dental settings!

[maan]

Hi All


I'm a dental resident and brand new member in digital photography. I'm still learning digital terms. I bought the new 10D with the Canon 14 ex ringflash and 105 Sigma micro lens. I wanted help in having the best setting to achieve excellent intra oral photos.

Thank you.

Maan,

I have D30 and 1D and 100mm Canon lens, but you should get similar results. Put the 10D in manual mode.

For INTRAORAL:
I picked 1/60sec (fast enough to drink plenty of coffee and not exhibit blurry results with my pictures!) and F32 for most depth of field (from centrals to 2nd molars).

I set my ringflash to +1 1/3 (see 'powerpoint' below), which is an easy way to override the camera settings (see docs on ringflash).

You'll see magnificent color and the entire field in focus.

for EXTRAORAL: I place in "P" mode and take my photos with as much lumination in the room as possible to minimize red-eye. Kois will tell you to take extraoral with BLACK background to eliminate shadows which distract from your subject.

Here's where digital excels!
FINALLY, take all your pictures and import them into powerpoint, ALONG with the data generated (f stop, etc) and play your pictures back to see how different flash setting affect your results.

If more questions, please feel to contact me directly at mark@benavides.org

Warmest Regards,

hi maan,
i have a 10D with 100mm canon macro and a MT-24EX flash. for intra-oral shots the WB is set on AWB, the mode is set on M (lens auto-focus also on M), ISO on 100 (have also tried 400 and 800 to reduce flash in patient's eyes) shutter speed at 125 and f stop at 29 or 32 for best depth of field. i have been setting the flash exposure compensation at +2/3 and have been getting excellent results. the same settings are working fine for benchtop shots of models and porcelain work, as well. shooting in RAW has given me opportunities for making adjustments should they be necessary.
i found the MT-24EX macro light to be preferrable over my MT-14EX for all of my dental shots because it eliminates the eliptical highlights that tend to be distracting and unnatural in presentations.
hope it helps,
briant

Thanks all for your kind comments:)


I'm trying different settings with some cases. Maybe I'll post these settings with some of the photos and discuss it later here in this forum.

Again thanks all for your help.

Since you guys have managed to fill the knowledge gaps here, maybe you could have a look at the extracting the JPEG file discussion.

:D He, he, he, he, he...
