I love this:
Dine’s new Smart LED Ring Light properly illuminates the close up subject, turning your smart phone into a dental/medical camera. The LED Ring light provides full shadowless illumination inside the mouth for dental photography, inside the surgical cavity as well as providing accurate color and illumination for cosmetic/plastic surgery, dermatology and ophthalmology.
Two issues. First be cautious when using your smart phone for patient photos. Be sure the auto save to the cloud feature is turned off. iCloud and the others are not HIPAA compliant.
Second is the price. $349. You can practically buy a phone for that price. You can find snap on consumer “Selfie Lights” for less than $20. I know everything “dental” costs more and I am also sure the Dine light is better than the $20 version but is is 18 times better?
