Funny question, I know, but as I am very preoccupied with the capture of Light, I wonder if it comes in beams/rays or in bunches?
Reason for my question is, that on my own pics it seems to come as beams/rays, but I see some other pics here, where it more seems to diffuse as bunches.
Is that because of HDR or .... ?

Lars :-)

Depends on the drugs you are doing on any given day...

Oh, yeah, and a few atmospheric conditions and something called occlusion...

Light comes like particles or as a wave and has both properties. It is called wave?particle duality and is a basic concept in quantum mechanics.

Pretty cool you see it in photographs ;) Like Clyde said, it must depend on the type of drugs one is doing...

You rock Paul...

Interesting read...

Oh it can also come in plugin form with can give you bunches, rays or anything else you want. ;-)

Lars, if you want to understand it deep, you should study physics. It's really cool playing with light. But it's more cool to play with tachyons.

Words cannot describe just how much I disagree. ;)

As for your question Lars my advice would be:
Build a wall with two windows that face into the sunrise/sunset. Stand at a 90° angle and maybe your question as to whether the light in those images is real or not. Or just wikipedia it.

I believe that Einstein was awarded the Nobel prize because he proved the dual nature of light.

For the most part the wave/particle duality has little to do with photography. There are a few quantization effects at the extreme limits of detector technology, and wave diffraction can be a limiting factor on sharpness at small f-stops. Bright light behind a sharp edge can produce some visible diffraction effects too, but that's about it. Large luminous elements such as beams and rays are just patterns of light and shadow being dispersed in some medium such as mist.
