Your pictures: Black and white

Each week, we publish a gallery of readers' pictures on a set theme. This week it is "black and white", and we begin with this picture by George Swann of Corfe Castle in Dorset, southern England.

Nicola Kelleher: "The light through the clock face gave the shadows in this photograph, taken in Paris, its monochrome effect."

Daniel Furon: "Black and white coffee cups and saucers of Cafe de Stijl, San Francisco, California. De Stijl was a Dutch art movement [that started in 1917] and was mainly based on clean geometric abstraction."

Eddie Dodd: "Sycamore gap in Northumberland. The sunrise was disappointing but the scenery wasn't. This was all about the texture of the rock in the foreground against the tree in the background."

Kizzie Murray: "Forgotten Britain is a personal project I've been working on for the past few months on homelessness. Walking through urban streets in Britain, such as in London, Slough and Leicester, for example, I'd walk past homeless people. After a time their faces would linger in my mind, remembering the moments where passers-by would turn the other way pretending not to see them or often cross the road."

Kevin Donegan: "I was returning home after work one day and was greeted by this glorious scene. It was so stunning that I immediately got off the bus and shot a load of images with my Canon EOS 650D (which is pretty much always with me). The scene is looking across East Float Dock in Birkenhead, towards Liverpool. The sky was rich with reds, pinks and purples, but the details came alive when I converted the image to black and white."

Andy Booth: "I spent a dinner hour snapping people walking past. This shot just seemed right."

Cristina-Ileana Ureche: "This picture of the Eiffel Tower in Paris was taken during a shower of rain on a day when the weather was changing every hour."

Gary Cox: "I wanted to capture the harsh texture of the rhino's skin and felt that this would be more obvious if the image was black and white. The resulting picture is definitely one of my favourites."

Tony Hawkins: "I shot with a 10-stop neutral density filter last summer before converting to black and white. I tried to show the rust on the pillar of the pier at Southwold [in eastern England] and I think the conversion suits the image."

Gaston Maqueda: "The great wildebeest migration arrives in the Serengeti."

Sean O Riordan: "The rays of the sun illuminated the seed heads of the dandelion plants, turning the ground into a sea of silver."

Aleksandra Walas took this picture at the Field Museum of Natural History, in the US city of Chicago.

And finally, a photograph by Michael Ayling. The next theme is gardens, and the deadline for your entries is 24 February. If you would like to enter, send your pictures to yourpics@bbc.co.uk. Further details and terms can be found by following the link below this gallery.
