<p>Dimming and brightening functions. </p>
<p>The eye does not respond in a linear way to light. High speed PWM'd LEDs at 50% duty cycle appear far brighter then the 'half as bright' you might expect.</p>
<p>If you want your midpoint brightness leve (128) to appear half as bright as 'full' brightness (255), you have to apply a 'dimming function'. </p>
