wad do u mean by read meter?...i look from live view and judge from eyes...sometimes histogram to prevent from under expose...
i use iso 200-400 EV+1 to EV+2 and slower Shutter speed to 1/40 - 1/60...coz the whole room is not very well lit and for ur info i use slr-like, not dslr...pushing high iso to 1600 or more will have noise
...didnt intend to use flash as its no long candid
