Varnishing An Oil Painting

Varnish is more than simply a layer to protect your oil painting from ultraviolet light, pollution in the atmosphere and abrasion. It will also bring out the brilliance in colors, making them sparkle. Varnish is made from Damar resin dissolved in a mixture of turpentine and other organic solvents. Keep in mind that oil paint dries from the outside in; when it dries, it forms a surface skin first. During the drying process small pores form in this surface skin. The surface of the paint may feel dry, but under the skin, the paint is still wet, no matter how thin the coating is. It takes at least 6 months drying time for the dried oil paint film to become dry enough that it won't be re-dissolved by mild solvents such as turpentine. When a varnish is applied to a reproduction art oil-on-canvas painting before the 6 month drying time, the varnish fills the pores of the oil paint film, The solvent content of the varnish can easily re-dissolve the incompletely dried oil paint at the bottom of the canvas and cause all kinds of problems - such as wrinkling of the oil paint film, cracking, and yellowing of the color.

• Clean the painting so it's free from dust and dirt. Lay the oil painting flat, then dampen the surface a bit of cotton wool with clean water.

• Dry the oil painting with another bit of cotton wool. With your fingers, gently remove any cotton fibers that have been caught in the oil paint.

 

• Leave your painting to dry for several hours.

• Choose from high gloss, satin or matte finishes. Varnishes may be brushed or sprayed on. Use a flat bristle brush to apply the varnish. If you don't want your oil-on-canvas painting to be too shiny, use a matt varnish rather than a gloss one.

• With the painting flat, work from the top to the bottom, applying the varnish in parallel strokes from one edge of the oil painting to the other. Always work in the same direction. Try to have the same amount of varnish on the brush for each stroke so you put equal amounts of varnish on all parts of the oil painting. Always varnish the whole of the oil-on-canvas painting in one go.

• When the first coat of varnish is dry, apply a second coat at right angles to the first. This will give you a good, even finish.

• Leave the painting flat for at least 10 minutes after you've finished varnishing to stop the varnish running down the oil painting. Then prop it up against a wall to dry, face inwards.

• To test whether the varnish is dry or not, touch the edge of the oil painting to see if it's still tacky. It should dry within a day or two, depending on the weather.

Satisfaction Guaranteed: Purchasing a Video Camera

Finding the right video camera requires a few simple steps. Start by researching the various products available in the marketplace.

If you're unfamiliar with video cameras, doing your homework now can better ensure you'll be satisfied with your final purchase. Many consumers are use to particular brand names, and the quality and features associated with each. If this is your first video camera, you may want to take the plunge and purchase a truly top-of-the-line model, or just get your big toe wet with a less expensive unit. The challenge is in selling yourself that the extra cost, whatever it may be, will be able to generate the results you need to make it all worthwhile.

This research process can be used when making any type of photo purchase. First set the price range. How much are you willing to spend? Determine if you're looking for an amateur or a professional grade camera. Even if you're an amateur, sometimes the pro shops can offer some surprisingly accessible products. Regardless, it's helpful to go to a major photo and video supplier's Web site to check out what's available.

There's one more step to be taken. Locate other folks who had already made purchases and shared their thoughts. User expectation is a big factor in a consumer's experience. For instance, one person may make a negative comment about a feature. However, that feature is irrelevant to your need for that product. Read the good comments and the bad. Then shift through the details for what really matters to you.

Before, after or as you read consumer reviews, make a list of all the realistic scenarios as to how you plan to use the video camera. Will you use it in low light conditions? Do you care about audio? Does it need to be compact and portable? Will you need to carry it a distance? Will you be able to react to impromptu situations? Does it have a million accessories and how much do they cost? How long does the battery last? Is it complicated to download the contents? How much data can be held on the storage device? Will you need a tripod

 
The next thing, to ask yourself is "What are you willing to sacrifice to get the majority of what you want in the price range you desire?" There is no single perfect camera (in an affordable price range of most consumers). Remember that old expression, "you can't be all things to all people." It's called an average camera.

There's a professional photographer who wanted to move into video. His choice for this first-time buy was a JVC video camera. It's a lower end price range professional video camera ($2,000-ish). JVC has a reputation for making some great DVD/CD and stereo equipment leading one to believe that all their products should offer similar performance. The runner up was a highly rated, semi-amateur/professional Sony camera in a mid-range price ($1,200-$1,300). Then there was the highly-rated Panasonic for $900. It was reported that the results for this camera in low light conditions were poor and grainy. All things considered it was still a good camera. Like all video cameras, the built-in audio is considered sub-par. If you plan to digitally add sound that should not be an issue.

So ultimately what was the professional photographer's choice? The photographer opted for the Sony.

Buying cheaper is not always the best option. Being happy with the equipment and using it rather than having it sit in the box makes all the difference.
