For black and white pictures, or 4 different poses, or whatever...
I just found this on the Post Office website:
"4 different poses colour or b&w photographs - £4.00" (http://www.postoffice.co.uk/portal/po/content1?catId=63400715&mediaId=19800198)
Anyone used a photo booth in a PO that *did* offer B+W/different poses?
Intrigued, I guess. Cheers!
