Title: Head scan, lightning and best position.
Post by: Tyler J on January 25, 2014, 06:38:27 PM
Hi,

Recently I did some experimentation with a Coolpix L27, taking 21 pictures, and a silicone mask stuffed with t-shirts.
Contrary to my belief I got some very good result :

Moving to live humans I plan to get 30 of them however I do not have a lightning system yet.
Since I have little to no knowledge of photography I don't want to buy stuff that won't be of use.

My main idea is to use 30 3W warm white LED, one on each camera (light intensity will be adjustable).
warm white can be corrected with the white balance and it's cheaper than natural light led.
but since I'm making a sphere around the head each camera will "see" 15 leds, woudn't this make a bad pictures?

How could I evenly light a human head?

also would it help to make a 15 stereo pair camera sphere rather than a 30 camera sphere.
Thanks.
