Any "best of" list must surely be subjective. This one is no different. Choosing the best photographs of the year is an enormously difficult task, with many terrific photographs slipping through the cracks. But with major news events as a guide, and with single images I fell in love with throughout the year forcing their way into the edit, I look at my favorite pictures from the first four months of the year. Two main stories dominated headlines in the first part of the year: the Japan earthquake and tsunami, and the rising of the Arab Spring. The protests in the Middle East would spread to Greece, Spain, and eventually inspire the Occupy movement in Western nations. Other stories included a historic wave of tornados in the U.S., a Royal wedding in London, and the creation of the world's newest nation in South Sudan. Images from the rest of the year will follow in posts later this week. -- Lane Turner ( 36 photos total
