One of the sad things of our age is that photos are often better than the real thing due to sensors that work well in low light and long exposures. In Yosemite there is an annual "lunar spraybow" event. The photos are amazing, but when you're there in person it's just a faint shimmering. For a red/green colorblind guy like me, it's a non-event since that end of the spectrum is dominant.
So if you're looking at a 2-second exposure with an F1.2 lens, you're not seeing anything like what people saw live. I know this was true for the impressive photos people took here.
