When I shot these photos, I did not have a timer cable release with me. If I were to shoot these at a small aperture, I would have to set the camera on bulb while keeping my finger on the shutter release for the entire exposure. To minimize the risk of completely ruining the photos, I've decided to vary the aperture values for the different exposures instead of varying the time and keeping a constant aperture value.
Note that it is generally not recommended that you vary the aperture values for images intended for HDR processing. If you use software like Photomatix to perform tone-mapping, for example, the varying levels of focus on the photo will create blurry results. I have had to apply a bit more USM than usual for this image. And if you view large, you can see that the grains are quite visible.
I am happy with the HDR result though--the wider aperture gave it enough exposure to show the golden reflection under the bridge, and the small aperture contribute to the oh-so-gorgeous star bursts from the lights.
