Now we need to go back in and correct some lights. Figure 11 below shows the original set up all lined up in rows which gave us the above results. Figure 11 also shows how the lights were changed to correct the hot spots and dark areas.

Fig. 11

I don�t know how well you can see it, but I moved some of the lights in the back row closer to the back wall and cabinets to help light that a little better. I then moved and deleted lights around the table and chairs to eliminate some of the hotspots. Once I finished that I test rendered and got the following results (Fig. 13).

After moving the lights I still have the hotspots. So a good thing to do is try moving the lights first. If that does not work, then delete some of the lights causing the hotspots. I deleted the lights causing the hotspots on the chairs and moved the lights causing the hotspots on the counter. I chose not to delete those because I need the light on the back wall. Once again render it and check the results (Fig. 13).

Now all the hotspots are gone and I have a nice soft light to the scene. On a side note, this entire scene renders in less than 3 minutes. No calculating photons or light emission like in global illumination. It is a fast effective way to get a nice look to your scene with minimal light linking needed. All of the point lights are effecting everything. The only linked lights are the few extra spotlights I added for effect.
