I wonder what background I can use. What background is better?

-Mate black background, so the lamp is floating in the dark.

-Standar white background

-A green or blue screen for then insert in a color gradient by computer, something like James pictures.

-Keep how I shoot my pics

-A scene, like a wall with objects or somehing similar.

Single color fine textured fabric works well. You can leave it as the background, dont have to chromakey it

I think I will use my existing scenes. See here

It gives an old enviroment, with the white mud wall.
