Good photography lies at the heart of absolutely every area of esthetic dentistry. The correct use of the clinical camera is an invaluable way for the practitioner not only to document what is being done in terms of pre-treatment and post-treatment photographs of cases, thereby maintaining excellent clinical records but also to improve patient education and enhance his or her self-education. dental photography, camera for dentist, dentist with a camera, teeth photography, dental photography techniques, intraoral photos, dental stock photos,
IMPORTANCE OF DENTAL PHOTOGRAPHY. Human memory is terribly short. So, patients easily forget what they looked like before they started treatment which sometimes puts the practitioner at substantial legal risk. • All practitioners learn by seeing clinical photographs in books and journals. Viewing their own patients in this same way frequently improves their dental abilities. • Increase the patient level of requested treatment & patient Communication. • It is an excellent supplement to traditional dental charting. • orthodontic photography, oral photography, intra and extra oral photos, protocols for mobile dental photography with auxiliary lighting, free dental photos, extraoral photography To be used in treatment planning. • Communication Dental technician. • Marketing.
CAMERA DEVELOPMENT FROM HUMAN EYE PHYSIOLOGY.
CORRELATION BETWEEN EYE AND CAMERA.
UNDERSTANDING EXPOSURE TRIANGLE • Understanding the three main elements of exposure & knowing how to adjust them will helps you to get the best out of your camera & to take great photographs. • They consist of: 1. ISO 2. Shutter Speed 3. Aperture.
ISO • The level of sensitivity of your camera to available light. • It is typically measured in numbers, a lower number representing lower sensitivity to available light, while higher numbers mean more sensitivity. • More sensitivity comes at the cost though, as the ISO increases, so does the grain/noise in the images. • Examples of ISO: 100, 200, 400, 800, 1600.
DIFFERENT ISO LEVEL.
SHUTTER SPEED • The length of time a camera shutter is open to expose light into the camera sensor. • Shutter speeds are typically measured in fractions of a second, when they are under a second. • Slow shutter speeds allow more light into the camera sensor and are used for low-light and night photography, while fast shutter speeds help to freeze motion. • Examples of shutter speeds: 1/15 (1/15th of a second), 1/30, 1/60, 1/125.

But, lowering shutter speed will make a hazy photo if the object or camera are not fixed!
WHAT IS THE SOLUTION IN CASE OF THAT? • Use a flash • Or increase iso sensitivity • Or fixe both camera by using tripod and the object • Or decrees focal ratio ( to be discussed).

Aperture • A hole within a lens, through which light travels into the camera body. • The larger the hole, the more light passes to the camera sensor. • Aperture also controls the depth of field.
