Amateur photographers have been given tips on getting the perfect snap to print out at home.
John Carvill, writing for the Guardian, explained how street photography is "rife with ironies and contradictions".
He noted it often depends how the person being photographed reacts to the picture, if they notice they are being watched at all.
Mr Carvill said: "The shots wouldn't exist in any meaningful way without the people in them, yet many of these people might, if asked, opt to remain out of the frame."
He advised amateur photographers to treat their subjects with kindness and respect if they wish to get the best possible street snaps.
The Pixma MG6250 from ink supplies maker Canon could be the ideal printer for new snappers to try out their pictures at home, according to the manufacturer of the device.
It boasts features such as six individual ink cartridges and 9,600 dots per inch resolution, as well as scanning and copying functionalities.
