A great, unusual light shaper

This screen is definitely something special. Impressed the enormous size, and it is not too difficult to handle. One should have a screen Eiger, the one mounted so that there is a tendency to flash it and not the screen. Thus one can direct the light exactly in the center of the screen. Or you can use the same one behind the other two screen Eiger.

The best way to meter the light with clip-on and thus very good aim at the center of the screen. Studio flashes are unwieldy for my opinion too big and too. Possibly it would with a separate stand. The Aufsteckblitz turn requires a push-diffuser, so that the light is distributed evenly. Of course you can also without a diffuser, and maybe even experiment with a comb, but then one uses only the inner part of the screen.

It is often said that the form is not parabolic. I think the contrary, that this is really only be assessed with some mathematical knowledge. At first glance can not tell you that. Perhaps this screen has only the initial part of a parabola as shape? Similar to satellite dishes?

The effect of the screen is in my opinion actually parabolic. The incoming diffuse light is directed and it is illuminated an astonishingly small space with it. This surface is at 2 meters distance not greater than the illuminated portion of the screen. With greater distances I have to experiment.

In any case, you get to the screen up new possibilities for illumination, and you can make fantastic pictures with only a single compact flash.
