We're half way through the Art Advent Calendar and I thought it might be nice to share one of my favourite images of the year, a digital aerochrome of the Ponte Pedonal de Ligação Baixa de Santo António in Aveiro, which is a wonderful metal structure surrounded by trees that I knew would look spectacular as a digital aerochrome. #ArtAdventChallenge, #Infrared, #DigitalAerochrome,
