Hi guys,i'm new on here and i need an advice on which settings should i use for.... I'm planning to go for a quick camping with my friends,in the "woods",but it's not actually complete woods,covered with trees etc...There are still a few houses nearby. So i'd like to take a night photo of us,of course with (almost) complete dark,a bit of light polution from the houses nearby,but not sure which settings should i use for that type. I have (as mentioned in title) Nikon D5100,with 18-55 mm f/3.5-5.6 VR lens.Would max apperture (3.5),and let's say shutter speed of 1/15,1/30 do the job? Could you guys give me an advice,and should i use the flash? Edit:And yes,i'll be using a tripod,i forgot to mention that.
