Solvents and Resins In Oil Painting

August 7th, 2009

Solvents are added to oil paints for temporary change, they are designed to work in a way such that they evaporate consistently and completely as the oil paint dries. (Technically, the more correct term is diluents, as not all are solvents, but it’s not the term very commonly used.) Solvents are also used to soften resins, making mediums, cleaning up, and also for cleaning brushes. It is very essential to use solvents in a well-ventilated room and you need to remember that they are flammable (catch fire easily).

Turpentine is the traditional solvent used in the oil painting. It’s actually based on tree resin and has a very fast evaporation rate, releasing harmful vapors. It could also be absorbed through healthy skin. Try using only artist quality turpentine as the industrial variety you will find in hardware stores probably contains impurities; it needs to be colorless, like water. It is also known as spirit of turpentine, oil of turpentine, genuine turpentine, English turpentine, distilled turpentine; double rectified turpentine, or even simply turps.

Mineral spirits is based on pure petroleum and has a moderate evaporation rate, releasing harmful vapors. It is not absorbed through healthy skin like turpentine. Mineral spirits is less expensive than turpentine. Mineral spirits is a stronger solvent than odorless mineral spirits, also called as white spirits.

Odorless mineral spirits is based on petroleum and has a reasonable evaporation rate. It is again not absorbed through healthy skin. It’s quite expensive than normal mineral spirits as it has had some of the harmful perfumed solvents removed. Good brands include Turpenoid, Thin-ex, and Gamsol.

Tip: Test the quality of a solvent by putting a little on a drop of paper and to let it evaporate. If it doesn’t leave any resident, stain, or smell, it needs to be good enough for oil painting.

Resins are used to increase the shine of oil paint, reduce the color, reduce drying time of a medium, and add body to drying oils. The most used one is a natural resin known as Damar that should be mixed with turpentine as it would not thoroughly dissolve when mixed with mineral spirits. Damar could also be used as a varnish.

Art Gallery Lighting Tips

July 7th, 2009

Art galleries have very unique demands when it comes to lighting them up. Unlike most rooms that require a fine balance of task, accent, and ambient lighting, art galleries mainly rely on accent lighting to accentuate the art on display. While keeping the ambient lighting simple, you need to concentrate mainly on getting the accent lighting right for the actual artwork in the room.

Ideally, you must have a picture lighting system that can be easily reconfigured to light up relocated or new art pieces displayed in the art gallery. For several decades now, monorail lighting and track lighting are being used for lighting art galleries. Check the CRI (Color Rendering Index) A lamp’s CRI is nothing but its ability to display the colors of illuminated objects and falls in the range of 1 (monochromatic light) and 100 (the sun). Fluorescent bulbs that we commonly use have a very low CRI while incandescent lamps come with a high CRI. However, incandescent lamps are not really suitable for art galleries since they do not have the exact directional characteristics required for illuminating art galleries.

Low-voltage track and cable systems are commonly used for this purpose, as they use halogen lamps that are known for their almost perfect color rendering abilities with precise beam control. Another important factor that needs to be considered is the color temperature since it decides how colors would appear to the eye under a specific lamp. It is believed that warm colors would look more vibrant under ‘warm’ light sources while cool colors would look more pleasing under ‘cool’ lamps.

Pay attention to the beam spread abilities of a lamp. The size of the lighted area is one of the major lighting problems when illuminating an art gallery. For instance, a large cone used to illuminate a small art piece may not only look odd but also distract your attention from the artwork to the illuminated wall. It may not be always possible to change fixtures but you can certainly resolve this problem by choosing a lamp of the right beam spread. Simply put, beam spread refers to the width of the cone of light a lamp produces as you move away from the light source.

Beam spreads of lamps are specified in terms of spots and floods. While the term ‘spot’ refers to a beam spread of less than 15 degrees, ‘flood’ describes a beam spread in the range of 15 to 30 degrees. You must avoid directional cans as far as possible, since such recessed fixtures may not give enough light to illuminate an especially large piece despite their ability to rotate.

