A photo of a mirror in a mirror.

I will frame my question with an an assumption, as such both are obviously open for discussion and opinions...
A photo can only capture a moment. What is a photo of a mirror reflecting a mirror capturing?
I'm having trouble reconciling the way that time as a linear construct could work in such a photo.

A reflection
I'd imagine it as the pathway of a travelling photon going at the speed of light (299 792 458m/s)

I'm specifically talking about the repeating nature of a mirror in a mirror and phenomenon of the corridor effect. a constant back and forth.
What is the photo showing? The past, a moment, the future or all three....maybe at once. Why has the finite photon suddenly been able to multiply to the infinite and yet be captured in a still?

Okay, the photo was an angled reflection but you're talking about a corridor effect.
It's still the same thing just with 2 parallel mirrors bouncing light back and forth. And yeah 1 photo can capture 1 moment.

Was it a moment, or a picture of multiple moments.?

There is never, and has never been more than one moment at the same time. There is now.

Does that now, have a capacity for the infinite? Could this moment be infinite reflections?

Light redshifts over great distances so I guess not.

Try this..... Imagine two mirrors apart in distance by 600 000 000 miles facing towards each other, if an observer was to look into one mirror it's would take another 2 seconds for the image of too get back effectively giving him a vision into a past moment in a new moment(or the same one), the same is true 1 Metre apart......I know this isn't anything new. I just find it interesting that within a captured moment seemingly the past can also be present or I'm missing something.

So then the reflection can't be infinite as it would eventually dissipate.

According to modern science isn't the universe and light itself under going total and constant entropy? If the reflectuon isnt infinite could what we are seeing be a decaying moment.?

the length of the moment is your shutter speed.
you would use a longer shutter speed in low light, and probably a wider aperture - maybe 1/16th of a second or longer.
in bright light you would have a shorter shutter speed maybe 1/60th of a second.
Light can go a long way in such time periods. 186,000 miles per second...

Does the moment have to be defined by our own perceptive limitations, or can you allow a moment to consider a reality outside of what we can frame easily.

A moment is in itself an arbitrary segment of time. To be a segment of time it will be neither infinitesimal, nor is it infinite.
When you measure very small units of time, you will discover some aspects of physical reality that are only true in the context of the particular time slice in which you are measuring, while over a longer segment of time other aspects of reality prevail and some smaller grains of reality vanish.

Perhaps the truest nature of time is in the totality of a moment, the rest are merely inward reflections.

a moment has to be sized, moment in time is analogous to particle in matter. the following particles have different scale but they are all very small: molecule atom nucleus proton quark lepton etc.

"a moment has to be sized" Inherently or because we need it to be.

Just a Moment, yes it does have to be because a) we don't just wait forever, and b) there is no default size for a brief unit of time which is what a moment is - unless you have some other basic meaning for "moment".

I think I've got it with your help....The shutter speed of the camera allowed the photo to show a portion of time in which the photons had travelled back and forth multiple times, is simple am slow. What would a theoretical camera with the shortest shutter speed or "moment" capturing ability see with the same objects set up....maybe one mirror in a mirror or still the same corridor effect.... Thanks for your replies btw
