Looking south it's easy to identify things: any of the Pentlands and Cauldstaneslap. The original photograph is amazing for showing Spartleton. It's a hill I've never noticed, except the day I was on it.
On Tuesday in the Pentlands I walked three hours with 30 metre visibility, then it rolled back and I could see snow 120k away in the north. While Beinn a'Ghlo can be picked out in detail, north east of that is just a jumble. On Capelaw, I pointed my camera north and when I got home, I saw I'd taken this. Don't know what it is, though I was guessing Caenlochan.
