And while there are those tanning bed users who understand the beds, there are those who still think that they are cheating the dangers of the sun by choosing a tanning bed instead.

In truth, the harmful effects of tanning beds are just the same as the sun. Consequently, like the sun, tanning beds should be approached cautiously. First and foremost, fair-skinned people should avoid tanning beds -- and the sun -- at all costs. Even if you have darker skin, exposure should be limited. If you find that you just can't stay away, keep exposure time to a minimum and try to visit only periodically. Intense and prolonged exposure -- while increasing dangers -- also has the unsightly ability to make users look a little "too tan."

But more importantly, the harmful effects of tanning beds include the burning and aging of skin; prolonged exposure can even result in skin cancer. Tanning beds give off UV rays that are just as dangerous as the sun. If you find it necessary to visit a tanning bed then offer your skin just a little bit of covering with protective lotions designed for your skin type. Always be sure to protect your eyes, as well, with special glasses. Most include eye protection with your visit.

Tanning is a risk that each one of us must decide upon for ourselves. If you must tan, do it responsibly to minimize the harmful effects of tanning beds on your skin.

And a lens or two to go with it? That's great. Now all you have to do is learn how to use it. I'm assuming here you bought an SLR camera because you want to do a little bit more than take at family events and holidays. So for those new to photography as anything more than that, this article aims to give you a little background on the basics of exposure to help you on your way.



There are two elements to creating a "correct exposure". These are , and shutter speed, which we will look at first. When you press the trigger button on your camera to take a picture, it opens a set of sliders, like opening a window. How long it stays open, depends on how you set the shutter speed. can range from extremely fast (ie 1/8000 of a second), to very slow (30 seconds), or even infinity if your camera has a bulb setting. These are extreme shutter speeds and not often used, except by people who shoot fast moving subjects, or in very low light. For most of us, we tend to stick to somewhere in the middle. As a general rule, the faster the shutter speed, the sharper your photo will be. For most people, anything at 1/60 of a second or above is acceptable when hand holding a camera. Lower if you have a particularly steady hand. If you need to use slower shutter speeds, you will need to use a tripod or rest your camera on a steady surface. These slow speeds can be particularly useful for creating blurred effects. For example the flowing water in a waterfall.

Aperture

Ever wondered how photographers get their subjects to really stand out by blurring the background? The secret (which really is no secret) is adjusting the aperture. The aperture changes the in your photo. Depth of field is how much of the image is in focus. For example, if you have a depth of field of 4 meters, anything within that distance of the subject you are focusing on will also be in focus. There is as much variety with this control as there is with shutter speed. You can choose to set a narrow aperture (long depth of field) when you want the whole shot in focus, for instance a great, sweeping landscape, or a wider aperture for portraits.

Ok, so you've got your shutter speed sorted from your aperture. Now we just have to put them together. Any SLR camera will have an inbuilt light meter. This little gadget measures the amount of light you will need to create a correct exposure. It is usually in the form of a little bar with a too high (+) and a too low (=96) sign at each end. It is simply a matter of balancing one against the other so that the meter is centered. Once you've done that you can press the button! That's all there is to it.

ISO

Another choice that will effect your exposure is the ISO you use. With film cameras, this means the speed of film that you use. If you use a 100 speed film, your ISO is 100. Digital cameras also have an adjustable ISO speed. It's just in the form of turning a dial instead of loading a different film. A general rule is to use the lowest ISO you can get away with. Higher ISO films or digital settings can result in noisy (grainy) pictures. They do, however, allow you more freedom in your exposures in that you can shoot with less available light. Experiment with your particular camera, see what you can get away with. Remember that the quality required will be different for everyone. If you only want to make small prints to put in an album, or just store the photos digitally on your computer, then you will not need the same quality as if you want to make large prints to hang on your wall.

So there is some food for thought for those starting out in photography and looking to do more than just point and shoot. Now it's time to go out there and shoot. Experiment with different settings. Try new things. The technical side of photography you can read about anywhere. The creative side, well, that's up to you.

The two are related because much of what can be done to protect the health of one can also be done for the other. In fact, hair and skin care are inseparable when it comes to maintaining health and an overall pleasant appearance. But such maintenance relies upon a few general tips that must be followed consistently as part of a hair and .

First and foremost, as part of an effective hair and skin care regime, proper cleansing is paramount to success. For hair that means a mild shampoo that works within the confines of your particular hair type; for skin it means a gentle cleanser and toner that is made for your skin type. In either case, over washing can yield unpleasant results; both hair and skin will become dry and lifeless in the face of excessive washing.

Equally important in effective hair and skin care is . Your skin should be treated to a daily dose of - and even more often for dryer skin. Again, the type of moisturizer you use depends on your particular type of skin -- whether it's oily, dry, combination, or acne prone there is a moisturizer for you. Hydration for hair means a proper conditioner designed for your type of hair and meant for frequent use. For particularly dry hair, you may want to treat yourself to a deep conditioning treatment once or twice a week.

