I\'ll just keep believing that a ball thrown straight and bounced will keep going in the straight direction is was bounced ... (sans gravity, other outside force, etc.).
AI=AR
If I bounce 1 ball (at the appropriate angle) toward you, then you\'ll receive 1 ball.
If I bounce 3 balls (at the appropriate angle) toward you, then you\'ll receive 3 balls.
If I bounce 20 balls (at the appropriate angle) toward you, then you\'ll receive 20 balls.
If I throw 20 balls in 20 different directions (ISL) ... some of those balls may bounce toward you if they are the are the ones going in the same direction as those indicated above.
If I stand 100 feet away from my bounce target when I throw twenty balls in 20 different directions ... not very many are going to land on the target area I need to hit in order for them to bounce to you.
If I stand 1 foot away from my bounce target when I through twenty balls in 20 different directions, more of those balls will hit the target area necessary to bounce them to you.
So, when we move our source closer to our object that will be reflecting the photons ... THAT is when the the illuminance (volume per area) is determined. The reflected energy (sans absorption, refraction, etc.) continues iaw AI=AR in the amount and color accordingly.
ISL is like (akin to) shooting a shotgun, reflection is like some of those pellets ricocheting off the sign that\'ll put your eye out kid. Stand far from the sign and only a few get reflected back at you. Stand close to the sign, and you\'ll get a whole bunch coming back because more hit the sign (before they got spread too wide by ISL). The volume (small or large) that reflects off the sign will still travel iaw AI=AR.
