Hi
@Jrk102688
Just wanted to be clear that what forum members share here are likely not to stand up to the legal criteria of necessary forensics so should be considered opinion back with some data for your consideration. A real forensic expert would be needed for arguments to legally hold water.
What would always be critical is the original unadulterated image or images (if a video or time series of stills) in the format that they were taken in the same resolution without any adjustments or cropping. Then know that exact original (or set of originals) more competent opinions with reasons could be provided.
Then, one could compare those originals to any adjusted images and answer questions. Note that the problem with making many adjustments is that one can turn the dial until they see what they want to see. It would be even worse if selected adjustments were made on only part of the image.
Just because one image looks better than another e.g. lower noise better tone does not mean that is the original. Poor looking images may be the original and the better looking one may be adjusted one. That is what photo restoration is all about. Better does not mean accurate to the original reality either.
When there are a series of images in a time lapse or a video there are often more information in several frames that there is in a single frame. Shadows can play a big role in determining what one is looking at and one frame may not show it will while another frame might reveal it perfectly.
So I don't know if either of the images you provided are the exact originals or not.
The very dark image in your last post is not worth anything. The vast majority of pixels are pure black with no tonal information so you can tell nothing form that image.
The heavily noise image may or may not be the origianal. It certainly is marked as if it came from a time lapse from a bank yet not clear why it would be so noisy and grainy
The larger image with less noise if the original makes it hard to explain where all the noise cam in the middle image.
So more accurate information from about the exact original or series of originals would be needed for me to make further comments. Guessing which is which would not be helpful for you or anyone.
Just my opinion
