HDTR image of Vancouver skyline, rendered from 60 frames taken over a 4 1/2 hour period (18.00 - 22.30).
This is the first example of this method using my dSLR. Other renders used webcam images. For a successful execution, a dSLR is necessary. I was previously counting on web cam images from www.katkam.ca, largely because the idea of setting up for a 12 hour period numbed my mind. The web cam images were fairly high resolution, but white balance and exposure were automatic, and this resulted in varying color casts (not so bad) and widely varying exposure (bad).
The relative success of the shot above is due largely to controlled exposure. For the first 2/3 of images, exposure was automatic as light levels varied from 13.5 EV (6pm) down to 7.5 at 9pm. After that, exposure was compensated from -1/2EV to -2EV to avoid filling out too many shadows as light levels dropped quickly from 7.5EV at 9pm down to 1.0EV at 9:45pm. Before the city lights turned on, images were shot at f/8, stopped down to f/16 after the lights turned on to render lights with slight star bursts (this is an effect of small apertures). All images were shot RAW.
For processing, white balance was manually set on the white dome of BC Place, a large white domed structure (see image note). Using this target, color temperature varied from 4900K at 6.30pm to 10000K at 9.30pm. As light levels rapidly fell, temperature dropped from 10000K at 9.30pm to 2900 at 10pm, when the primary illumination was the sum of city lights. The purpose of targeting a color balance source is to avoid sudden color casts in the input images, thus avoiding sudden changes in color in the direction of time flow in the final image.
