This is what I was looking for. I find when I do night shots, even on a tripod, I get those nasty light flares. I am sure it is all knowledge based, but regardless of the SS I use, they seem to exist. Maybe aperture is the key.I wanted to pull in more light to expose in the shadows - I used HDR at +1 for several of the shots to maximize that effect with fairly large apertures which helped control the highlights (the first hotel shot, for example).
Thanks,
Rich
