Bryce 6.1 - Logo added in CS2
I know this isn't the most interesting render in the world - but just to show off a technique.
I'm not good at writing tutorials - but here goes
I made 4 renders of the above scene as 700*700 - with same atmosphere as "Lonely tree" - I had 1 light in each render - which i pulled further back in the scene for every render and with settings 75,50,25 and -25 in strength
Then i used photoshop automation to make a HDRI - with the darkest image set to -4ev the next to -2ev the next 0ev and the last +2 ev - then i adjusted the result to something i found suiteable. I used the resulting HDR file as IBL in the same scene and rendered it. It was amazingly fast render- i tried the same with a "proffesional" HDRI - and the result was almost the same - but with a render time about 10 times slower. I know i haven't used the IBL as background - because it was not suitable for that - but the lighting is almost as a pro HDRI
Fullsize is 1920*1200
Should be seen in full size view for the details
Comments most welcome
Hope you'll enjoy
