@0x35c these shots were both 1 second exposures, handheld, at 1.7 aperture and 200 ISO (my camera's base ISO, which I never leave). I kept the camera steady for most of the second, then swung it hard near the end. I took like 6 shots doing this and these two were the most pleasing.

In post I gave each shot a custom tone curve to deepen the shadows and brighten most of the rest. Topped it off with some RGB curves to give the image more of a blue/orange contrast. I do my edits in rawtherapee. c:

i genuinely wonder how did you manage to get everything clear while moving the camera for the lights ? (i'm new to photography)

the lights look like scratches on the right, i love that effect! sick colors too
