Glad you like the pic - Queen's Park is a great place.
I hope this won't disappoint too much but the pic was taken with the Hipstamatic app on an iPhone. I'm afraid there was no other software involved nor secrets to share. More info here: http://hipstamaticapp.com/. I just had a quick look for filters or packages that might do a similar thing and there are a few things going on, like this: http://www.dslreports.com/forum/r24315589-Hipstamatic-Effect-Photoshop-Plugin
I absolutely love your photo of Queen's Park simply because I'm from Glasgow and most of my childhood summers were spent in that park. I was just wondering what software you used to edit your photo the way you did because I've been looking for software that does that and I can't find it anywhere.
