With the eLAB system you can transform your digital camera into an easy to use shade matching system by following this photographic protocol

Image

1. Watch out for dehydration! After exposure to air for more than 2 Min, dehydration sets in and shade images need to be taken some other day.

Image

2. Turn off E-TTL when using polar_eyes! Use the manual mode to set the intensity to 1/1 or 1/2. The image quality should be set to RAW (not JPEG).

Image

3. Always use retractors and make sure they are held firmly by the end of their handles, pulled up and back towards the ears. Matte black retractors are ideal.

Image

4. The optical axis of the camera should be perpendicular to the white_balance card.

Image

5. Make sure the white_balance card is positioned in the middle of the frame and that the two lower crop marks are fully captured.

Image

6. Take one cross-polarized image with polar_eyes and with the white_balance card placed slightly below the incisal edges.

 

Image

7. For reflected images without polar_eyes, the flash intensity needs to be lowered to 1/4 in the manual mode or simply switch to E-TTL.

Image

8. Take one reflected image for your dental lab to provide useful information about the surface texture and gloss.

Image

9. If the object of interest is a lateral or canine instead, the position of the white_balance card needs to be adjusted accordingly.

 

Image

10. When taking the polarized picture make sure that the two lower crop marks are captured here as well.
