<p>[QUOTE=&quot;SuperDave, post: 2925540, member: 1892&quot;]White isn&#039;t always &quot;white.&quot; The definition of &quot;white&quot; varies, and the resource you use called &quot;white&quot; may or may not be more &quot;bluish&quot; than the next. On the Kelvin scale, by which color temperature is measured, &quot;white&quot; isn&#039;t at one end as it is in RGB (&quot;black&quot; is the total absence of light, &quot;white&quot; is all three colors of light equally and 100%, and every color lies between). On the Kelvin scale once you go past white you proceed into bluish tones, and some hint of blue is often added to what purports to be &quot;white&quot; in order to make the result appear subjectively &quot;brighter&quot; to the observer. &quot;18% grey&quot; is an absolute on any scale, and any shade of grey is easier on the camera.</p><p><br /></p><p>All that aside, I do White Balance using pure white - a stack of whatever printer paper I have laying around - and do not worry about the minor difference between the paper color and RGB 255, 255, 255. It gets me close enough to not notice the difference on a monitor which displays color rather capably, and gives me a baseline for exposure correction (I try to get the coin not washed out while still keeping the &quot;white&quot; visible on the screen as &quot;white&quot; as possible). In [USER=40017]@PaddyB[/USER]&#039;s pics above, the &quot;white&quot; background is kinda grey, and I attempt to make it whiter than that.</p><p><br /></p><p>Then I shoot the images you see on a black background anyways, because that&#039;s how I like it. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
