此篇博客介绍了如何使用Python 3.7.0和相关模块piexif和Pillow来批量处理子文件夹中的图片，将xxxC.jpg和xxxB.jpg的时间戳设置为xxxA.jpg后续的100到500秒，并保持相机参数一致。重点是通过set_file_time和changeDate函数实现时间调整和元数据更新。

问题描述：

某一文件夹下有N个子文件夹，子文件夹内的图片均为3张，且命名方式为xxxA.jpg，xxxB.jpg和xxxC.jpg（xxx为子文件夹名），要求将所有子文件夹内xxxC.jpg图片和xxxB.jpg图片的拍摄时间修改为xxxA.jpg拍摄时间的后续100~500s范围内，且每张图片的创建时间/修改时间均为自己修改后的拍摄时间，xxxC.jpg图片和xxxB.jpg的相机参数/手机参数与xxxA.jpg相同。

使用工具：python

版本：3.7.0

模块：piexif(1.1.3)，Pillow(7.2.0)，win32，easygui(0.98.2)
