At this time, make sure that you are standing in one place, and keep the digital camera close to your body when you rotate your body to take each photo. In addition, don't move from the original shooting position when shooting, try to stand firm. The purpose of this is to imitate the environment with a tripod and make the camera rotate around a point as smoothly as possible. 2. Shoot vertically, not horizontally. Take more photos in the same place, the edge deformation of the photos will be less, and the panoramic photos will look better. 3. The white balance of the camera is best set to cloudy day. If it is set to automatic, the white balance of each photo may change, which is very bad. 4. Press the shutter half way, set the exposure light, then observe the viewfinder and record the aperture value and shutter speed. Now set the camera to m and adjust it to the value just recorded. In the future, the exposure in PS will drive you crazy. If you focus on the first picture, then turn off the focus in the future, so that the camera doesn't have to refocus every picture, otherwise it will be very bad. 6. Before taking the first photo, you'd better take a photo with your finger in front of the camera, because what you want to take is not one photo, but several or countless photos. Unless you are very familiar with this scene, you won't know where to start shooting. After taking the last photo, repeat this operation in the same way. 7. Each photo overlaps by 20%-25%. Make sure that the first photo has 1/4/ in the second photo, and each photo overlaps by at least 20%. Then it is very important for PS to be easily spliced.
