Exercise_Standing back (this is .doc file has full details on this exercise)
For this exercise I have used my lens Canon EF 24-105 mm f/4 L IS USM. I haven’t faced any practical difficulties apart from the fact that I wanted to be as unnoticed as possible. One might say that the glass was on obstacle but I tend to love both glass and frames. I don’t mind the reflections but this is a matter of taste.
