Frage von he.becker:
Hello,
came across by chance on this forum. Where I was particularly the case with the Bluebox intersiert.
Now, are probably a couple of stupid questions, but still try it once.
If I have understood correctly,) is stretched behind the photographed object to a slide (like cat's eye at the bike, which throws the light back in the same direction as it strikes the film.
The real object is normally illuminated with white light.
On the camera lens is then attached to a ring light, for example, blue light on the object and the background beams.
Since the film back in the same direction so radiant, so ends the reflected blue light more directly into the lens (actually referred to the LED emits the light, right?)
Among the commercially available ring lights but it is nevertheless true that they do not radiate directly to the outside, but actually in the center of the lens (eg for lighting in macro shots or microscope).
Would it then just work with one Ringlich synonymous?, Or have the LEDs radiate outward, or at least parallel to the lens?
And how to do it with the cut of the background, one can then easily removed from the whole picture, the BLUE?, That they would then remove all but synonymous blue components of my object, and I understand this wrong?
And not caused by the blue lighting, which illuminates the object so synonymous my blue a blue stitch in my Object?
Am grateful for all the advice and tips.
MFG

Could it be that you are here, front projection and Chromakey (Blue Box) mess up? When you described method of the object would indeed be synonymous blue.
The front projection (with the described "cat's eye membrane) is a very old film technique, in which one with film projector and camera work (with both) look over a semi-transparent mirror in the same direction. Very complicated and very cumbersome.
If you want to make a Blue Box Effect (Chroma), requires only a tired blue background, there is this special substances in blue and green, and accordingly synonymous suitable wall colors. The replacement of the blue / green surface with a different picture will happen by software.
In a simple form of time (as is) to try the effect easily and quickly implemented. If there is to look really good, but it requires some knowhow and a camera with good color differentiation (necessarily 3-chip).

Nene, because nothing he has mixed up.
There are newer products, the blue box much easier to make portable and easy to save time while obviousness.
This is a set of special film for the background and an LED ring light that comes s.The Optics. Through this combination, we must illuminate the background no longer and has no more problems.
