1.)If i wanna take a long exposure picture. lets say 20 minutes. A friend of my mine suggest me take a 30 second exposure and stack it?
What do they mean by stack it and how do i do it?
He also recommend me to use the star trail stacking software.
2.) how do i set the exposure or shutter speed for long exposure pictures for the sony NEX-5 camera?
thanks
