The only place that you are allowed to take photographs in Falkland Palace is in the basement which, like all basements, is ill-lit. I took this, but couldn’t get the colours right, hence the conversion to B & W. I leave it to others to see what they can do, both with colour and with noise:
I get the impression that a window to the right was letting in some daylight causing a blue tone to appear. That could probably have been isolated and neutralized when I did the processing.
