Hong Kong at Dusk (I haven't a clue how this can happen!) Place your cursor at the top of the photo. You will notice it is 6:10 PM. Bring the mouse down slowly over the photo without pressing the button on the mouse. Do not right or left click. As you scroll down, Night time will appear, the lights will come on, and at 7:40 PM, it's dark! I think this is photo technology at its best!
