Light portrait photography shutter

Hehe, according to your request, there are only two ways. One is to use a large aperture lens to improve the shutter speed, and the other is to use a tripod. I don't know if your camera is a SLR. Can you change the lens? From your description, I guess it's not a SLR, because: first, the ISO of SLR is slightly higher, and second, the white balance of SLR is more accurate, so there will be no unnatural problems. According to my experience in using telephoto consumer cameras for four years before I entered the SLR, I will give you some suggestions: 1, ISO can be a little higher, is 400 available? If 400 is not available, 200 is always available. 2, or turn on the flash, I used a telephoto machine before, and I didn't think it was unnatural to turn on the flash. 3. The most important thing is, if it is unnatural to turn on the flash automatically, you must use M file, because after turning on the flash automatically, the shutter speed is high, about 60, which leads to bright people and dark background; Slow synchronization, the shutter is around 15, which is too slow, leading to jitter. So you need M gear, use the maximum aperture, and lower the shutter speed to about 30, so that you can hold it without shaking, as slowly as possible. This is my own valuable experience, which most people don't know. 4. If you have a tripod, you can flash slowly and synchronize slowly. 5. Does the camera have optical image stabilization? Open it if you have it. Forget electronic image stabilization, it's a trick function.
