Oil painting is a traditional art form known for its rich colors, depth, and versatility. Because oil paints dry slowly, they allow artists to blend colors smoothly and make corrections over several days. This guide provides a series of tutorials and essential tips to help you start your journey into oil painting with confidence.
Understanding Oil Painting Supplies
Before you begin your first tutorial, you must gather the necessary materials. Unlike acrylics or watercolors, oil painting requires specific tools to manage the paint’s consistency and drying time.
Essential Paint Colors
You do not need a large set of colors to start. A basic palette of “primaries” allows you to mix almost any color you need. Look for student-grade or artist-grade tubes in the following colors: Titanium White, Cadmium Yellow, Ultramarine Blue, Alizarin Crimson, and Burnt Umber.
Brushes and Palettes
Oil painting brushes are typically made of stiff hog hair or synthetic fibers designed to handle heavy paint. You should have at least one large flat brush for backgrounds, a medium round brush for shapes, and a small detail brush. For a palette, a simple glass sheet or a disposable paper palette works well.
Solvents and Mediums
Oil paint cannot be thinned with water. You will need Odorless Mineral Spirits (OMS) to clean your brushes and thin the paint for initial layers. You may also want Linseed Oil, which is used as a medium to make the paint more fluid and glossy.
Setting Up a Safe Workspace
Oil painting involves chemicals that require proper handling. Always work in a well-ventilated room to ensure that fumes from solvents do not accumulate. If you are working in a small space, keep a window open or use a fan to circulate air.
Protect your flooring and furniture with drop cloths or newspapers. Because oil paint can take days or weeks to dry, ensure you have a dedicated area where your canvas can sit undisturbed. Keep your cleaning rags in a metal container with a lid, as oil-soaked rags can be a fire hazard if left in a heap.
The Golden Rules of Oil Painting
To prevent your painting from cracking as it dries, you must follow two fundamental rules. These rules are the foundation of all successful oil painting tutorials.
- Fat Over Lean: Always apply “fat” paint (paint with more oil) over “lean” paint (paint thinned with solvent). This ensures that the top layers dry slower than the bottom layers, preventing cracks.
- Thick Over Thin: Start your painting with thin, diluted washes of color. Save your thick, heavy applications of paint for the final stages of the work.
Tutorial: Basic Painting Techniques
Mastering a few simple techniques will help you achieve professional-looking results. Practice these methods on a scrap piece of canvas before starting a full project.
Underpainting
An underpainting is a thin layer of paint applied to the canvas to map out the composition. Usually done in a neutral tone like Burnt Umber, it helps you establish the light and dark areas of your subject without the distraction of full color.
Wet-on-Wet (Alla Prima)
This technique involves applying wet paint directly onto wet paint. It is ideal for blending colors smoothly on the canvas. Because the paint remains wet for a long time, you can move it around and mix it directly where you are working.
Glazing
Glazing is the process of applying a thin, transparent layer of paint over a layer that is already dry. This creates a luminous effect that adds depth and richness to the color. It is a common technique used for skin tones and atmospheric landscapes.
Step-by-Step Tutorial: Your First Still Life
A still life, such as a single piece of fruit, is the best subject for a beginner. It allows you to focus on light, shadow, and form without the complexity of a landscape or portrait.
Step 1: Toning the Canvas
Cover your white canvas with a very thin wash of neutral color using a large brush and solvent. This removes the “fear of the white page” and provides a middle tone to work against. Wipe away any excess liquid with a paper towel.
Step 2: Sketching the Subject
Using a small brush and thinned paint, lightly sketch the outline of your subject. Focus on the basic geometric shapes. If you make a mistake, you can easily wipe it away with a cloth dipped in solvent.
Step 3: Blocking in Values
Identify the darkest areas of your subject and fill them in with a dark color. Then, find the mid-tones. Do not worry about details or perfect colors yet; focus on making the object look three-dimensional through light and shadow.
Step 4: Adding Color and Details
Once your values are established, begin applying thicker paint in the actual colors of the object. Use your medium brush to blend the edges where shadows meet the light. Add the brightest highlights last using a small amount of Titanium White.
Cleaning and Maintaining Your Tools
Proper maintenance will ensure your brushes last for years. Never let oil paint dry on your brushes, as it will ruin the bristles. Follow these steps for effective cleaning:
- Wipe off as much excess paint as possible using a rag or paper towel.
- Swish the brush in a jar of Odorless Mineral Spirits to remove the remaining pigment.
- Wash the brush with warm water and a mild soap or specialized brush cleaner.
- Reshape the bristles with your fingers and let the brush dry flat.
Store your paints in a cool, dry place. Ensure the caps are screwed on tightly to prevent the oil from leaking or the paint from hardening inside the tube.
Conclusion
Oil painting is a rewarding hobby that offers endless opportunities for creativity and skill development. By starting with the right supplies and following the core rules of “fat over lean,” you can create vibrant works of art that last for generations. Remember that patience is key, as the slow drying time is one of the medium’s greatest advantages.
