I did try that but in the original image at full resolution it's pretty much the same but thanks buddy, was a challenge but they have accepted it and are more than happy with the end result. Thankfully because I accidentally deleted the .psd
I checked the blue channel and got quite a bit of info from that and ended up making my own/adding someone else's. Not ideal but got in pretty much spot on from what I could see. I always find that using the blue channel on damaged photos can reveal lots of info that would otherwise be lost or not visible.
