? - Ok I need reschooling in this... I don't remember exactly what I wrote before to him (or who was asking:) ) but someone said to cross nichols with the lens on the camera and the polarized sheet on the light source before you shoot - the object being shot would not be between light sources.
my knowlege of crossed polarization comes from looking at thin sections of rock through a microscope where the crossed nichols (maybe spelling this wrong, memory is fading) create birefringence. MY idea that was perhaps not scientific was to put a polarizer on two light sources, then look through the camera at each with the polarizer on the camera and on the sources until it is totally blacked out.... the 45 degree angle of two light sources is often a good way to shoot a still object for minimizing reflections, yes? polarized glass at right angles to each other totally blocks out light (you didnt leave in what the guy who asked the question first and my original suggestion was - so maybe I'm just misunderstanding you) ann the easily confused Glen Berry wrote: >ann sanfedele wrote: > > > >>instead of using flashes, can you set up two light sources at 45 degree >>angles with polarizing sheets on them? >> >> >> >> >The angle for maximum glare reduction is 90 degrees.
