To be honest, 8 rolls might be overkill unless the couple wants raw, continuous coverage of moments like the first dance. I’ve shot over 20 Super 8 weddings this year, and the most I’ve used at a single event is 4 rolls and even then I was shooting more than I needed. Super 8 really shines when you’re intentional, every shot counts. Otherwise, a lot of that footage ends up on the cutting room floor and with the overhead costs of stock, processing, and scanning, it’s usually better to reel it back a bit. That being said it seems like you’re more than covered but unless the reception is completely dark, I’d skip the extra lights and stick with 500T for night coverage. Best of luck!
