mondoxjake: render resolution.. it reallity at it really means is you're increasing the size of the image.. (it's really only usefull for prinitng).. becuase when u look at somethimg on your monitor.. you are still limited by your monitors screen resolution.. in most cases 72dpi.. so what u really want to do is get as many dots in yoiuyr image as possible... what i do.. just before i render .. i switch my monitor to 1600 x 900.. speed to render: default render settings for hdri.. low qual ; 3 minutes mediam qual: 10-20 min high qual: 20 min to 10 hours!
