Those characters keep showing up in these pictures. It’s very dark in there, but I only pushed the ISO up to 1600 for a 1/50th shutter speed. Why was that? Because I was also recording video, which you want at 1/50th of a second.
Otherwise, I’d have gone for ISO 3200 and gotten the speed faster to get less blur. Everything is a compromise, but with a little Lightroom wizardry, you can make those compromises look pretty decent.
