filmscanners: Nikon Scan DOES Vary LED Brightness

2001-11-26 Thread Jawed Ashraf
Well, in disbelief, I have just done a test. With Nikon Scan 3.1.1 running stand-alone. Nikon Scan has four sliders for Analog Gain: Master, Red, Green and Blue. They work additively, i.e. Red brightness equals Master + Red. In my test I used a slide that I have lying around (i.e. I didn't use
