I'll be in Lisbon from June 13 to 20.
I am interested in learning about optimal vantage points from which to take photos, particularly (but not exclusively) at night. I am thinking of the kinds of vantage points that a tourist might not easily discover just by walking around the main tourist spots or following a guidebook. For example, I've seen some great shots of the Vasco do Gama bridge at dusk and sunrise, but I'm not sure precisely where I would go to get the best shot.
On a related note, I would be eager to hear any advice regarding photography tours -- particularly night tours.
Thanks in advance!
