sometimes it is that simple

but sometimes its like you alluded to earlier in the post ...
unless your subject is in much different lighting (like deep shadow or something)
the light is only exactly the same in a wide open area and at noontime when the sun is dirctly overhead
if the light is from anywhere else ( the east/southeast/south/southwest/west ) it will not be the same
( like lighitng a cube or a face or 2 sides of s north/south axis street )
there will always be some aspects of the subject that will have shadow and the lighting will be a stop off
( or more or less ) ...
in street work this is compounded by canyoning of buildings, streets that have light wells or
bright light on some places and shadow on others ..
from my own haphazard experience using sunny 11 and photographing in mixed ( sun/shadow ) light,
there is usually a stop or 2 ( or more )
difference between the sunny side and hte shadow side of the street, and streets with no sun just flat even
l iight it is usually sunny 5.6 1/2 ...
jusxusfanatic, no matter if you use a meter or you wing it with sunny 16 you
will figure out your own way to meter a scene through your own experience.
what i tend to do is if i have use a meter i will meter/ ( or evaluate with sunny 11 ) the brightest part
and remember it, and then the shadowy part with details and remember it so
i have one side and the other of the equation and take it from there .....
good luck !
