Description

This is a memorial to old days, when I was using my D7000 (modified to Mono by myself) and w/o a lot things (CCD, OAG, remote control). Those days are tough, especially in the winter of Beijing, -10 degrees and hevy wind.

Went suburb of Beijing four times to finish this picture, and was glad to see IFN there.
