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.

Some people use paper as their canvas for creating works of art, Patrik Bundeli, on the other hand, uses Ping-Pong balls. His steady hand turns simple white balls into elaborate cartoonish faces. Some of his works feature black and white gothic visages, while others have adorable little snouts. The latter ones would make a wonderful addition to any working place, putting smiles on everyone’s faces. (Photo by Patrik Bundeli)

Thomas Barbèy grew up in Geneva, Switzerland, across the street from the “Caran D'ache” factory, the largest manufacturer of art supplies. He started drawing seriously at the age of 13, using black “encre de Chine” and gouaches for color. His influences were Philippe Druillet, Roger Dean and H.R. Giger. After living in Geneva for 17 years and designing posters for musical bands, he decided to move to Italy, where he lived in Milan for 15 years making a living as a successful recording artist, lyricist and fashion photographer.

Nelson Hernandez flashes the victory sign as he shows off one of the voodoo dolls that he is selling at El Viejo Lazaro Botanica to try and help the Miami Heat fans root their team on against the Dallas Mavericks in the NBA finals on June 9, 2011 in Miami, Florida. The dolls made from cotton come in white or black and they are all the same size. The user of the doll must have the name of the player attached to the doll, which is filled with cotton, herbs, sticks and a special powder. (Photo by Joe Raedle/Getty Images)
