What are your setting for let`s say parties where there is less light, like a venue or a nightclub??
usually go for bigger aperture when its dark. Some depth of field is lost this way, unfortunately. All really depends on the film Im using or if Im worried about camera shake. There are many settings.
If Im going out at night with my Diana (without many options there) I use higher ISO film, an the cloudy option or Bulb settings if I have a place to steady my camera......
Flash is always a good idea, especially with some color gels on it - funky
