AFAIK, no camera will give you TTL on B. After all, the whole concept of the B setting is to override every attempt from the camera to electronically control the shutter. It stays open as long as you say so... The trick of putting LX on Auto and manually firing the flash is an excellent

With flash you can go as slow as you like. :-) But TTL will not work unless you have the LX on Auto. The trick to include ambient light is to put the flash to manual, and leave the LX on auto. Then you decide how much flash you want, and let the LX decide how much ambient light is needed in

Hi, Jeff. Congrats on your LX. It's _the_ camera for night shots. The TTL will not work on Bulb setting. You'll need to use the LX on Auto for that. Floodlights are usually high-pressure sodium lamps. They emit a rather narrow spectrum which produce an orange/grittybrown/yellow cast. Colour

Note also that there's much difference between the old type sodium lamps and the newer high-pressure vapour ones. The older type emits light on only two distinct wavelengths, both in the orange part of the spectrum, and can for all practical purposes be considered a monochrome lightsource.

Thanks for the input on the flood lights. I had a feeling that they were not going to be any true color temp and should have said so in my original posting. I am going to shot it and see what happens once it gets a bit warmer. The orange may look good? Never know till I try. :-) Black and white

You can expect orange. If these are the common sodium vapor lamps I suspect they are, they emit a line spectra and therefore the concept of color temperature cannot be used. There may, for example, be _no_ blue at all to be had. Color temperature can only be used to describe the spectrum emitted
