Mono
A monochromatic image only shows variations of a single colour: not only black and white. Mono images can convey a much better understanding of the object - colour is not there to distract, and shapes, contrasts and patterns speak out more clearly.
Scary bush
In the Dales
Northumbrian field in winter
Not in South Africa
Leaves
On the lookout
The Long March
Down the escalator
A bowl of cones
Basel bikes
