Need some help here with night potrait shots with background scenary. What i would like to achieve is e.g. there is a very nice background with lightings etc, but the area the person standing is quite dark, how do i illum the person and at the same time the background lightings and scenary will also be captured?
Do i need to use a tripod and do slightly long exposure, if so what are the recommended shutter speed? since i want the background i suppose i need small aperture at least 8 or 11?
My limitation is i am still using pop-up flash, would getting a pop-up flash diffuser help by not overexposing the person standing there?
