Over the years I've made several attempts to appreciate IBL lighting with little success. From what I can tell, an IBL light simply provides a general cast over the entire scene. This is the same whether you are using a fancy shiny globe based image, a regular (flat) image or no image at all.

So why all the fuss about IMAGE based lighting? Other than a general, scene-wide cast what is the image supposed to do for you?
