I have walked down this path several times before, to the area where I have taken all the shots of boxes. But today the path was a bit unusual.Or at least, after I placed the candles there it was.
What little light there is in the picture comes form two sources: the candles themselves, and from the flashligth I was using to illuminate the path and trees.
Pictures like this are always a bit hard, as the illumination is very much a hit-or-miss thing: you have to take a wild guess at how long you should illuminate the path, and see what the result is. For shots like this you need a digital camera, or you would get ruined by your film-and-processing costs before you get it right. Done well, though, the effects can be great.