Hair and skin care also means protecting yourself from damaging elements such as the sun. Long-term exposure to the sun can result in early aging of skin and hair. Hair becomes brittle and dry; skin becomes weathered and damaged. Such exposure can even result in . Limit your exposure to the sun as part of your hair and skin care; wear at all times -- even in the winter. And for those who are particularly fair skinned, wear a hat as much as possible during the summer months -- limiting your hair and scalp's exposure to damaging rays.

Take the time to care for yourself. Proper hair and skin care requires a commitment to a consistent regime that will strengthen you hair and skin and deliver you to a higher level of good health and radiant appearance.

This site discusses what asbestos is, asbestosis and other diseases caused by asbestos, pleural thickening, mesothelioma, lung Cancer, prevention, asbestos in buildings, and compensation. This form of cancer is peculiar because the only known cause is from asbestos exposure.

National Cancer Institute, found that people who live closer to ultramafic rock deposits, which typically contain asbestos, have higher risks than those farther away. That was before studies linked with cancer and lung disease. The delay between exposure to asbestos and the development of cancer is generally 20 or more years.

The type of cancers includes mesothelioma, asbestos lung cancer, and asbestosis. The known afflictions associated with asbestos exposure are asbestosis, lung cancer, mesothelioma and pleural plaques. Significant long term exposure to asbestos increases the risk of lung cancer, mesothelioma and non-malignant lung and pleural disorders.

Smoking also greatly aggravates the likelihood of lung cancer in workers exposed to asbestos (although smoking does not appear to increase the risk of mesothelioma). The asbestos fibers can and other lung disease that may not appear until many years after exposure. But exposure to asbestos causes cancer and other diseases.

British were among the first who were observed to have lung cancer related to asbestos. Because of the recent renovation boom, home renovators are the new suffers of asbestos cancer, or mesothelioma. Scientists have developed a blood test that can predict years in advance whether someone will succumb to asbestos cancer.

Sunlight harms your skin, most particularly the upper layer of skin known as the epidermis. The ultraviolet light of the sun damages fibers in the skin referred to as elastin. Dermatologists have a special term, photoaging, for the premature aging caused by exposure to the sun's rays and this condition occurs over a period of many years. Fair skin tends to show signs of photoaging more profoundly than dark skin because of the level of pigmentation in the skin.

Signs of damage due to exposure to sunlight include wrinkles, roughness, leathery texture, age spots, blotchy pigmentation and a reduction of flexibility. Skin that has been hurt by the sun may also be more prone to bruising. A major cause of is the damage done by exposure to the sun. Exposure to the sun can also include tanning since you are still putting your skin into with simulated sun rays.

There are several ways to minimize the damage done to your skin from exposure to the sun. For effective treatment, avoiding the sun between the hours of ten in the morning and three in the afternoon, when the sun is strongest, is helpful.. Use a sunscreen or moisturizer with an SPF number of 15 or higher to block harmful rays. The higher the SPF number, the more protection the sunscreen offers your skin. Wear protective clothing, such as hats, sunglasses and light, long-sleeved shirts to shield the skin from sunlight. Also, keep away from the use of or .

The negative effects of sun exposure have been well documented, as have the . But for tanning bed enthusiasts, the associated with tanning are difficult to ignore. To weigh your risks when it comes to tanning, it's important to first understand some tanning bed facts.

One of the most important tanning bed facts to understand is that tanning beds do not eradicate the dangers of ultraviolet rays. Most of us know that the sun emits ultraviolet rays =96 rays =96 that have been associated with everything from early aging to significant skin damage such as skin cancer. But what you must also understand is that tanning beds also emit these ultraviolet rays. While exposure to the more dangerous UVB rays are minimized in tanning beds, these UV rays still exist. Additionally, tanning beds actually increase exposure to =96 longer that reach our deeper layers of skin =96 to speed the tanning process. For skin that has a tendency to burn this can mean a speedier burning, rather than tanning, process.

Another one of the tanning bed facts to understand is that visiting a tanning salon does not mean you should leave your protective lotion behind. Rather, you should be just as vigilant in selecting protective lotion at the tanning salon as you would on the beach. One of the tanning bed facts that most people don't realize is that there are lotions designed for specific skin types that are meant to provide protection in tanning beds. Any reputable tanning salon will offer a full product line of protective lotion; ask an employee for help finding one that works with your skin type.

The most important of tanning bed facts is that a tanning bed does not change your skin. If you burn at the pool then you will burn in a tanning salon. If you have fair skin that tends to burn, you're better off avoiding tanning beds altogether. But if you must tan, do so responsibly and with knowledge behind you.

