Step 1: Hold the mobile phone.
In general, the front camera of a mobile phone will have a beauty function, and the front camera will flip and image, which will affect the teacher's judgment. So in order to be accurate, everyone will use the rear camera in the future, and everyone will use the rear camera. (Say the important things three times)
? Using the phone's rear camera means pointing the back of the phone at your tongue and shooting it with the help of a mirror or someone else.
If the teacher misjudges the tongue because the front camera is used to make the tongue have color difference or the left and right directions are wrong, all the consequences will be borne by the patient himself.
? The posture of holding the mobile phone is as shown above. Hold the mobile phone with your thumb and middle finger, hold the mobile phone with your little finger and ring finger, and empty your index finger. And ensure that the index finger can successfully press the shutter of the above posture before shooting.
The second step is to shoot formally.
When shooting, take a mirror, aim the camera at your tongue and aim the monitor at the mirror. (Note: The function of the mirror is to let yourself see whether your camera is aimed at the screen, and at the same time let yourself see where the shutter button of the mobile phone is, so that you can press the shutter button conveniently. )
As shown in the above figure, when we see the tongue phase in place on the screen of the mobile phone, press the shutter button, and the standardized tongue phase is completed.
Precautions:
? 1, put yourself in front of the light source when shooting to avoid the tongue being too dark. When shooting, you should see your mobile phone display in the mirror and clearly show your tongue and throat. But remember not to face the strong light, lest the contrast is too strong and the tongue surface is too bright, but you can't see inside. I usually shoot at the north window, which is bright enough and not too bright at the same time. )
2. Open your mouth as wide as possible, relax as much as possible and stick out your tongue.
3. Shooting should be done at the same time and place (or in the same direction) as far as possible, so as to avoid the excessive deviation of time and place, which will lead to the excessive gap of tongue color and thus affect the relative proportion of the front and rear tongues.
4. Be careful not to shake your hands when shooting, so as not to blur the photos.
5. You can check whether the tongue is blurred or missing after shooting. At the same time, you can check whether the color difference is obvious when looking in the mirror and taking pictures by yourself. If there is obvious color difference, you can take another picture in a different position until the color difference between the tongue and the mobile phone photo is basically the same when you look in the mirror.
Acknowledgement: The teacher has a good medical skill. Although many unclear photos can show clues, they obviously consume more energy and time. Therefore, as patients, we should sympathize with teachers and provide better patients for teachers to see. At the same time, I thank the teachers for their hard work and inculcation.
