With a live model and no more than 2 hours to complete the study, an artist must learn to capture likeness while presenting the subtle values between light and dark as seen with the naked eye in ‘real -time’. Whether using simple charcoal and pastel, or a full color oil palette, perfecting these skills is essential for the artist’s work to look three dimensional and ‘life- like’.
Quick study renderings are not meant to be completed works of art. But the more experienced artist will still achieve a distinguishing over all quality worth preserving.
While many artists, out of necessity, create their portraiture from photographs, the most renowned artists have learned to interpret color and temperature from live models so well that it clearly distinguishes their work from ‘photo copy’ art.
