Basic question about the nature of light and time

Click For Summary
The discussion explores whether a high-speed camera could record the progression of light, particularly its reflection off surfaces. It questions if such recording could allow an observer to perceive light as moving slower, potentially contradicting the principle that all observers see light traveling at the same speed. However, it concludes that even with subjective time dilation, the measured speed of light remains constant. The conversation also touches on the concept of "slow light," noting that its reduced speed is due to absorption and re-emission in materials, not a fundamental change in light's velocity. Ultimately, the consensus is that light's speed is invariant regardless of the observer's processing capacity.

Imagine you have a high-speed camera with a capability to record almost near infinite frames per second. Would you be in principle able to record progression of light (I know that light itself is invisible so at least its reflected progression let's say off a room's walls after a light bulb has been lit).

If yes. I would like to know if it is possible to see its progression to be slowed down even for an observer who would have the mental capacity to process that many frames per second of information that would allow him to react to its progression? Wouldn't this violate the law that "all observers see the light moving with the same speed"?
The deeper question behind therefore is if the speed of light is also not depended on our mental capacity of how quickly we can process our input information? With speeds of regular objects this seems to be the case where with the higher frequency of input information processing the time seems to slow down and we are able to see objects moving slower or at least react on them as if they effectively were.

The shutter of the camera can't move faster than the speed of light even in principle ;).

That's OK. I don't want to see the light stop, just to see it slow down a bit on the recording.

No.

Think about it: what if not light itself does a camera record?

Silly me. I didn't realize that velocity V=(Δd)/(Δt) so even when you make time run subjectively slower a second will remain a second even when it will last subjectively longer. Therefore the measured velocity will be the same for both types of consciousness.

Btw, the slow light would't help much because as far as I know its slower group speed is caused by its absorption and consequent re-emission as this is the way light moves in those materials.
 
In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...
