Filters are essential if you want to take well exposed
photos in extremes of light and shade.
The link in the Title Bar is useful on what to choose.
Also, carrying an umbrella is very important in
many hot countries.
Photos taken at sunset in Australia were very
pleasant and with subtle tonal range,
thanks to my trusty umbrella,
bought in Singapore as a protection
from the tropical sun.
People made some interesting comments when
they saw it, at first, but gradually realised
that it was one of the most practical accessories
a photographer could have.
