Title: Contrast Brightness and Luminosity...
Post by: aymenk2003 on August 28, 2009, 10:40:35 AM
I've a problem with the image rendered detail (Contrast Brightness and Luminosity) ; when I see the other renders in the forum they are too clear with nice color and my reder should be post-worked to get these details and bright color ....
I tried to tweak the atmo setting and the sunlight setting ...
Is ther any known config for that ...?
I join a rendered image before postworked  and a second that I want to get ...

I render settings "Effects" tab increase contrast to 6 or better. Also I find that the default haze color is sometimes to light. Push the slider to the left to darken the haze color. Then try a crop render. If it's not enough you can lower the render camera light exposure. I'm sure there are more ways to increase contrast but this is a start and it works for me.

Are you assuming that other renders on this forum aren't post-worked? I think most of them are.

As for obtaining the results you want without postwork... well, it's probably possible to get closer in some areas with a lot of tweaking - I'm sure that the atmosphere colour could be changed that way, but fiddling with the various controls that affect colour can be time-consuming and sometimes frustrating. It's really up to you.

I almost double the tipps of Buzzzzz, but I never dared to go beyond a contrast of 1 ;) ... I lower the gamma, too.

If you are working with the .exr output then postwork is the only way to get the contrast and colouring that you want as the .exr file does not apply the contrast/gamma settings set in the renderer.

If you don't use the .EXR you should, simply because it captures much more information, allowing you to create images at different exposures from just one render. Although to get the full benefit of this, you also need a program like Photomatix Pro, that allows you to combine exposures into an HDR image.

It's one of the four options for saving, called OpenEXR: just click on "Save as type" - it's that simple!
