This is the crux of the problem Glowing metals like tungsten have a full spectrum. The line of the colors included is an even line.
Fluorescents and LEDS on the other hand are efficient in part because they output only certain colors. You can create the appearance of full specturm for say a video monitor score board, but whether or not you can match the spectrum of VC papers is another matter. VC papers are designed with yellow and mageneta filters based on tungsten light sources. If LEDs can match this then you're correct they would be the most controllable and precise. If they miss the correct parts of the spectrum they they will require a workaround that would make them not worth replacing very even quartz tungsten bulbs. ---William Nettles [EMAIL PROTECTED] Nettles Photo / Imaging Site http://www.wgn.net/~nettles Find out what's happening in Echo Park: [EMAIL PROTECTED] > From: [EMAIL PROTECTED] > Reply-To: [EMAIL PROTECTED] > Date: Tue, 5 Feb 2002 12:07:08 -0700 > To: [EMAIL PROTECTED] > Subject: Cameramakers digest, Vol 1 #330 - 11 msgs > > The whole idea of using a panel made up of arrays of red, green and > blue LEDs is that the output colour temperature can be smoothly adjusted > to anything you want or need without problem.
