Eastman Kodak, synonymous with "good photography" for more than 100 years, has filed for bankruptcy. Its brightest hope is sale of the patents that helped to create an art form. Remember film? In the 1980's, Eastman Kodak employed 62,000 people in Rochester New York, 130,000 worldwide. Last year there were 7000 in Rochester and 17,000 worldwide. But the loss of jobs is the only casualty of the filing for Chapter 11. Eamonn McCabe is Picture Editor for the Guardian newspaper and a photographer himself.
