[QUOTE="Jorge, post: 36304, member: 197"] Some settings I learned in a course, views as for the AACD I adapted the distances for an APS-C sensor camera so the magnification remains as intended AV and 1/200 exposure (via Custom function) or M and manual 1/200 Manual flash at 1/4 power (eg. MR-14EX) ISO 200 Obejtive: Canon 100mm F/2.8 macro on an APS-C size sensor camera All landscape orientation White balance: do not remember, but sure not AWB, at least use "flash" No tripod needed because with F/20 and 1/200 flash light is much greater than office light No AF, manual focusing (back and forward the camera, lens manual focused at desired distance) Aperture: F/6.3 for full head portrait (magnification 1:10, working distance 5 feet) F/20 for full smile (mag. 1:2, work. dist. 31cm) F/18 for full arch occlusal view (mag 1:2, work. dist. 31cm, not F/20 because of mirror) F/29 for some teeth (mag. 1:1, work dist. 17cm) With manual settings darker objects show darker. With ETTL tend to 18% reflective, if more or less background is included exposure can change. For lab photos you can begin testing yout gear with this settings for those magnification ratios, and then write down your preferences. Any comments welcomed. Regards [/QUOTE]
