I Love Painting on Stretched Canvas but It’s too Floppy

Image

How Can I Paint the Mona Lisa in an Hour?

Image
The painting of the Mona Lisa by Leonardo da Vinci is the most famous portrait in the world, partly due to the subtle and hard‑to‑define shadows around the face known as sfumato . Sfumato is one of the painting modes of Renaissance art and is difficult to achieve. I decided to paint the Mona Lisa and post it on YouTube as speed art. Here are the common pitfalls of painting a face with a subtle expression. Tips on Painting the Portrait of the Mona Lisa See my two YouTube clips on painting the Mona Lisa. The first glaze (above) was completed in around twenty‑five minutes. Once the first glaze was touch‑dry, I began the second glaze (below), which took a further half‑hour.

The most common problems with painting a portrait with delicate detail such as the Mona Lisa are the following: 1. Expressing shadows on th...

Image

How do I Paint Reflections in the Eyes of my Portrait?

Image
Illustrating the eyes of a portrait will make or break the oil painting; but the highlights in the eyes are equally crucial. The portraitist might take great pains to achieve great skin tones and suggestion of hair with a good likeness to the subject and then with the finishing touches applies highlights to the eyes as two white pinpricks. Whilst this might be acceptable, why leave it there when a more sensitive depiction of reflections in eyes could make a good portrait brilliant? Painting Highlights in Eyes Painting Reflections in Eyes I have written a separate article offering tips on painting eyes in portraits .
