Subject: [roots] Cool deep photo

Anyone that has tried taking photos through a scope knows how tough it is 
to get enough light into a canal for a decent photo.  After removing the post, 
I measured the gp you see in this photo and it was 13mm down. The secret is a 
brilliant ring flash (Canon MR EX-14) and a varifield, a device that narrows 
the scope light beam to a small circle allowing for more intense light deeper.  
I looked into finding this on ebay. Global doesn't make them anymore.

Wow! Looks great Mark. I wish I had had such a thing for the furcation 21 mm down in a lower bicuspid I did tonight. Only one picture of about 10 turned out half way decent - Winfried Fantastic pictures. What camera are you using and please more details on the varifield ( brand, type, etc). - Sergio. Sergio, Canon 20D. Unfortunately the Varifield isn't available any longer. It was a Global item and they stopped producing it a number of years ago - Mark Got to get me a varifield. Like I need to stack more parts between the oculars and the patient - gary
