{1}水肺潜水摄影的技巧水肺(英文缩写为SCUBA)又叫自携式水下呼吸装置,人们潜入水中,必须依靠它来自由呼吸。水肺潜水摄影(简称水下摄影)指的是摄影者携带水肺潜入水下所进行的摄影活动,图1。由于潜入水中每增加10米,水中的气压就增加1个大气压,水肺具有自动调节压力的功能,使潜水者能够呼吸到与地面空气相同压力的空气。目前的水肺一般允许潜水者在不超过40米深的水下工作两个小时。
Scuba diving photography skills Scuba (abbreviated as SCUBA), also known as self-contained underwater breathing apparatus, people dive into the water, you must rely on it to breathe freely. Scuba diving photography (referred to as underwater photography) refers to the photographer carrying a scuba diving into the underwater photography activities, Figure 1. As every 10 meters dive into the water, the pressure in the water is increased by 1 atm. The scuba has the ability to automatically regulate the pressure, allowing the diver to breathe the same air as the ground air. Current scuba diving generally allows divers to work under water for no more than 40 meters for two hours.
