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.

The incredible photographs show the three alligators crowding around the man’s head as they look directly at the camera and one even appears to sit on his lap whilst another reptile places a claw on his arm as it swims towards the surface. Photographs taken from above the surface show animal handler, Chris Gillette (29) from Fort Lauderdale, Florida, USA holding an alligator out of the water. The images of Chris were taken by Michael Dornellas at the Everglades Outpost Wildlife Rescue, Florida USA. Here: Mich­ael Dornellas brings the beast up close and personal to the camera.
