Shiela you are right - halogen lamps are incandescant. So that would be the correct setting.Their proper name is quartz-halogen lamps they are actually burning a small piece of quartz in halogen gas. They burn hotter than ordinary lightbulbs (tungsten burning) so actually give of a slightly whiter light. If you were not happy with the colours on an image you could alter this in PSP later using the Automatic Colour Balance and move the slider to alter the temps of the colours in you image. Richard.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
