Wireless Flash

Tested wireless flash this evening, there was a poser duck at the university lake area stayed still as my model.
So you can see the effect of different position of the flash and how it brings impact to a portrait photography.

This was shot with the flash mounted on the camera, so it's a direct flash like what everyone does with a point and shoot camera.


This was shot with the wireless flash placed on the left side of the duck.


This was shot with the wireless flash placed on the right side of the duck.


This is the last one, was shot with the wireless flash from top, notice the shadow direction?

So which one you prefer?
