Most journalists today are a far cry from the mythologized war correspondent coping with internalized images of violence, suffering and despair through stiff drinks and bawdy jokes. Like every human being, newswomen and men suffer emotional consequences from their work.
When specific photographs become symbolic of a particular event, triggering the public's memory (and related feelings and emotions) about that period in time, we can refer to them as enduring historical icons.
Remember: Everyone in your newsroom may be affected differently. Some may be affected immediately while others will take days, weeks, months or even years to see the effect. The journalists who either claim or seem to be the most unfazed by the event may, in fact, be affected the most. Others may have developed mechanisms to help them deal with tragedy, and they may have minimal effects.
