If you're an avid Strobist, you know that the Strobist community is all about off-camera flash. In fact your submitted images can be removed from the pool if you use an on camera flash (there are exceptions to anything, of course, but as a general thumb rule this is how it goes).
The only exception allowed is "FWIW, on-camera flash is fine if it is used to trigger other off-camera flashes", I assume that this exception was set in place for those who can not afford wireless triggers or only have one slave flash with an optical sensor.
This thing is that triggering a slave with an on board flash may impact the lighting of an image. even if you set the master to its lowest output three is some light coming from that flash.
Now, it is it fill you are after, this may actually be a conscious decision, but if you want no flash at all coming from on camera, there is a simple hack to make only optical sensors magically see the master's light burst. I call it The Dark Master. buehahahahahahHAHAHAHA! Click to continue ›
