enLIGHTen: IES International Year of Light Photo Contest 2015
In celebration of 2015 as the International Year of Light as proclaimed by UNESCO, the Emerging Professionals of IES (Illuminating Engineering Society) are giving you a reason to share your love for lighting for the next 6 months. Every month we will announce a “Theme of the Month” to which you will post “lighting” photos related to the chosen theme. You can post as many photos as you wish and at the end of each month, for bragging rights only, we will announce our favourite photo of the month. In August, a group of industry professional judges will select the top 3 entrants based on their photo originality, uniqueness, relevance to the theme of the month, activity and interaction with the public.
