[QUOTE="Sda36, post: 272589, member: 17701"] More like 450.00 saved. It gives you the ability to basically do a digital try-in and verify. I started down this path many years ago with ClearMatch, this is far more concise. As we should all know, we can make 4 mistakes in color before only 1 in value. This methodology enables us to accurately measure L = Luminessence of an object, B = amount of Red in same, B = amount of Yellow. Since dental shades register in the yellow- red color space it's a matter of adjusting those values by those adding pigments to match the desired LAB values. You can photograph your actual porcelain shade fired samples ie A1-D4 or 0M1-5M1 and read your bottles actual LAB #'s. Shade guides vary significantly by each guide, our powders also by the bottle. As Dr. Jack Preston once noted, " There's more color control in Kraft Cheese than color control in dentistry." This methodology takes human perspective out and gives you a reproducible target #. Hope this helps, it has helped me understand a lot more of what I thought I already knew[emoji6] [URL]https://www.emulation.me/products/white_balance-gray-reference-card-for-dental-photography[/URL] Sent from my LG-H873 using Tapatalk [/QUOTE]
