网上看到这句，using the SU-4 slave mode on the SB-800 with the SB400 will
work great and is a good idea
这时候2个灯都是TTL模式吗？sb400在机身上了就没有commander了，sb800用什么触发
？红外？还是sb400的灯？

With an inexpensive ($50, incl shpng) set of eBay radio triggers you can
fire both the SB-600 and the SB-400 when they are off the camera. ISHOOT PT-

这个是怎么实现的？SB-400没有manual设置按钮哦，另外sb600会是TTL模式吗？
谢谢
