No post-processing here, I've simply used Yuki's «Fin de Siecle» Windlight setting.
I like this music with the picture.
Someone asked me for a guide on how to add Windlight settings. This works for me:
1. Ctrl + click (Mac) / Right click (PC) the Second Life program file. Choose «Show Contents».
2. Open a folder called Contents.
3. Open a folder called Resources.
4. Open a folder called app_settings.
5. Open a folder called Windlight.
6. Put all the .xml files into the Windlight folder.
7. Re-start and enjoy ^_^
