Note: Reference this diagram if over or under exposure is mentioned. usually by 1 or 2 stops. Also if your display or display card shows colors in the "thousands of colors" range you may see unnatural rainbow-like rings and color banding in the photos. Everything should appear smooth with "millions of colors".
For an idea of what's involved in correcting color and exposure of the images:
Original shot with the TX25C2 on the left, corrected version after color, exposure and white balance adjustments on the right. The original on the left was more color saturated compared to what's being observed so that had to be bumped down. Some green had to be taken out and the background exposure needed to be brought up. That and numerous other tweaks. It takes about 10-15 minutes per image if things aren't too bad.
What can't be adjusted is when a camera over exposes brighter hot spot areas in the center and consequently under exposes the outer edge of the spill beam. So in this case while everything is now very close tint wise and for the most part exposure wise, I'll note that the center of the hotspot is overexposed by about 2 stops. The outer edge is underexposed by about 1 stop.
Another example with the quad R4-5C
Original on the left. Corrected on the right. This one didn't have as big an issue with hotspots due to the wider flood but colors needed a big tweak. I'll note that it's over exposed around the center by about a half stop (barely worth mentioning), and underexposed at the edges by about 1 stop. So for the most part the corrected images in the thread are exceptionally close to what's being observed in person.
