Charitable organisation Building Trust International has launched a photography competition inviting architects and designers the world over to celebrate ‘a world of opposites’. Amateur and professional photographers are invited to submit pictures that splice two images together in a split-screen effect, highlighting the similarities and differences in the world. Click here for more information.

The first prize is a Digital SLR camera - or cash equivalent if the winner already has one - and the front cover of Building Trust International’s 2013 calendar. The full calendar will be made up of 12 shortlisted entries. Anyone interested is invited to submit their image into one of the following categories: landscape; architecture; people; money; time; and work. If your image doesn’t fit into one of these, please submit it into the ‘open’ category.

Final date for registration - 1st Nov 2012
Closing date for all submissions - 1st Nov 2012
