<p>[QUOTE="mdjensen9, post: 2169836, member: 73784"]I'd like to add as a lighting specialist. The color of an object as illuminated by a light source is directly related to the CRI ( color rendering index). Incandescent light sources all have a 100 CRI. The reflected color you see is the color it is. CFL bulbs have a less than desirable CRI, typically around mid 70 - upper 80's. All fluorescent bulbs have a 3 number listed i.e 741, 750, 835 etc. The first number is the CRI, the second is the color temperature from lowest <u>27</u>00 (incandescent warm) to <u>70</u>00 very white with some blue ( color of sky at high noon on a cloudless day). LED can also be a good source, but very few with a CRI over 90 so far. </p><p>With all that useless info, the higher the CRI to 100 and adjusting the camera settings will give you the best chance at the true color.</p><p>Good luck[/QUOTE]</p><p><br /></p>
