Illusions

"Never point your camera at the sun," they say. But rules are made to be broken.

Mid-afternoon, over the White Rock beach.

Why does the horizon sometimes curve upwards? All the explanations I can find say it's an optical illusion, but the camera sees it, and drawing a straight line, edge to edge, leaves a gap in the centre. There must be a better theory!

A Skywatch post.

  1. Nice shot, I'm sure that optics somehow plays a role but I don't worry about it.

    The distortion is in the camera lense. It's got a bit of fisheye/sperical distortion in it. Really good lenses correct for it and you can use Photoshop. http://helpx.adobe.com/photoshop/using/correcting-image-distortion-noise.html
    Great blog!

  7. Pretty shot. Like Tom said, it's in the lens. I notice it more with wide angle lenses, and not at all with standard lenses.

  8. Thanks, all!

    It's the lens? That makes sense. The camera was Laurie's little Pentax point and shoot, and it has a good zoom.
