Photochromes are vibrant and nuanced prints hand-coloured from black-and-white negatives. Created using a process pioneered in the 1880s, these images offer a fascinating insight into the world when colour photography was still in its infancy. A Tour of the World in Photochromes is at the Swiss Camera Museum, Vevey, until 21 August. Here: Street food in the Strada del Porto in Naples, Italy, 1899.

We – Verena Popp-Hackner and Georg Popp - are professional landscape photographers. While we are based in Vienna/Austria, running our own (rights managed) image library and a small but fine photo-gallery. Photographing our tiny country Austria, with all it's culture and nature, canoeing it's rivers or lakes and hiking the Alps is our profession but our photographic “backyard” includes the rest of the planet as well. We use analog large format cameras almost exclusively for our landscape work, shooting on 4x5” sheet film, to provide clients with the maximum of print-sharpness and details and unsurpassed clarity and depth of focus.

Japanese artist Mami Kiyoshi has spent 15 years creating vivid portraits of people surrounded by their belongings – from wine bottles and violins to the odd stray pet. Mami Kiyoshi’s ongoing series “New Reading Portraits” is, in part, a nod to the mise-en-scène found in traditional woodcut printing. Here: Sakura and Kazuhiro, Tokyo, 2015.
