Learnt a new trick from Joe Buissink about using flash in TTL mode, bouncing
light off walls instead of ceilings. This way you get a directional light
from one side instead of flat light from above. Also you don't have to worry
about the power setting of the flash. I know lots of pros only use flash in
manual mode, and off camera, but Canon's 580EX II is such a powerful/smart
flash, if you don't study the TTL and make good use of it, you are wasting
it. The light bouncing off a wall is a huge light source, and the light will
wrap around to create beautiful shadows. In this photo, I face my cat to a
wall, and bounced light off that wall. Look at the catch light in her eyes.
It looks like the cat is facing a window.

Sorry but this is not new, and TTL works all the time,bounce or not. I heard
Nikon TTL even works better.

can you explain what your aperture should be, and how do you set exposure,
and how far this bouncing wall can be away?

I use Nikon, don't have Canon to compare personally, that's what I mean "
heard". But I am satisfied with Nikon TTL so far, even with 3rd party lens.
I have had SB-24 with F4 several years ago, and I always bounce the light
all over the place, not just the ceiling. That is how the flash light is
designed for, rotate the head not just up and down but left and right. When
bounce off a wall or any object, the wall distance and color are very
important. A lot people ignore the color of the wall or ceiling. I am not
trying to be a master here, but just want to point out that this is not a
new thing.

These questions are case by case, don't you think so? With modern flash
light and camera, setting aperture is no longer for how much amount of flash
light you can obtain, but how you want your ratio of flash light and
surrounding light to be as well as your desired DOF.

谢LZ分享,好片。
这种bouncelight的办法在别处也看到过,就是没自己试过。买得外闪灯快
一年了还没用过,汗一个 :(
除了墙,好像还可以是反光板,还可以先射墙,再反光板,由反光板射到被拍主体上等
等。

diffusing or bouncing 应该是最基本的闪光灯用法。NIKON内置的闪光灯可以用来做
commander,实现多灯联闪,非常实用,
