Vantage Point

The challenge for today is altitude. When I checked the definition it seems there are different ones depending on which category you are referring to, e.g. aviation, geometry, geographical survey, and sports all have a somewhat different definition. I'd like to add a photography category. I would define altitude as a vantage point. From which height can you get the best shot?! I've tried various heights - from planes, mountains, towers and hills. Our altitude (geography version) is approximately 670 meters above sea level, not high enough to affect baking or cause altitude illness. For this photo I was on a small bluff , at a vantage point overlooking some of our downtown buildings. (With a little help from filters in photoshop, I created this more artistic effect.)
