Close Examination of Sir Archibald Alison

I shot this bust of Sir Archibald Alison at the Scottish Portrait Gallery today and decided to do two things:
1. Process the image slightly to liven it up, and 
2. Do a little research into Sir Archibald
Briefly Sir Archibald Alison (1792 – 1867) was a Scottish advocate and historian.
But like many of his time, it appears that this gent had connections to the slave trade.
I found research carried out by University College London under their Legacies of British Slave-ownership project discloses that Sir Archibald Alison benefited from the compensation paid out following the abolition of slavery in 1833. 
According to records, he benefited from a payment of £4,081,18s,10d to be precise. That's approximately £346,000 in 2015 values - payment  made by the UK Government as recorded by the Slave Compensation Commission and records held at the National Archives in London.
