Yes, that light was previously traveling along the day it was emitted from the Sun. |
Okay, so at any point in time, the light present at the film (whose wavelength interacts with the film to determine the color of the resulting photographic image) is light which has travelled to get there.
Has that light travelled from the sun to the camera by way of the object being photographed, or did it just travel straight from the sun to the camera while bypassing the object completely (i.e. without ever travelling from the object to the camera)? |
The light from the sun is at the camera if it's daylight because the stream of photons are everywhere. It doesn't go from the object to the camera. If it's not daylight, then the light must be surrounding the object, not the camera, for a picture to be taken or for us to see the object with our eyes. |
Okay, so the light whose wavelength will create a real-time image of our ball is light which has arrived from the sun directly, without previously striking the surface of the object being photographed.
In my example then, for a real-time image of a newly-blue ball, that light at the film (which came from the Sun) must be only blue in wavelength. But why would that be the case?
If the light leaving the sun is a combination of all wavelengths, then why is this light which has just arrived at the camera only blue?
Was this light also blue in wavelength just before it arrived at the camera?
How can this light now at the camera be light of only blue wavelength when the distant object has only just now begun absorbing all non-blue light and reflecting only blue light?
Why is the light at the camera only blue when it never even came from that object?
Do you really not see how nonsensical and poorly thought out this 'model' is? (Also please note that this model is
yours and not Lessans'. He never provided any model, which is why you are having to make one up as you go along.)
