Mick, 61, had worked for Sky for 15 years, based in Washington and then Jerusalem.
The married father of two was part of our team covering the violence in Cairo. The rest of the team are unhurt.
The Head of Sky News John Ryley described Mick as the very best of cameramen, a brilliant journalist and an inspiring mentor to many at Sky.
"Mick Deane was a really lovely, lovely guy," he said. "He was great fun to work with, he was an astonishingly good cameraman who took some brilliant pictures.
"But he also had a first class editorial brain. He had brilliant ideas.
"He was also good fun after the job was done. He was laid back, and I'm really going to miss him, like lots of people here."
Sky's Foreign Affairs Editor Tim Marshall called Mick "a friend, brave as a lion but what a heart… what a human being".
Reuters journalist and photographer Asmaa Waguih has been hospitalized in Egypt after being shot in the leg according to Twitchy and reports from Twitter.
More than 100 people have been killed in Egypt as violent protests continue. The military is currently in charge of the country, but the interim vice president resigned today.
An end to the violence doesn't seem to be anywhere close as talks between Muslim Brotherhood supports and the military repeatedly collapse. Secretary of State John Kerry made a statement condemning the violence and described it as "deplorable."
Mohamed ElBaradei, the No. 2 man in Egypt's embattled interim government, abruptly resigned Wednesday in an apparent split with the nation's leader, as fighting intensified between security forces and supporters of the Muslim Brotherhood.
In a resignation letter sent to Interim President Adly Mansour as the day's death toll from clashes throughout Egypt mounted, ElBaradei cited "decisions I do not agree with" regarding the government's crackdown on the political turmoil which began on July 3 with the ouster of former President Mohammed Morsi, Reuters reports.
"It has become difficult for me to continue bearing responsibility for decisions that I do not agree with and whose consequences I fear," ElBaradei wrote. "I cannot bear the responsibility for one drop of blood.''
"The United States strongly condemns today's violence and bloodshed across Egypt," Mr Kerry said.
"It's a serious blow to reconciliation and the Egyptian people's hopes for a transition towards democracy and inclusion."
Mr Kerry called for restraint on all sides, but said the military and the interim government it installed in July had a "unique responsibility to prevent further violence".
