One of the greatest challenges for an artist in this period was to capture the effect of light on water.
Imagine trying to paint a river which is constantly moving, where the colours are ever-changing and the weather conditions varying.
It is not surprising that most of these paintings are empty of any other form of incident.
The paintings in this group highlight the differences in technique and artistic intention of artists tackling similar subject matter.
There is a definite shift from a realistic to a more subjective representation of the theme.
If we were to summarise these changes, we could say that artists moved from painting what they knew to be there, to what they could see, to what they felt.
