I decided to start a thread on some of my experimenting with outdoor lighting and rendering.
So here is the scene I am going to be using:

I designed/modeled it to have complex shadows, relfections, and have IOR somewhere (the water (1.33))

I have updated that lighting setup slightly after the last render, I added 2 bulbs underwater (as suggested in this thread to give some shadow detail, and I also added a Lane T on the bottom of the pool.
Ive been enjoying rendering to OpenEXR and using its high dynamic range (32 bit too) and buffers to get additonal tweakability.
Next up is the midday daytime look!
