Contrast and Exposure.
In the majority of landscape images the main
contrast occurs between the sky and the
remainder. The sky effect and exposure
problem can be duplicated in any water.
This first image is an example of shadowed
foliage and a bright sky. There is about 5
stops difference between the two.
The only way to take this image is to wait
for a change of lighting.
This landscape is a little different but as
often the the sky is an essential dramatic
part of the image but also that portion
that provides a large change in EV.
This version is exposed for the sky and
the foreground and middle distance is
under exposed.
This version was exposed for the fore and
middle ground. The sky is washed out and the
image has lost all impact.
There is 4 stops difference between the two
versions.
A solution for this sort of image with a fairly
well defined horizon is to use a neutral density
graduated filter to reduce the effect of the bright
sky but still maintain the detail in the rest of
the image.

Project 15: Planning portfolio.
Autumn |
Seasonal Portfolio: The crops, trees, ground all change in this twelve months. Some dramatically
and some in subtle ways.
Winter |
In the Summer the wheat is nearly ripe for
harvesting.
The Autumn shows no sign of the previous crop.
The ground has little done to it apart from a deep scarifying and a new crop of rape seed planted.
In Winter the crop has little choice but to rest under
several inches of snow.
Summer |
Spring shows the crop growing well with some
bloom already on some of the plants near the
sheltered tree line.

Project 18: Sunrise and Sunset.
Sunrise.
The 5 shots were taken over a 24 minute period
at approximately equally spaced intervals commencing before the sun appeared to when it is
well above the horizon.
The colouring changes to to one that is strongly
influenced by reds to one where yellow dominates.
The exposure over the period varied by 4 stops.
Sunset.
Colour change approximately reverse of Sunrise.
The cloud covering the sun changed over the time
span of 34 minutes used to take these images
causing the colour change from an extremely bright
yellow to a mixture of reds/yellows after the sun
sinks bellow the horizon.
The exposure over the 34 minutes varied by 4 stops.
