By looking for unconventional viewpoints and qualities of light, great painters like Monet breathed new life into the seascape genre of painting. In choosing this unusual keyhole view, he was clearly interested in image-making not just plein air painting.
Image-making gives a work an iconic quality that remains in the imagination of the viewer for a long time.
To make a strong, interesting image it is necessary to simplify and unify the composition and avoid scenes that have been painted to death.
Image-making can involve the use of some kind of visual ambiguity. In this work the eye sees the gap in the rock as both a figure and a frame.
