In view of what pjz99 said regarding intensity of existing lights, etc., I cancelled my render... deleted ALL lights and added 1 infinite light directly above the scene I am rendering.

It has gone through the calculating phase and is now rendering with some interesting results :-)

The overall brightness is almost the same as the 6 lights I deleted.

Objects on top shelves are normally lit. Objects beneath those shelves are in varying degrees of softer shadows... not dark black shadows as one would normally get with just the 1 infinite light above the scene.

The render has a fair way to go yet and is by no means perfect... but... I can see the benifits of the indirect lighting... I guess I just need to adjust settings until I find the optimum setting.

Certainly looks as promising as anticipated. :-)
