The results show that the dynamic spatial resolution in time direction has been improved by 15-20% when the aperturestop width is properly enlarged.
分析结果证明,在适当扩大孔径光栏宽度后,在时间方向上的动态空间分辨率可提高15~20%。

Usually one can first meter using a larger aperture (so that the metered exposure time is under 30 seconds), then stop down as necessary and multiply the exposure time accordingly.