Body Painting – A Look at the Top 6 Festivals in the World

May 4th, 2009

Here’s a quick look at the top 6 body painting festivals, where they happen and what you can expect to find there:

1. The World Body Painting Festival

This festival includes some of the most stunning professional body painting to be seen in the world today. A 3 day program includes dance, music and fireworks displays, as well as many competitions. Many of the body paintings here should fall under the category of ‘fine art’ with some of the dancers body paintings simply defying belief. A very large event and certainly worth traveling for.

Where: Seeboden, Austria
Duration: Three days
Events Include: World Championships in 3 categories; night contest for UV effects, Special Effects awards; classes and workshops; BodyCircus (fantasy ball); music and dance performances; an international photo contest; and a huge fireworks show.
Artistic Range: One of the very best, with stunning range of styles and surprising themes.
Family Friendliness: Not clear, but it is in Europe, so not likely to ban under 18. However this body painting festival does not advertise itself as family friendly, as some others do.

2. The Canadian Body Painting Festival

This is another body painting festival that showcases simply stunning artists and finished work. The quality of the art here is similar to that seen at the World Body Painting Festival. The Festival is themed from year to year, with the recent theme being “It’s A Jungle Out There.” Also includes the Canadian Body Painting Championships.

Where: Nanaimo, British Columbia
Duration: Two days
Events Include: Competitions in overall body painting, brush and sponge, and airbrush; includes the Canadian body painting Championships
Artistic Range: Most stunning, and one of the best overall. Very life-like and fantastic double-take images.
Family Friendliness: Not stated – would be worth making a call first.

3. The International Body Painting Festival

This festival takes place in Mainz, a city with over two thousand years of history. It is located on the river Rhine, has strong Celtic roots and may have been founded by the Romans as early as 13 BC. One can imagine that body painting has a long history here, if you remember the Celtic tradition of painting their bodies before going into battle. Once again, the artistic ability and range is stunning at this International festival.

Where: Mainz, Germany
Duration: Weekend festival
Events Include: Competitions include special effects and face painting
Artistic Range: Very stunning; high artistic skill.
Family Friendliness: Not known but again, it’s in Europe. I would call ahead.

4. Welsh International Body Painting Festival
This festival is a bit younger and less established than the top 3, although it has some impressive artwork considering that they are just getting started. Also the atmosphere is more ‘fun’ orinted, less ‘high art’ and family participation is strongly encouraged. A good festival to consider if you want to make it a family outing and see some amazing work in the process.
Where: Wales (of course)
Duration: Two days
Events Include: Hands on demonstrations; horror specialists and flower specialists
Artistic Range: High, and impressive for a smaller sized event; not as subtle or creative as some of the others
Family Friendliness: Very good; in fact they encourage families and camping, with an ‘all ages’ atmosphere and events designed for younger participants

5. The UK Body Painting Festival

This festival showcases some of the least impressive – although most amusing – body painting, although it should be said that it is not presented as a stuffy ‘high art’ affair, but more a circus or county fair type outing for the entire family. Fun, relaxed and un-selfconscious atmosphere allows for some of the more surprising and purely ‘fun’ body art to be seen. If you’re not a supermodel and would like to get your body painted without worrying about snide comments, this might be a good option for you.

Where: Ashford, UK
Duration: Two days
Events Include: Family-oriented face painting, body painting competitions for professional and amateur categories, craft fair, children’s activities, workshops, and a ‘bouncy castle.’
Artistic Range: Fair; more of a family outing with a lots to do than a showcase of spectacular art.
Family Friendliness: Very high; advertised as family event. Lowest cost of all the body painting festivals – comparable to a movie ticket.

6. The US Bodypainting Festival (or New Mexico Body Painting Festival/US Bodypainting Competition)

There is definitely some impressive body painting to be seen at this festival, and a lot of creative innovation with hair and unusual designs that you won’t see anywhere else. One example that springs to mind is a model dressed in racecar theme with red, white and blue hair sprayed out behind her as though flying in the wind. Also, if you’re in the US this festival obviously doesn’t require a plane ticket. However this is not a family outing, as it explicitly bans anyone under 18.

Where: Alberquerque, New Mexico
Duration: Three days
Events Include: Demonstrations, workshops, competitions in body painting
Artistic Range: Good to poor – there is a mix of very impressive artistic works and things better left unpainted here; although it’s all ‘interesting.’
Family Friendliness: Not at all. We are in the US remember; no one under 18 allowed.
