Las Meninas, Velázquez
The silhouettes of the figures that make up this painting, from Velázquez to José Nieto (the character framed in backlight at the threshold of the background door), are not isolated, forming a single large silhouette.
There is only one other isolated focal area: the mirror in the background, slightly illuminated by the light entering through the last window open on the right, where the image of the kings is reproduced. In this sense, this painting is similar to Jan van Eyck's "The Arnolfini Portrait" (Figure 11), where both the couple and the painter himself are reflected in the background mirror. In the latter painting, the "almost parabolic" distribution of the couple framing the mirror is more evident.
