and  Support. The picture shows a flourescent lamp with segmental reflectors. The background is necessarily black, otherwise the lamp would be too bright. Roger McLassus 11:18, 3 February 2006 (UTC)[reply]
How can you tell the colour of my lamp? -:) Seriously - the colour is intended, because the luminosity of the lamp is reduced to enhance its visibility. This reduction means a decrease in ratiation temperature and therefore a redshift according to the laws of physics. Apart from this, the topic of my picture is not the flourescent lamp but the segmental reflection with leads to the (at least for me) attractive effect of repetition.

Ehrmmm... "redshift" is something else (check the wikilink). And it's only incandescent lamps that get really reddish when dimmed. This is fluorescent, right? I bet the color is more due to the color temperature setting on your camera. --Janke | Talk 08:56, 11 February 2006 (UTC)[reply]
Your reply made it clear to me that I misformulated what I wanted to say. I didn't manipulate the lamp itself, only its apparent luminosity by selecting a very short exposure time. By the way: I didn't mean the redshift of the Wikipedia-article (I am a physicist myself and quite familiar with this concept). The word "redshift" has more meanings, some of which you find listed under red shift, but the use of one or the other spelling is rather arbitrary. Roger McLassus 15:34, 14 February 2006 (UTC)[reply]
