~ Today was the final examination and last class of the Autumn, 2012 Peking University class…after a class portrait taken by MU Tong, using a tripod, I walked into Zhongguancun in the freezing sub-zero afternoon air, with last night's snowfall reflecting the sunlight…from Ms. CHU Pei I purchased a SanDisk 32 GB CF Card for use in the 1D Mark IV camera, an NB-10L extra battery for the PowerShot SX40 HS camera, and a Canon Timer Remote Controller, TC-80N3…the timer remote controller may be very useful for taking starlight photos in Africa…it will also facilitate very long exposure night landscape shots
