How to set streamer shooting for Apple mobile phone?

The iPhone has no built-in scene shooting mode such as "Streamer Shutter", but it can be realized by third-party software. Such as procam5 or slow shutter. Let me introduce, procam5 is a comprehensive shooting software of IOS version, with powerful functions, which can be seen from its setting interface. Procam5 has a professional manual shooting mode, and the function of time-lapse photography is more powerful than that of mobile phone, as well as night scene mode and slow door shooting mode. You can take RAW photos directly. Procam5 has three slow gate modes, namely dynamic blur, light track and weak light. The principle of dynamic blur is the same as that of optical track, and the effect of slow gate is realized by superposition technology. Dynamic blur can play the role of drawing water surface, and can also blur the moving crowd in the scenic spot. Light rail is suitable for shooting the traffic flowing at night, and it can shoot the track of pulling out the lights. There is also a low light mode, which is suitable for taking still pictures in a dark environment. The shutter speeds of these three modes are 4 seconds, 8 seconds, 15 seconds, 30 seconds and B-gate respectively. When shooting with door B, you need to press the shutter twice, once at the beginning and once at the end, and the interval between them is the exposure time.

Slow shutter is a professional slow door shooting software. It has only one function, that is, slow door shooting, but it is very professional. In fact, the operation is very similar to procam, dynamic blur, optical track and low light mode. The principle is the same, except that slow shutte is more professional.

For example, in its dynamic blur, in addition to adjusting the shutter speed, you can also adjust the blur intensity and ISO. Low light mode also has noise reduction function. What is not well understood is the ray trajectory, which has a sensitivity and an ISO. My understanding is that "ISO" is to adjust the sensitivity of the whole picture, and "sensitivity" only works on the part of the light trajectory.

Procam5 or slow shutter are my favorites, one with comprehensive functions and the other with professional functions. It's just that everyone needs to pay. Procam5 should be 30 yuan, slow shutter. I think it's 18 yuan. Considering their effects and the happiness they bring us, I think the price is still worth it.
