Custom shades to succeed, the laboratory and dental office have to use the same camera setting to achieve the best results. Here are the settings I use in my lab and needs to be duplicated in the dental office.
Camera equipment: Digital SLR with ring flash or twin flash.
Polar Eyes &White balance card (photomed.com)
(White balance card has to be in all photo's. Half circle towards incisal edge.)
Camera Setting : Manual mode-F22 - Shutter 125 - Iso 100/200
Flash Setting: Polar Eyes- both Ring and Twin Flash -Manual 1/1
Regular picture: Manual setting Twin Flash 1/1
Regular Picture: Manual setting Ring flash :1/4 to 1/8
Regular ETTL Picture - twin flash 1/16
Ring flash needs to play around
The White Balance Card has a LAB number of L-79, A-0, B-0. We want all the pictures to to be slightly brighter than this.
All Photo's have to be in RAW format NO JPG
Camera Batteries need to be fresh to take the pictures. A good indicator if you need to replace the batteries is how long the flash takes to charge ( red light).
