My brother recently bought the Nikon D5100 DSLR. Everything seems to be fine with it, except taking photos indoors (even with the light on and curtains wide open in the day) seems to be a problem unless you set the ISO to around 800 and have maximum aperture width and a slow shutter speed. OR alternatively just use the flash with everything else on whatever settings you want.
An alternate message if you adjust the settings to cope with low-light conditions is 'lighting is poor, flash recommended'. Now this environment in a well-lit room doesn't seem to me to be poorly-lit.Is this normal for a DSLR to cope with lighting like this indoors? He hasn't told me if he encounters a similar problem with outdoor shots yet, however. We're quite new to DSLRS (we have read the manuals etc.though).