Natural sunlight produces ultraviolet light -- made up of UVA rays and . UVA -- the longer wavelengths of sunlight -- causes the skin to tan. Experts agree that excessive and long term exposure to UVA rays can -- and other sun-related skin damage. UVB rays -- the more dangerous of the two -- consist of shorter wavelengths that burn the top layer of the skin.

Tanning beds expose users to nearly 40% less of UVB rays than the natural sun, minimizing some of the danger. But the health risks of tanning beds still exist, as the skin is still exposed to both UVB and UVA rays.

Extremely fair-skinned people -- those who burn easily in the sun -- should avoid tanning altogether. The health risks of tanning beds for fairer skin is multiplied than for those with a little bit darker skin. However, skin of all colors should be vigilant when examining the health risks of tanning beds. And, if you do decide to use a tanning bed, then be sure to give your skin some protection with lotion made for your particular skin type. Also be sure to cover your eyes at all times during tanning; eye protection is normally offered through the tanning salon.

Using shallow depth of field for stock photos enables you to isolate the subject very easily. Having an isolated subject is very important. People that are advertisers don't want to buy stock photos that are cluttered and filled with detailed backgrounds.

Setting a shallow depth of field will make the stock photo much more profitable in certain situations. If you're taking an expansive , shallow depth of field probably wouldn't be your best option.

for which shallow depth of field work good for include a few categories. The possibilities, however, are endless. Shallow depth of field could be greatly used when taking pictures of a product. Isolating the product will bring more impact on the object. It could be used when taking photographs of people. It could even be used when photographing small objects of interest.

A shallow depth of field makes the object of interest more interesting. Having a simple background brings more impact to the subject of interest. Do not, however, think that the background is only a useless part of your photograph.

When setting the background up, even though it's out of focus, be sure that it adds something to the subject. If your subject is a duck then having an out of focus lake is a much better option than a white blank background.

In case you don't know, shallow depth of field is created by using a very large aperture .Using a large aperture lets a larger amount of light in. Having more light in makes the light that is let in lees detailed and thus creates a blur on certain parts of the photograph. such as F/5.6 or F/2.8 work great for shallow depth of field photographs.

With stock photos if you took a photograph of an object it can be greatly enhanced if you turn it into a shallow depth of field photograph. For example, let's say you took a picture of a salt shaker and the background was a kitchen fully in focus. You could open the photo up in an editing program and blur the background slightly or extremely. This will make more impact on the salt shaker.

An interesting way to use shallow depth of field in stock photography is when you take extreme telephoto lenses. I'm sure you have seen the pictures of very small objects and only a piece of the object is in focus. Everything else, the front and back, are out of focus. This shallow depth is achieved by using a very small field of vision. It is very interesting to play with the different effects of shallow depth of field. But always be sure that the subject of interest is as clear and focused as possible. Stock photography does not allow room for photos with out of focus subjects. http://www.photoprofitz.com Al Sanchez has a great program that teaches how to sell pictures online ]]> Is Your Employer Giving You Asbestos Cancer? http://www.artwoo.com/article/is-your-employer-giving-you-asbestos-cancer http://www.artwoo.com/article/is-your-employer-giving-you-asbestos-cancer#comments Sat, 12 Aug 2006 02:27:07 +0000 asbestos fibersasbestos diseasesasbestos related diseasesasbestos exposurelife threatening illnessunfortunatelylung cancer http://www.artwoo.com/article/is-your-employer-giving-you-asbestos-cancer asbestos fibers brought into the home on the shoes, clothing, skin, and hair of workers.

How High is the Risk for Cancer?

Not all workers exposed to asbestos will develop diseases related to their exposure. The risk of developing asbestos-related diseases varies with the type of industry in which the exposure occurred and with the extent of the exposure. Asbestos that is bonded into finished products such as walls and tiles poses no risk to health as long as it is not damaged or disturbed in such a way as to release fibers into the air. When asbestos fibers are set free and inhaled, however, exposed individuals are at risk of developing an asbestos-related disease.

How does smoking affect risk?

Many studies have shown that the combination of smoking and is particularly hazardous. Smokers who are also exposed to asbestos have a greatly increased risk of . However, smoking combined with asbestos exposure does not appear to increase the risk of mesothelioma.

are said to follow the trail of exposure. That means that wherever people have received asbestos exposure, regardless of their trade, age, sex or race, they are at risk of cancer and other diseases.

, the effects of asbestos on the human body were known to be deadly for years by the companies who employed the 'greatest generation' and made hundreds of millions, if not billions, of dollars off of their backs. But instead of taking simple steps to alleviate the problem and save the lives of thousands of their workers, they choose to do nothing and continue to make a "healthy" profit with a "deadly" product.

