To photograph the oral cavity on the canopy requires you to do special efforts in the dental industry, do things consistently, be dedicated and also have the patience to be able to go to the canopy.
What are the uses of oral photography for a dentist?
1. Record: helps in the collection of clinical information, medical-legal basis and publication of articles, etc..
2. Education: including self-education, patient education and as teaching material for more colleagues to learn and progress, like now.
To do a good job, we will look at the tools needed for dental photography, including: camera body (digital SLR camera), macro lens (100 or 105mm), external flash (ring or spot flash), dental photography mirror, pull hooks and background.
First of all, let's talk about the lenses, from the following pictures it is not difficult to distinguish the difference in photo quality between different lenses.
The camera used for oral photography is the Nikon D90 want to choose a macro: a 60mm f/2.8D; 60mm f/2.8GED; three Tenglong 90mm
The focal length of the best,, the lens from the patient's oral cavity does not need to be so close to the doctor does not affect the operation.
Currently the largest panoramic machine in China is the South Korean Yiyou, the current price has dropped to more than 20W.
Elect panoramic machine to focus on 2 points:
1, the imaging effect is good, clear. Domestic imaging effect PuPo is not as good as foreign goods.
2, reliable quality. At present, friends with Yiyou, have not had any problems.
2, after-sales perfect. Imagine such a large panoramic machine, installed on the can not be moved, in case of a problem, the need for maintenance personnel in place in a timely manner. Once the unit panoramic machine emergency button was mistakenly touched, resulting in panoramic machine paralyzed, made a phone call, maintenance personnel arrived the next morning.
So when you buy a panoramic camera, you need to think about maintenance and upgrades later. Like some panoramic models can be upgraded to CBCT

Oral photography Canon 70d and Nikon d7100 which is good
Portrait photography recommended Canon 70D. reasons:
1, Canon's strong point is the chip. The Canon D chip has very good color reproduction and less noise in high sensitivity. Canon compared to Nikon, the same level of camera high sensitivity often wins, 5D3 is stronger than the D800, 6D is stronger than the D610, 70D is also better than the D7100. But Canon's shortcomings are relatively backward sensor technology, tolerance is relatively poor, manifested in large light ratio scene imaging, highlights are easy to overflow (dead white);
2, Nikon's strength is the sensor. Nikon uses the Sony developed touch sensor, after Nikon tuning, color depth and dynamic range is much better than Canon, also beyond the Sony itself, Nikon sensor tolerance is the best, no one, imaging is the most rich in detail. However, Nikon's shortcomings is that the E-chip's color reproduction is relatively poor, and the colors have a tendency to be yellowish (commonly known as Nikon yellow). Although the current post-production technology is very powerful, and can even subvert the color, but on the native color reproduction ability, Nikon is really not as good as Canon;
3, the owner of the portrait photography, 70D color reproduction of the strong points can be fully reflected. Because the portrait of the color reproduction requirements are relatively high, the tolerance requirements are relatively low; on the contrary, landscape photography because of the tolerance requirements are relatively high, the color reproduction requirements are relatively low, so the landscape shooting Nikon is more suitable;
4, Canon and Nikon's lens group support is basically the same, due to the 70D's portraits of the color is better (Canon color is the best to use the RAW plus DPP modulation than Third-party software such as Fei Si, CS6-ACR or LR modulation are better), coupled with 70D equipped with Canon's unique all-pixel dual-core autofocus, capture powerful.
5, Nikon does not need to PS directly out of the film is incorrect. Serious photography, post is an integral part of photography, there is no photography without post (in-camera correction is also a kind of post). As for family to here photography, it is more suitable to use portable camera such as Fuji X100, Canon G1X, Nikon CA, Sony RX100, etc., no need to use DSLR.
6, in terms of camera performance, the D7100 is more powerful than the 70D. If the owner has the intention to learn photography and learn post, then it is recommended that the D7100. because when the post technology has reached a certain achievement, you can play with the color, but the tolerance is physical, and the post can not be changed.
7, in fact, Pentax K3 is better, just the lens support is not as good as Canon Nikon, if you do not play with the lens, (one machine, one realm or one machine, two mirrors), Pentax K3 is more appropriate.
I hope to help the owner.
