<p>[QUOTE=&quot;messydesk, post: 2877562, member: 1765&quot;]This is a really confusing chart from the award-winning article and best-selling book.&nbsp; A bare filament bulb and a halogen bulb are both rather intense point-source lights, yet they have opposite effects on perception of grade in the article.&nbsp; Likewise if you compare fluorescent bulbs (of the time) to a diffused floodlight, both of which are quite soft.&nbsp; The use of a single light source that is small and bright (but not too bright, like the sun) is going to get you the best results if you are consistent in using it.[/QUOTE]</p><p><br /></p>
