here’s one for you csi folk.
So how would you take photo evidence that cannot be challenged?

And how would you challenge photo evidence?

Witnesses - or some very high end setup that has 3rd party verification at every stage.

If you are good enough you can beat forensic software that looks for alterations, etc. (such software has a high level of ability to tell you an image has been altered but a low level of ability to tell you it definitely hasn't - specificity vs sensitivity and all that) or any firmware level metadata, etc.

Meta data can that be altered after the photos has been taken, Ie can you change the date?
I know you can change the time stamp on a phone by changing the date and time but that only works at the time the photo was taken

So it seems you can’t know the exact time and date on all videos and pics.

All pictures and videos I have taken on my phone and camera have the date it was taken.
I was given a video which was taken on phone and put on computer, the date and time on the pc was the date that it was put on pc it shows as “edited on” got me wondering how this works for evidence

You use software that verifies the image at the moment of capture, and can tell if it's been altered due to the coding that is generated from this original process.

That's what we do at work, and it's been good enough for worldwide forensic organisations and courts for decades

what software is this?
