I don't think this looks like streaks of sunlight at all. Sun does not just stop and start. It is gradual and fades away kinda like a rainbow. It is also very very hazy. These lines in the picture are sharp like a sword.
This looks like hair to me, but it's so very white. It almost looks like the picture had something wiped across it, yet it couldn't have because I can see the woods in the scene through the streaks and also because nothing else is smudged. Even the streaks are not smudged, they are very clear. Odd picture...DeniseNH
