Get closeups of the rusted ends and do it by"zooming" in. Get an overall shot, then walk closer, then closer, then the closeup ends of the wires. All of these are for perspective and make the rusty wire part of the scene not just a wire you took a photo of.I agree with everything you said, no problems at all with any of these things that would happen.
Talked to “freaking neighbors” adjuster and neighbor told him his fences aren’t great but they’re not that bad. Adjuster asked if I could get pics of neighbors fence. I walked less than 100 yards and found at least 4 places where wires were pushed almost to the ground by tree limbs, another place where wires were off the T post and separated wide apart and one place whEre multiple wires are broke and have been so long they’re rusted.
Those pictures will be your best evidence of the condition of the fence and the time it took to get rusted.
Better yet, try to get pictures of the cattle breaking in or out of the fence.
