I am struggling to take occlusal photos of cavity preps with a rubber dam in place.  Do you have any tips for me..there just does not seem to be any space, and I seem to be getting shadows in places??

A  Firstly if you are getting shadowing, just check both sides of the flash are firing…obviously don’t look straight into the flash. If they are both working I would suggest that you change your magnification so that you are a bit further back, you will need to zoom the image on playback, but being a little further back will give you a broader spread of light, other thing to try is rotate the ringflash 90 degrees, this will give a slightly different angle of light on the subject.


Q Thanks again for that informative session. I also took a quick look at some prices for Nikon D5300 and D7000. From what I could find the d7000 is £50-100 more expensive. Is there a palpable difference between them?

2 main differences between the D7000 and D5300
D7000 has twin SD card slots so you can store jpgs on one and RAW on the other but is an older camera than the new 5300
D5300 has wifi built in, but you can wifi enable the D7000 with an eye-fi card

 So the D7000 is a great enthusiasts camera, but the D5300 is the latest model and cheaper so for your dental photography it might be a better buy, but I like the twin card function for simplifying RAW storage.

I am currently participating in your future learn improving your photography course. I was wondering if I could ask you a quick question regarding cameras?
I currently have a sony NEX-5N. I have struggled to find a ring flash that would fit a sony lens and consequently have not yet brought a sony macro lens. Is there a way of fitting an adaptor and buying a lens from another brand of camera and an associated ring flash?

Or would it be easier/cheaper for me to start fresh and invest in a new camera and keep the sony for holidays and personal use?

The NEX 5N is a Compact System Camera and compatible ringflash. This type of camera can be used for your dental photography, but is not ideal. So I personally would go for a Canon or Nikon DSLR for your dental Photography.

 I was looking for your advice regarding a camera. I was wondering what you thought of the Canon EOS M and whether or not this is acceptable for use in dental photography? 

The Nikon M is a CSC (compact system camera) and is not a type I recommend for clinical work…main problem is accurate focus and continuity of magnification, also you may find accessories for it in terms of lens and ringflash as expensive as a DSLR…if you wanted something smaller you can use for both personal and clinical then have a look at the Canon 100D…
