Ian.H (of dSRC fame) knows a thing or two about lighting. See the dSRC forum for his thread and tutorial on making cool lighting scenes. It's all over my head to be honest, but one day I might get round to learning...
Would it be possible not to use [img]-tags in threads like this, especially if the pics are that huge? AFAIK it slows down the forum and it is not very handy if you have to scroll not only vertically but also horizontally. The upload-function of this forum works fine, you get a small thumbnail and by clicking on it you get the full picture. Or maybe there's an automatic resize-function in this forum that could be enabled? Admins?
