| for x ten times: Blue Box illumination
Question of Crown:
Januar 2006
Moin!
Yes, I know on this subject, there are so few threads, but I can never draw a concrete conclusion. So I would like to take pictures on a blue box 2,75 m x 4,50 m linen. Camcorder: Panasonic NV GS 250, software: Vegas 5;
My problem: How to illuminate??
I am looking for a cheap but still effective solution. As with fluorescent lights or construction lights are out? If we were to get a satisfactory result?
Needs to be blasted from where? (From both sides, front, top and between the screen and actor?)
Please only seriously meant, and concrete answers!
Thank you very much,
Crown

The illumination of the Blue Box should be as evenly as possible, the softer the better.
It works synonymous with construction lights, strung s.besten they (with some space so that the glass does not burst) with a thin glass fiber mat, as they exist eg for car repairs. This makes it extremely hard and soft reflectors of light evenly.
Illuminate at least two sides of any case, just so that the lighting is evenly distributed on the surface.
Fluorescent lights, because if they are strong enough, are naturally better for two reasons:
1. Their light is already very soft
2. The light color of the fluorescent tubes in contrast to the Kunstlichtbaustrahlern contains very little amount of red, representing a chroma-keying almost always meets.
Bluebox foreground object and should be illuminated in any event, synonymous separated.
The Blue Box should be about the same audio control how the foreground object, which will then be punched.
The white balance must be made in any case to the foreground object.

As you can see my Fragepsot (könnte. ..) I used the search function already. I write it nicth bequemlichkeit found out.
Thank you, but s.der illumination by ring light, I'm not interested.
So if I understand correctly, then your fluorescent tubes are already quite well for this project. Would it theoretically with 4 pieces: (?)
Links
-Right
-Front (the actor)
-Top (of the top with dazzle drawn to the screen)
It is synonymous to me clear that I try it in the end in itself deatil be, but yes Maybe someone has already designed with the method of fluorescent experimenting ....
