把灯左转60度,打到墙上反射,还能有TTL吗?还是必须心算了?
如果从背后反射,光强又不一样了,TTL能处理这些复杂情况吗? | t*****c 发帖数: 118 | 2 In this case, TTL won't give you the right exposure sometimes, especially
the reflecting surface is over or under-reflective.
In theory, you could do calculation, but do you really want to measure
bouncing distances while keeping your subject in focus?
I'd take a couple of shots, look at histogram, and dial in manual
compensation on the flash. That's it. | r***6 发帖数: 401 | 3 In my experience with Nikon system (d90 plus sb600) the exposure is mostly
right. I routinely bounce flash to the upper left so it gives the subject
somewhat more 3d feel. In typical indoor home situation most time it is
adequate.
That said, canon flash system (t3i and 430exii) gives less consistent result

One crucial point you need to pay attention to is use CTO (orange) gel to
match the color of indoor lighting. Otherwise the color can be really weird.
Sometimes I like use orange gel for the subject with background of natural
light. This can give nice effect where the subject is warm with cool
backlight of blue hue. This really can enhance the skin tone with a nice
contrast.
In large indoor situation bouncing lght won't work well because the
reflecting wall or ceiling are too far away.

我从没有用过Gel改变颜色,我发现把白平衡改到日光就可以了,闪光和室内环境光
可以很好地混在一起。如果不想闪光的效果太明显,可以用自动白平衡,把闪光补偿
减一挡。
result
weird.
natural
