Aspiring underwater photographers are often frustrated at their initial results Cheap Panthers Jersey , which are generally in a word - terrible. All those shots of beautiful corals, fish and other reef critters you wanted to share with friends turned out blue, dull and boring.

So what's the deal? You got a spiffy new waterproof camera that takes great photos on land but when using the same camera underwater the results aren't even close. The reason is the water which being considerably denser than air Jordan Scarlett Blue Jersey , sucks up light, color, and contrast.

The first thing you noticed was all the underwater shots looked blue. That's because blue is one of the last colors to be absorbed by the water whereas the reds and yellows disappear really fast Christian Miller Blue Jersey , like in a few feet. To get color back you need to add light back by using a flash or strobe.

The next problem to overcome is that light won't travel very far through water and if you're more than a few feet from the subject, the light from that flash just won't reach. What you need to concentrate on is getting to within 2 or 3 feet of what you're shooting.

You also want to get down low and try to aim upwards a bit to improve contrast. Just like you would if photographing a friend on land, aim for the eyes to get focused.

Getting close to the subject will keep you from trying to shoot through too much water which acts like a filter and tends to make your pictures lack sharpness and contrast as things sort of blur together.

While a flash is required for getting the color back it can also cause its own problems like something known as backscatter. That's those opaque circles that may be ruining your pictures. They happen when the flash reflects off the minute particles suspended in the water directly back into the camera lens Will Grier Blue Jersey , usually from using the internal flash.

You can sometimes get away with an internal flash when shooting super macro because even a flash set next to the lens will be at enough of an angle so as not to reflect directly back, but otherwise you'll need an external flash you can mount off to one side. When setting up the strobe, be sure to disable the internal flash or just tape over it.

Also take the time to become a proficient diver Greg Little Blue Jersey , and get especially good at maintaining neutral buoyancy. You don't want to be trying to master a new waterproof camera without having mastered diving first. Having lousy buoyancy skills not only makes you a detriment to the reef, but could also get you into a dangerous DCS situation.

So the quick hits to getting better pictures underwater are getting close, getting low Brian Burns Blue Jersey , aiming up, and using an external strobe. Plus remember to avoid letting your head get so into the camera that you forget where you are. Xylitol is a sugar alcohol that can be used as a sugar substitute. The compound can be used in candies, chewing gum and toothpaste so as to minimize the occurrence of dental caries in school going children. The prevalence of dental caries is evidence that some sugars that the public is consuming remain high thus leading to the erosion of teeth. The proposal below aims to test the effectiveness of Xylitol as an alternative to sugar and its effectiveness in preventing dental decay. The study will focus on school-going children who are expected to be the participants of the study. The study aims to shed light on the use of controlled portions of Xylitol for the prevention of dental caries.
INTRODUCTION
The rise of dental caries among children has heightened interest in finding alternative ways of managing and preventing the condition. The use of fluoride toothpaste has been thought to be effective Curtis Samuel Blue Jersey , but the rising statistics of dental carries presents a different picture. The American Academy of Pediatric Dentistry has suggested the use of Xylitol as an alternative way of preventing dental caries in children. Xylitol is a naturally occurring alcohol that can be added to chewing gums or oral care products to prevent tooth decays. Xylitol is approved by the Food and Drug Administration as a natural sweetener. It has been considered as an alternative to artificial sugars that is a lead cause of dental decay and cavities.
Medical and dental professionals have considered the benefits of replacing artificial sugar with nonsugar sweeteners such as Xylitol. Xylitol reduces the levels of Mutans Streptococci (MS) in plaque and saliva by disrupting their energy production processes, resulting in unsuccessful energy cycle and cell death. Xylitol minimizes the adhesion of microorganism to the teeth surface. Xylitol also increases the production and flow of saliva thus its use in chewing gums. Manufacturers of chewing gums have introduced Xylitol as a substitute to sucrose. Other than reducing the amount of calorie consumption, chewing gums with Xylitol enhances dental care as Xylitol does not break down. The failure to metabolize means that Xylitol cannot form acids that cause dental decay. The US Preventive services task force acknowledges that dental caries is a common and chronic disease that affects school-age children.
