Photographers Sjoerd Spendel & Lennart de Jong from Holland started the '365-Days' project on Tumblr. 'One photograph a day, for 365 days. The only rule: every picture must be in black & white.' Their aim was to improve their photography and capture the zeitgeist of their year. Three years on, their blog has attracted over 300,000 followers.

Three years ago the photographers Sjoerd Spendel & Lennart de Jong started the '365-Days' project on Tumblr. 'One photograph a day, for a period of 365 days. The only rule: every picture must be in black & white.' Their aim was to capture the zeitgeist of their year. Three years on, their blog has attracted over 300,000 followers. As De Jong says 'at 50,000 followers we thought this is crazy, it's a stadium full. But interest in our project just kept growing'. Now their work is available as a beautifully crafted photographic book based on their blog, in which anything from a road trip with friends, to a pint of beer, pictures of cats or the buttons on a Parka are shown. Random comments may or may not accompany the pictures and the book will also include much original photography not shown online.
