Okay, I am a big-time noob. I took my only camera, a 2006 Canon PowerShot, to an experimental rave set. I put the camera on auto-night (not knowing how to adjust the manual settings, of course), and hoped for the best.
Well, now I have half a dozen DJs with an exposure of 1 second and blurry-as-fuck. Since then, I have been messing around in a dimly-lit room, and now know to turn up the ISO and turn down the f/ratio to keep the exposure time low. A first lesson ๐. Let me know if I have the right idea.
