If I remember my optics subject, shiny opaque objects do not absorb light, they reflect them. (Reflection though, is not absolute and may or may not involve all the colors of the visible light spectrum R O Y G B I V.) Aluminum is one shiny opaque object, thus, it reflects light. Dark opaque objects are the one that absorbs light.

Now, how much light is reflected towards your set up is another matter..

This will depend on number of factors. I'll mention a few..

1. Angle of reflection - the angle of incidence is equal to the angle of reflection
a. shape of your reflector. If using rounded reflector, make sure that your focal point is towards your set up. (imagine a flashlight).
b. roughness of surface. Any bump on the reflector surface even how microscopic it is, will reflect light away from your set-up..

2. Impurities at reflector surface - The aluminum maybe opaque but how about the presence of other materials on its surface. Example, paints, oil films, dusts, some of these will cause light to be absorbed, refracted or reflected outward which in turn will reduce the amount of light reflected back to your set up.

3. Color of the surface -make sure that the shiny object reflects all the light spectrum. (white/silver and shiny imo makita). If lain color for example yellow, that means all the other colors were absorbed and only yellow is reflected.. if dark black, that means no color is reflected at all..

Daghan pa lain pero trivial na kaayo..

My two cents..

@gaevwa

thnx sa info! =)

@all

kinsai naai na bal an na pangpolish sa aluminum metals?

[swordfishh]

@smalltime
dude pag palit nalang ug reflector ayaw sa nang red horse kay dili bya jud na maka reflect sa light ang empty bottles sa red horse. nyahahaha peace

[swordfishh]

@smalltime
bitaw dude asa ka naka palit sa imo aluminum metal?
