Its next to impossible
to predict when a multicoloured sunrise will occur; most of
my images were captured down to good luck and getting up very
early (I'm not the best in the world at doing this).
I do follow some
guidelines which you may find helpful to plan, in my mind,
for these most beautiful occurances of nature.
You need to find
out the periods of civil twilight "The Twilight Zone"
which occur before sunrise and after sunset where you live.
A useful website to find this out is the U.S.
Naval Observatory. If you don't live in the USA you will
need to find out your latitude and longitude and your time
zone relative to the Greenwich (Prime) Meridian. You can find
out your position by using Multimap.
Make sure you're
in position to view the sunrise or sunset at the start of
civil twilight; this is when most of the beautiful colours
occur but before you do, check the weather forecast. If the
weather is 100% overcast or 100% clear you'll almost certainly
not see anything. You need some material in the air like dust
and clouds to bring out the colours.
Protect Your Eyes. Even light from a low sun is damaging.
