>>4398655there's a few ways you could do this
1. the RIGHT way is generally you need 3x lights, 2x for the backdrop (flagged using V-flats) and 1x for the subject, up high. (picrel)
1x paper roll and a backdrop stand if you don't want to build a cyclorama (which, face it, unless you own a studio, nobody needs)
2. you could in theory get away with 1x main and 1x for the backdrop, just have enough distance to control any stray bounce from the backdrop
3. personally, I used a 1200w/s strobe on a cyclorama in a massive octa (2.5m IIRC) and that had a similar effect, just needed to even out the background and clean up any defects as it wasn't blown out
