Hey all, Sorry I been away a while but life has been hectic! I have a problem. Im shooting a band at a gig tomorrow night and Im not sure 1) If I can use flash 2) what iso film to use. My tutor said I could use iso 400 and clock it up to 800 and under expose and lengthen the development process?! Ive never heard of this. Has anyone done this? How does it come out? I really have no idea how bright the stage is going to be lit, I really have no idea and I think flash would ruin the shots. What does everyone think? Lemme know asap.
