The Kiss Cam

Kingdom FM have a Kiss Cam on the go at the Kingsgate. Have a look here too. http://www.kingdomfm.co.uk/gallery/the-kingdom-fm-kiss-cam-at-the-kingsgate-shopping-centre-621963/ 
It is a grey day in the grey auld toun. More colour and interest in the shopping centre. 
Following on from my last incognito blip from the pub, the smart phone camera is great for these short of shots. How easy would it be to get a shot like this with a camera looking through the viewfinder. The smart phone seems to be quite invisible.
