Image
This painting featured for appraisal is a sun drenched rusty pickup truck in North Carolina, completed via oil on canvas with coarse bristle brushes. Oil Painting of Rusty Pickup in North Carolina This landscape painting , completed by an artist who wishes to remain anonymous, is only her fifth attempt at oil painting. She has found inspiration from a subject matter that personally fascinates me: how things crumble and rust through time. The artist has shown evidence of an eye for finding inspiration from the most unlikely places. Degradation of objects, such as this old truck in ruin provides endless textures, contours and hues to explore. Finding Inspiration from Rusty Objects The medium used is oil on canvas, and what appears to be of a limited palette comprising mostly yellows, blues, greens with varying amounts of white.

I Have no Interesting Objects for a Still Life Painting

Image
The artist struck by an itch to produce still life art may loot the cupboards for something interesting to paint and pass up apparently mundane objects, such as bottles, fruit or toys, for something more exotic.

What are the ideal objects to include in a still life painting?   Why Ordinary Objects Make Powerful Still Life Subjects Selecting interesting subject matter for a painting may prove a challenge if the artist is unsure of what to include. Making assumptions and generalisations about objects can often result in a still life that fails to live up to expectations. The following ideas need challenging when selecting still life objects.

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 painting 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 sha...

Some art restorers may not decide to treat it, for it is the normal process of ageing and adds charm to the appearance of the artwork. Solving the Craquelure Problem in an Old Painting This old oil landscape painting shows cracks in the paint layer called craquelure.

Tips on Painting Brown Hair for Portraits: Brunette and Russet Colors

Image
The artist assigned to paint a portrait of someone with brown hair may reach for any brown pigment in the hope that it will do, resulting in hair that looks flat, dull and wool‑like rather than fine strands. How can the artist paint brown hair realistically? How to Paint Brown Hair on Portrait The artist may reflect upon what went wrong when painting hair. Any of the following practices could be at fault: Assuming any tube labelled “brown” will represent all shades from brunette to auburn.

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

Image
Illustrating the eyes in a portrait painting 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?
