Extracts:
"In addition to the full-scale oil sketches, Constable completed numerous
observational studies of landscapes and clouds, determined to become
more scientific in his recording of atmospheric conditions."
and
"To the sky studies he added notes, often on the back of the sketches, of the prevailing weather conditions, direction of light .... he is known to have been influenced by the pioneering work of the
meteorologist Luke Howard on the classification of clouds"
Constables are readily available online.
However, I have become intrigued recently by image generating software Night Cafe and created some "Constables". Night Cafe is excellent when it comes to balance and composition, but frequently gets human figures out of scale. Moreover, I often find the raw output is very dark. So a quick tweak with the likes of Photoshop is often needed. Anyway, two "pseudo-Constables".
