[技术互助] 拍了两次篮球比赛了，感觉还是不满意，求大师指点下

拓展的篮球比赛，室内进行的，灯光条件还可以，让我去拍，我也算是刚入行没多久的新手，设备是佳能的RP+24-104STM的套头。

思路是开M档，ISO和曝光自动，对焦点固定在中上方，光圈4-6左右，拍的照片基本上10张里面有2-3张对焦不准，表现为被对焦的那个人比较糊，是什么情况啊，拍了两场比赛了都是这样，挺郁闷的，还被人说拍的照片太暗了。

随机挑了8张图 [img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-j18pK2rT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-law2ZcT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-5dyaZcT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-efnaZbT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-kqnlK2hT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-1ar4ZcT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-62o8ZbT3cSsg-iy.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202010/20/-570ynQ5-e2jvZbT3cSsg-iy.jpg.medium.jpg[/img]
