Slide 1
Sfumato blends tones without a hard edge
Sfumato describes softly blended transitions that avoid a hard boundary. Leonardo used this effect in modelling faces and other forms.

The term refers to a smoky appearance, but it does not mean that literal smoke is represented. It names a way that painted tones pass gradually into one another.
Slide 2
A face can emerge without a continuous outline
A painted face can emerge through changes of tone rather than a sharply drawn outline. Its edge may seem to dissolve into surrounding shade.

This makes the border depend on the relationship between neighbouring areas. The viewer reads the form through transitions, rather than following a continuous dark contour around it.
Slide 3
Softness can rest on detailed preparation
Leonardo's softly modelled surfaces did not require him to abandon preparatory design. Detailed drawing could precede the painted effect.

His surviving cartoons show sustained planning of figures and relationships. A finished appearance that feels elusive can therefore rest on deliberate and carefully organised preparation.
Slide 4
The Virgin of the Rocks connects figures with their shadowed setting
In The Virgin of the Rocks, figures occupy a shadowed rocky setting. Soft modelling helps relate their bodies to that surrounding space.

The National Gallery's painting is a second version of the composition. Comparing versions adds a question about artistic revision, beyond identifying the technique in one familiar image.
Slide 5
Naming the effect does not reveal the complete recipe
Recognising sfumato describes how transitions appear. It does not by itself tell a viewer the complete material sequence used to make them.
More to Read
Leonardo also produced softly blended modelling in drawing. The visual idea can cross media, so identifying the effect and identifying the paint materials are separate tasks.
