Ok, this is something I have not seen before. With the big war on who has the bigger better accessorizeable speedlite diffuser there has been a ruling paradigm – bounce your flash to get softer results.
If you are a Strobist fan, you are going to love this. Presslite
just came up are about to release a new concept for flash modifications – Vertex.
They do not try to diffuse the flash, nor bounce it from the ceiling. Instead they try to break the flash power into two halves. This is done using two mirrors, each to control half of the flash output.
Now think of the options – you can bounce half of the flash from the ceiling or from the wall while you direct the other half to your subject. You can control the spread of light. And you can direct your flash anywhere you want to. Nice.
I guess that one question that has to be asked is how sturdy is the Vertex. By aiming it towards a press audience I would think that it needs to be strong to take the abuse pros give their speedlites.
Check out the 3D demo – it is hypnotizing.
