CCD vs. CMOS sensors.
Actually, the formulation of the color filter arrays changed, moving from Kodak to mainly Fujifilm dyes. This occurred around the same year as the sensor shift in 2008.
I did that last Friday. It was a night parade, no sky light, with inadequate street lighting, on a narrow two lane old-time urban street. 50 mm was definitely too long (on full frame) for many of the shots but I managed to place myself at a turn in the road so it wasn’t awful. I exposed for the highlights, which consisted of a multitude of Christmas lights on each float, and a lot of the shadows were indeed rather dark. The lens was a f/1.8, and most of my shots were f/2.2 at rather elevated ISO. My keeper rate was well below what I’m accustomed to. Definitely I’d use a wider lens were I to do this again, like maybe my 28 mm f/2.8, and I’d shoot it wide open.
