for looking

What is the bit level of the sky file?  If it is 32 bit then it has more range.

Hi all,

 

i tweaked a lot with the y and x range values and send customer some pictures.

Finally one was good he answerd  :shy:

 

I will show the picture next days, when customer gives his ok.

 

Some specs:

Polygone: 25 Million

Psunami

Motion blur (vector)

 

Rendertime:

Octo 2,4MHz with 16GB Ram -> 60 minutes

Quad 2,66 MHz with 8GB Ram -> i stopped because of super heavy HD action (sounds awful) never finished building BSP.....

 

I liked it  :)