A life-threatening illness is terribly emotional. It has a broad impact and affects many people - family, friends and co-workers.

Many employers even went so far as to hide the truth from their workers and their families. And because the normal latency period for Mesothelioma is 20 to 30 years, many got away with this for years.

For years photography textbooks and magazines have been promoting the idea that a wide-angle lens provides more depth of field compared to a telephoto one. However, if you type 'depth of field' on Google, you will soon come across a lot of articles arguing this assumption.

Recent tests taken by experts, including several , have proven that, technically speaking, a wide-angle length does not provide more depth of field. These tests are quite easy and you can conduct them yourself to verify the conclusions. But how does this impact your work as a photographer? All these tests assume that you keep the picture size constant. They go like this: take a photo of some subject using a telephoto and then zoom out and use the . You can also use interchangeable telephoto and . Then take the photo made with the short focus lens and enlarge a selected portion of it until is the same size as the same portion in the other photo. You will see that there is no significant difference between them. This proves that wide angle lenses don't actually provide more depth of field.

Now, let's see why you actually zoom out. Say you are in front of an amazingly , such as a beautifully colored with sunrise light. You zoom in and take the picture with a telephoto setting. Then you zoom out and take the photo using the wide angle setting. You expect to get more depth of field with the last photo and that's what it looks like. You would never think that if you enlarge a portion of it this of field will disappear. When you use a wide angle setting, you zoom out because you want to capture more things in your picture. You are aware that the objects will look smaller and it doesn't bother you. In the same way, when you zoom in you want to focus on a certain aspect of the photo even though you know you will loose depth of field. Zooming in and out and using different focal length setting makes you perceive that the depth of field also varies. Photos taken with the wide angle appear to include more depth of field compared to those taken with the telephoto. This may not be true technically. But what is in fact a photograph? What appears to the viewer. If you don't place technical correctness above everything else, you should stick to what you've known and has proven right for years. As long as you like what you get, why drop it? Your photos will prove if you are on the right path or not.Mr. D. is a writer about photo resizer software applications at Reshade.

This dive article will provide some facts about enriched air, advantages and disadvantages of diving with enriched air, and equipment used for enriched air diving.

Air is a mixture of primarily two gases, approximately 21% oxygen and 79% . Nitrogen is the culprit in causing , more commonly know as the "bends". This fact will be important as we discuss enriched air advantages. Enriched air is the result of adding oxygen to air, raising the level of oxygen in the mixture to between 22% and 99%. However, for recreational purposes enriched air blends range from 22% to 40% oxygen. Nitrox is often referred to as "enriched air"; however there is a difference between the two. Nitrox refers to any nitrogen-oxygen mixture, while enriched air is air that has some oxygen added. Therefore by definition enriched air can only contain greater than 21% oxygen. The two most common blends are 32% oxygen (EANx32) and 36% (EANx36). The abbreviation EAN stands for Enriched .

The primary advantage of enriched air is to extend the no stop limits beyond the normal no stop limits associated with air. Since enriched air has a lower level of nitrogen than air, you absorb less nitrogen while your body is able to metabolize the extra oxygen, assuming you are diving within recreational enriched air limits. This results in longer no decompression limits while diving on enriched air. The primary disadvantage of diving with enriched air is potential exposure to . Oxygen can be toxic based on depth and duration under water, and by increasing the level of oxygen in the gas you breathe, you are constrained by your depth and duration. This is why you must calculate both your no decompression limit due to nitrogen, and your limit called partial pressure. For most non- under 100 feet, you will be limited by the amount of gas as opposed to either the no decompression limit or the partial pressure limits. Enriched air is particularly effective in enhancing the frequency and duration of repetitive dives, since nitrogen buildup is lessened.

Enriched air diving within the recreational limit of under 40% oxygen requires some special equipment, but for the most part you can use the equipment you purchased for diving air. The only new piece of equipment that you will definitely need is a tank. One reason for this is the special markings that must go on an enriched air tank; the other is that the tank must be cleaned and lubricated for oxygen exposure to facilitate partial pressure blending which involves adding pure oxygen to air. A common scuba community guideline is that regulators, BCDs, SPGs and alternate air sources may be used with enriched air blends up to 40% oxygen without modification. However, you should verify that the manufacturer of each piece of equipment has certified that equipment for use with enriched air. For gas mixes with more then 40% oxygen, special equipment is required. As with any scuba equipment, regular servicing is highly recommended, including O-rings and other critical components. During your enriched air training, you will learn how to properly fill and verify the blend of gas in your tank. The verification step is extremely important and must be done by you the diver; you shouldn't rely on anyone else to verify your gas blend.

Remember, you should never dive with enriched air unless you have been certified by a reputable certification organization. While the benefits of diving enriched air are significant, so are the risks. Rick Abbott is an avid diver, part time author, and consultant in the IT field.
