Tips on Oil Painting - Canvas Priming
When you refuse to buy any of the pre-fabricated canvases you can always buy a roll of primed or raw canvas cloth. The first step in the process towards constructing a finished canvas is the stretching of the canvas. Once the stretching is done it is time to prime the canvas cloth if you bought a roll of raw canvas.
The reason it is necessary to prime a raw canvas is that both linen and cotton cloth will eventually rot when saturated with Oil Paint. To prevent the occurrence of rotting the canvas cloth must be treated with a glue or gelatin solution to so-call "size" the canvas and then coated with an oil-based primer.
Here are the steps to be executed in the priming process:
1) After stretching the raw canvas, evenly brush the weak glue or gelatin solution onto the raw canvas using a wide nylon or bristle brush. Note, do not stretch raw canvas too tight, because the priming will shrink the canvas cloth and therefore tighten it automatically.
2) When the fabric dries, coat it with a mixture of white lead in oil and turpentine, again using a wide brush. The brilliant white surface that results makes it easier to gauge the colors you will be using while you paint.
3) Once the canvas is dry, sand it lightly.
4) Then, apply a second coat of the white lead in oil and turpentine solution, and sand the canvas again.
All these materials and the accompanying instructions can be bought in a serious art supply store or on the Internet.
Many artists also enjoy working on wood panels, which is a proving support for oil painting. The Old Masters worked on oak, poplar, and mahogany, but today "wood panel" can mean anything from a piece of poplar to plywood to Masonite. The latter is increasingly popular because it is inexpensive, durable, and can be cut into virtually any size.
Wood panels are perfect for rendering intricate, detailed subjects where the weave of the canvas might be too uneven. You can buy prepared boards or you can make your own. You must prime the panel with gesso before you begin painting. Dilute the gesso with water; apply it with a wide housepainter’s brush, let it dry, and then sand it smooth. Repeat the process two or more times. If you like a slighter rougher tooth, add less water and do not sand the board.
You can also oil paint on watercolor paper or vellum. You can size the paper with an acrylic medium first so that the oil paint does not eventually rot the paper. If you want to make your painting last longer (permanence) you need to choose heavy paper of at least 200 lbs.
This is the end of short primer on priming different grounds for the purpose of oil painting. There is much more to learn but this will give you enough information to go to a reputable art supply store and be able to converse intelligently on the subject of priming and priming methods. This will certainly start the conversation and you will learn right there about the latest techniques and inventions regarding priming and while you’re at it also about stretching canvases.

Process of Oil Painting
The process of oil painting differs from painter to painter, often but it includes certain customary steps. First, the artist prepares the surface. Although surfaces like linoleum, pressed wood, wooden panel, and cardboard have been used, the Most Popular surface and often used is canvas. While many painters have used panels for paintings (for instance Da Vince’s Mona Lisa) these can be susceptible for cracking and it is fairly small. Stretched Canvas has no such problem.
Conventional artist’s canvas is made up of linen, but anyhow less expensive cotton fabric then gained popularity. First the artist prepares a wooden frame called a “stretcher” then the canvas is pulled across the wooden framed and stapled toughly to the back edge. The next step is to apply a ground to isolate the Canvas From the acidic qualities of the paint. The canvas is normally coated with rabbit skin glue and prepared with subsequent layers of finely ground chalk.
Later the process was altered to sizing of rabbit skin glue with following layers of white priming. The artist may apply many required layers of gesso, sanding every smooth after it dries up. It is possible to tone the gesso to a particular color, but normally store-bought gesso is white. The gesso layer would tend to draw the oil painting into the porous surface, depending up on the thickness of the gesso layer.
Next the artist may sketch an outline of their subject before applying pigment to the surface. Pigment is normally mixed with oil, usually linseed oil but other oils might be used as well. The various oils dry differently, which create assorted effects. Handling and mixing the raw pigments and mediums was excessive to transportation.
The painter most often uses a brush to apply the paint. Brushes are normally prepared from different fibers to make different effects. Sizes of brushes even create different effects. “Bright” brushes are used to apply broad swaths of color. The artist may also use paint with Palette Knife that is flat, metal blade. A palette knife might be used to remove paint from the canvas when necessary. Painter may also use unusual tools, such as rags, sponges and cotton swabs. Some artists even paint with their fingers.
Most artists paint in layers, a method first introduced in the Egg tempera painting technique, and then adapted in Northern Europe for use with linseed oil paints. After this layer dries the artist would apply "glazes" to the painting, using a process of "Fat over Lean" that means more oil paint ratio than the previous layer. This method is known as "Alla Prima." When the image is finished and dried, an artist will normally seal the work with a layer of varnish usually made from Damar gum crystals dissolved in turpentine. Contemporary artists increasingly defy varnishing their work, desire that the surfaces remain varnish-free indefinitely.
Task Lighting: It refers to the higher level of light offered specially at work areas such as kitchen islands, countertops and desks. Additional light could be redirected to these areas using recessed or pendant fixtures. Fixtures with either low or line-voltage halogen offer a whiter, warmer light. 5 watt xenon or halogen lamps spaced 6 inches apart are most suitable for task lighting purposes where the fixture is within 24 inches of the work surface. The transformer is as well included in many low voltage fixtures but it is sometimes separated depending on the particular fixture and style.
Accent Lighting: Accent lighting is approximately four times the level of ambient light in any area. Same again, Halogen lighting type fixtures offer a whiter, brighter look than standard incandescent or florescent type of fixtures. The chosen fixture needs to be directional on swivel type fixture to aim the light exactly where it is required. For further museum-type effect, some fixtures could include a focusing lens for pinpoint accuracy.
Wall Washing: It is again a type of Accent Lighting, which creates an area of uniform illumination, which might desirable for a series of photos or further artwork. Wall washing typically reduces the texture of wall surface. Often the reflected light could even create ambient light in the remainder of the room that appears pleasing and restful.
Wall Grazing: It is just opposite to Wall Washing, it creates a dramatic highlight and shadow effect on surfaces such as draperies, stone or brick. Ceiling light fixtures for Wall Grazing are placed near to wall in order to highlight the three-dimensional effect.
Lighting that is perceptively measured and organized could make a real difference and will bring an improvement that lasts for years together. Many home improvements Stores also have sample displays of different lighting systems and fixtures. As today there are huge variety of appliances and electronics, lighting fixtures available, be sure you purchase from reputable company. There are numerous online retailers, which offer name brand fixtures delivered to your door at very competitive prices.
