    Över-/underexponering

    In a digital camera i would alway slightly underexpose. Think in this way: each bucket (each photo site, or currently called pixel) has a limited size. That means that can accommodate inside a certain amount of fotons. When the bucket is full, no matter how may fotons continue to reach the...

    Slits kameran när man filmar?

Don't get me wrong, i love them and i use a lot for for filming but, even using enhancements like magic lantern, the dslrs are very limited in many ways. Just to name a few, the dslrs...
