Action cameras like the Xiaomi Yi/GoPro/Kodak 360 are more suited for this than people think. Their strong points is the size which makes them discrete, but also the unique fisheye perspective and field of view that makes it possible to get very close.
Because of this you can take photos without looking, you use your instinct and usually you get what you think inside the frame.
Also superb for making intentionally blurry photos in lower light, when motion can become art, with such a wide angle there is a lot of threshold, although this takes practice.
Examples taken with Xiaomi Yi/BRUNOPIX:
Kevin Carter (September 13, 1960 in Johannesburg South Africa – July 27, 1994)
Photo journalist haunted by the horror of his work….
He was a photojournalist covering conflicts like the last years of apartheid, seeing people getting executed or set at fire through the lens, something no human being can live with.
His most famous photograph was done when he took the trip to southern Sudan… while the famine suffering. He captured one of the strongest photos ever of a girl collapsed on the way to the feeding center. While a vulture landed near by, waiting for the child to die. The photograph won the heavy prestigious Pulitzer prize in 1994.
However Carter was heavily criticized for not helping the child, even though they were told not to intervene because of diseases. He later said he regretted it, and after capturing the photo he chased the vulture away, and that he cried for twenty minutes under a tree.
After the Pulitzer prize Kevin Carter was one of the most sought after photojournalists, many wanted to sign him, but Carter’s work wasn’t something you did to feel good about yourself… he was said to be a man of tumultuous emotions which brought passion to his work but also drove him to extremes of elation and depression.
“I am depressed … without phone … money for rent … money for child support … money for debts … money!!! … I am haunted by the vivid memories of killings and corpses and anger and pain … of starving or wounded children, of trigger-happy madmen, often police, of killer executioners…I have gone to join Ken if I am that lucky.”
“I’m really, really sorry, but the pain of life overrides the joy to the point that joy does not exist”.
Two months after being awarded the Pulitzer prize, Carter committed suicide by carbon monoxide poisoning, at age 33.
