They work just the same with either kind of capture. It's an optical process so the light rays getting to the film or sensor are just the same no matter what recording medium they find. > There's less time required in post processing than with green screen & > getting the lighting setup right is a lot less fussy than with green screen > - at least based on my experience shooting green screen it is. > You'd be assuming, then, that front projection is easy to work with, compared to green screen shooting. While green screen has its difficulties, I'd take it any day over front projection. Front projection is an extremely inflexible setup. The camera and projector are locked together and in turn are fixed in relationship to the background screen. The least misalignment gives a cartoonish dark outline to the subject. Imagine shooting portraits under those conditions. The whole operation is extremely programmed and rather like cranking out sausages from a sausage machine. Change the background scene? Sure, that's the Raison d'être of front projection. Change the lighting? A little, but be very careful. Change the camera position in any way, no matter how little? Forget about it. Not much room for spontaneity there, then. Might as well get a job assembling iPhones in a Chinese factory. Not much good for difficult subjects like wriggly children and animals and such. And you'd better keep a good stock of adjustable stools in your studio to cater for varying sized sitters in group shots, and get accustomed to constant re-adjustment of them. Because remember. you can't move or tilt the camera to compensate for common variables in everyday portraiture. Have fun! Anyway, what problems did green screen give you? If light and shadows from the subject lighting contaminated the background, then your studio was too short and the background too close. If you forced the lights to do double-duty, lighting up the subject AND the background, then that's a problem too, unless the lights have huge coverage. It's best to have dedicated background lights. If you're shooting outdoors then simply keep the green screen well away from the subject's shadows. Follow this advice and you'd get a good even green, easy to select in post-editing. regards, Anthony "Of what use is lens and light to those who lack in mind and sight" (Anon) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
