good close up photos

Hi there,
I have got the following equipment:
Canon EOS 30D
Canon macro lens EF 100 f 2.8
macro ring lite MR 14 EX

Does any body have any suggestions for appropriate settings to enable me to take fotos of smiling teeth.I'm a dentist and I want to take fotos of my work to make a portfolio.
What i seem to be having trouble with is depth of field, and getting every thing in focus. I use the all automatic setting on the camera. I tried with the macro setting on the camera, and the results were not that good. I tried to increase the depth of field, by manually controlling the aperture, but the shutter speed was so long that the fotos were too shaky.
Has anyone got any suggestions.

Put your camera in manual mode, set you aperature at around f16 and shutter speed of around 1/125s, then set you macro ring lite flash in ettl mode and this would give you good results.

Hi heffsarmy,
just spent 5 seconds doing this and results look promising.
Thanks for the reply

What I did with my flash ring is set the custom function to 3-1 (I believe) which is a set 1/200 speed with the flash and set it at f22. I do mostly intraoral shots since I am a dentist but that works the best for me....

not staying in this thread Dentist Scare me im off
ps like my

One thing. When you're at that small of an aperture, dust on your lens/sensor is gonna show up. Make sure your sensor is clean, or there'll be little black spots on their teeth!

I agree with a previous poster about using the camera in manual, but one recommendation I would make is to use a tripod if at all possible along with a remote shutter release or a timer. With macro photography the subject magnification is so high that the slightest camera shake will result in motion blur unless you have a significantly fast shutter speed.

Don't you think the person with the teeth that are being shot will shake . If it was me you could use a tripod but woud never get a shot without movement.

Some personal views on Sensor cleaning.

Dear all,
thanx for your help. I'm now getting good pictures. In fact they are so good I can see mistakes in my work, so now I'll have to work harder to achieve good results.
tripods arn't really doable in the clinic, not with all the chair and drills and all that lot around.
Still thanks again to you all

Advice to all who are not dentists, all you haveto do is brush those toothypegs, and you will never have a problem at the dentist

Since the ring flash will provide far more illumination than any ambient light and since the flash duration is very quick, there won't be any motion blur to worry about unless the patient is trying to run away.
