How to light the ceiling of your mouth

Taking pictures on the oral ceiling requires you to make special efforts in the oral industry. You must persevere, concentrate and wait patiently to get to the ceiling.

What is the use of oral photography for a dentist?

1. record: it is helpful to collect clinical data, medical legal basis and publish articles.

2. Education: including self-education, patient education and teaching materials, so that more peers can learn and make progress, just like now.

If you want to do a good job, you must sharpen your tools first. Let's take a look at the tools needed for oral photography, mainly including: camera body (digital SLR camera), macro lens (100 or 105mm), external flash (ring or point flash), oral photography mirror, retractor and background.

First of all, the lens, from the following picture, we can easily distinguish the difference of photo quality under different lenses.

At present, the camera for oral photography is Nikon D90. I want to choose a macro: 60 MMF/2.8D；; ; 2.60 MMF/2.8 ged； Santenglong 90 mm

It is better to have a larger focal length, and the lens should not be so close to the patient's mouth, which will not affect the doctor's operation.

At present, panorama camera, which has the largest domestic share, is a Korean friend, and the current price has dropped to more than 20 W.

Choose panorama camera should pay attention to two points:

1, the imaging effect is good and clear. Domestic imaging effect is generally not as good as foreign products.

2, reliable quality. At present, friends who use EasyTour haven't had any problems.

2. Perfect after-sales. Imagine that such a large panoramic camera can't move when it is installed. In case of problems, maintenance personnel need to be in place in time. The panic button that used to work in the panoramic machine was accidentally touched, causing the panoramic machine to be paralyzed. I made a phone call and the maintenance staff arrived the next morning.

So buy a panoramic camera, and then consider the later maintenance and upgrade. For example, some panoramic models can be upgraded to CBCT.

SLR cameras used in stomatology mainly take pictures of teeth in the mouth. Please recommend the camera lens flash 1 10,000 or so.

Which is better, oral photography Canon 70d or Nikon d7 100?

Canon 70D is recommended for portrait photography. Reason:

1, Canon's strength is chips. The color reproduction of Canon D chip is very good, with high sensitivity and little noise. Compared with Nikon, Canon often wins the same camera sensitivity, 5D3 is better than D800, 6D is better than D6 10, and 70D is better than D7 100. However, Canon's shortcomings are that the sensor technology is relatively backward and the tolerance is relatively poor, which is manifested in the fact that when the scene with large light ratio is imaged, the highlights are easy to overflow (dead white);

2. Nikon's strength is the sensor. Nikon uses a tactile sensor developed by Sony. After Nikon's adjustment, the color depth and dynamic range are much better than Canon's and beyond Sony itself. Nikon sensor's tolerance is the best, no one, and the imaging details are the richest. But Nikon's disadvantage is that the color reproduction of E film is poor and the color tends to yellow (commonly known as Nikon yellow). Although the technology is very powerful in the later stage, it can even subvert the color, but Nikon is not as good as Canon in the original color reproduction ability;

3. The landlord mainly takes portrait photography, and the strength of 70D color reproduction can be fully reflected. Because portraits have higher requirements for color reproduction and lower requirements for tolerance; On the contrary, landscape photography requires higher tolerance and lower color reproduction, so Nikon is more suitable for landscape photography;

4. The lens group support of Canon and Nikon is basically the same, because the portrait color of 70D is better (Canon color is best modulated by RAW and DPP, which is better than the modulation effect of third-party software such as Freescale, CS6-ACR or LR), and the unique full-pixel dual-core autofocus function of Canon equipped with 70D is powerful.

It is incorrect to say that Nikon can shoot directly without PS. Serious photography is an integral part of photography. Without it, there would be no photography (internal revision is also a kind of post-photography). As for the shooting of the family's trip, it is more suitable to use portable cameras such as Fuji X 100, Canon G 1X, Nikon CA and Sony RX 100. , no SLR.

6. In terms of camera performance, D7 100 is more powerful than 70D. D7 100 If the landlord has plans to study photography and later study, it is recommended. Because when the later technology reaches a certain achievement, you can play with color, but the tolerance is physical and cannot be changed later.

7. In fact, Pentax K3 is better, but the lens support is not as good as Canon Nikon. If you don't play with the camera, Pentax K3 is more suitable.

I hope it will help the landlord.
