有时我们拍的片子上下或左右景物光比过大,若按常规扩印反差太强,无法很好地表达照片的层次及内涵。特别是那些历尽艰辛,登上高山之巅拍到的日出或日落底片,如果在制作照片时不能很好地解决这个问题的话,的确是一大憾事。 Sometimes we shoot the film up and down or around the scene light is too large, if according to the conventional contrast too strong, can not well express the level and meaning of the photo. In particular, those sunrise or sunset films that have gone through hardships and climb to the summit of the mountains are indeed a shameful one if they can not properly solve this problem when making photos.
