Frage von happyhour:
I use the video data set (LED ring beams) on special reflective material.
The key is now quite good, however, arises in the shade (eg, if the presenter moves his arms, and so the shadow falls on his clothes) synonymous transparency on the shadow.
Does anyone know why this is and what you can do about it?
Antwort von deti:
Typically, retroreflective material should not diffuse reflections. Could it be that the scene is illuminated in general too little - maybe more light helps so that the shadows are not as strong.

hmm .. yes that might be where I am a surface with 750W lamp and two lamps with 100w have built up.
It is synonymous so that the greater the intensity of the LED is light, the darker the person. But when I put the LED ring to minimum, then the person is very bright ..
I do not yet quite understand, synonymous

It is synonymous so that the greater the intensity of the LED is light, the darker the person. But when I put the LED ring to minimum, then the person is very bright .. This is already clear, since from the perspective of the camera is yes, then the background is lighter or darker, resulting in the adjustment of the aperture.

can be set as anything s.der camera that takes the foreground synonymous hell?

Antwort von deti:
One can use the Aperture manual but synonymous - that is on the EX3 this magical switch "Iris" directly s.Lens, must be brought into the position "manual". Then you can adjust the aperture ring of hand. This is the very thin ring, which is milled zahnradartig continuously, has no leverage off and is very close to the body of the camera.
Caution: If you make the aperture too much on, then the background will outshine the subject in the foreground.
