Tonight I am shooting backyard fireworks as a warmup to the big show in 2 weeks and I want to get all the info down. f8-11 5 seconds+ ISO 400 Those settings sound right or should I use a larger aperture because these are just backyard fireworks and probably no where near as bright as the big ones at WDW. Also I'm not sure about the ISO settings, I dont want to blow out the photos. I'm using the Kx and processing in LR3.2 so noise isnt an issue either I dont think. I'm going to use my manual 28mm I think.
