...for your professional approach to displaying the relative brightnesses. Great job! As you have pointed out, its impossible to show how a beam pattern appears to the eyes. Even if you used HDR techniques to approximate what your eye/brain combination perceives (your eyes having a much higher dynamic F-stop range than any standard digital camera) the result would be only as YOU see it and not how anyone else sees it, and the way your eyes see it changes as you scan around a scene anyway.
Your setup looks great - it seems the Hella projector throws more light down the road where it is needed and less in close to the bike. Does that seem to be the case?
