How to choose a good digital camera?

Electronic gadgets are totally in, and having a digital camera has become a necessity for every family. Some settle for camera phones, but these have poor resolution, lower color quality and cell phones have limited memory capacities. Digital cameras have varying features and prices. Depending on your needs, choose the right digital camera by checking out these tips:

There is no "best" brand. Liz says that there is no one brand that she can recommend over another. Choosing your camera is really a matter of personal preference, and each brand has their advantages and drawbacks. Her only advice is to stick with a major brand like Pentax, Nikon, Kodak, Canon or Olympus. Photographs taken by any of these cameras will be high quality and suitable for selling your finished beadwork online.

Decide what you want your camera to do. Before you go shopping, decide what you want your camera to do. Do you want a large camera that needs interchangeable lenses? Do you want a camera that you can toss in your purse or pocket? It's important to understand what your photographic needs are before you spend any money on a camera!

Understand the basic features of your camera. Sure, you can spend a lot on a great camera, but if you don't understand the basic features like digital zoom, optical zoom, or you're not sure how to use the preset camera modes like action, landscape or portrait, you'll be wasting your money. Take the time to learn what each of these features can do for your photos before you buy and you'll be getting the most out of your digital camera right out of the box!

If you're ready to upgrade your digital camera or purchase your first digital camera, a brief course in photography can also help. Check your local community college or fine arts center to see if they have any offerings in basic digital photography.

How to Use a Laser Pointer safely

  Teachers and lecturers have used laser pointers for years to highlight key areas on charts and screens during visual presentations. Recently, with reduced cost of manufacturing, the consumer now has a variety of features to choose from, including different colors and styles. The visible range of a laser pointer can vary considerably depending on wavelength, output power and environmental factors such as background illumination and air quality.

   There are plenty of things you can do that are safe and fun with a laser pointer. As the old saying goes, “Safety first!” because nobody wants to get hurt, but don’t let that prevent you from being creative with your laser pointer.

Steps

1.Never point your laser at another person, especially their face.

2.Never under any circumstances look directly into the laser beam. Even if it is a low powered laser pointer, you don’t want to take chances with your eyes.

3.Always be conscious of and aware of reflective surfaces such as mirrors, polished metal or glass. A reflected beam can also harm your eyes.

4.Only use laser pointers in a controlled environment.

5.Do not let other people use your laser pointer unless they are fully aware of the dangers of laser pointers.

6.Laser pointer beams can go for miles so never randomly use your laser pointer outside.

7.When in doubt, use safety glasses. Most laser pointers sold commercially have an output of about 5mW. This is generally safe for your eyes, provided you do not look into the laser beam for more than a few seconds. Laser pointers with a higher output (especially green) should require laser glasses or goggles. SUNGLASSES AND WELDING GEAR DO NOT WORK. These simply make your pupils dilate, making it easier to cause damage! Remember that there is no price tag on your eyes, and to buy glasses that are calibrated to the colour of your laser. There are no universal goggles.

How to choose a good laser pointer

   Green laser pointers are the pinnacle in high-end laser light technology, thus they are more expensive and hard to get. Many laser companies may be found on Google, but their 'hand-made' laser pointers are really risky products. After all, a laser is never safe if you use it in wrong ways and if you use the 'wrong' ones, there will be hell to pay. If you want to buy cheap and guaranteed laser pointers, especially green laser pointers, do research on the manufacturer before buying.    Here are some tips on how to choose a laser pointer.

1、carefully observe the light spot in poor light, if there is specific flood light around the laser spot, it indicates that the lens failed;

2、observe whether the spot has a perfect solid dot;

4、if it is a low power laser pointer (20 mW or less),we just need to observe that whether the brightness of the laser beam projected will change from dark to light the laser light when the injection will become dark and light, it will indicates that the laser pointer circuit or LD have problems.

Why Choose Green Laser Pointer?

    Green laser pointer has got its wide applications in speech, business conference, lecture, teaching, astronomy, military, medical etc, which is really a perfect tool for presentation. In the former time, only red laser pointer is available while now green, yellow, violet, orange, blue laser pointers are all available in the market place. From the first appearance of 5mW green laser pointer, green laser pointer has become the most commonly used laser pointer. The bright and high visible beam, sensitive color and medium wavelength have made the green laser pointer become the brightest gadget among all series of laser crystals.

Highest Visibility With the Color Green

   The green laser is ideal because it is the most visible to the naked eye at low light levels.  It has been tested that for the same level of output the green laser beam always seem brighter at low light level. The human eye is most sensitive to the color green.  Ever wondered why the chalkboards at school or the stop lights are green.  They are designed that way because the eye is drawn towards the color green.  Studies have shown that the eye is 50x more like to seen green than any other color.  That is why when choosing a laser pointer you should always choose green.  What ever it is that you want to draw attention to, your green laser pointer will certainly attract more attention.

Home office must haves you may ignore

When you decide to work from home it is an exciting time. Some necessary things such as office desk, computer, comfortable chair, phone, printer, bookshelf you will not forget. But there are still some must haves you may ignore.

Lots of Space

    A big part of finding that comfort zone is having enough space. If you really want a productive home office, take some time to clean and get rid of everything that’s creating a suffocating feel in your office. If you’ve been using the area as somewhat of a storage room ever since your house movers dropped your items off, this will be a good time for you to organize everything.

A Small Refrigerator

When you’re in the middle of a conference call, the last thing you will want to do is put your clients on hold so you can go get a bottle of water. Keep a small refrigerator in the room so that you can have access to fruits and beverages without having to run to the kitchen. Working from home is all about eliminating distractions by any means.

Hang a Clock in Your Home Office

Once your office hours are set, don't forget to hang a clock on a wall or place one on your desk - anywhere it is clearly visible. While this may seem laughable (or obvious) the truth is that when working from home, it is easy to forget about time. Before you know it, you have worked a 14-hour day, for the third day in a row. Even though your work is at home, there still comes a time when you have it to call it a day and shut your door to the office.

Brighten Your Home Office with Proper Lighting

When possible, choose a space for your office that allows plenty of natural light. Consider adding task lighting, or desk lamps and floor lamps that can give concentrated lighting to your specific work area. Besides, regardless of the type of lighting available, make sure that your computer screen is positioned so that it prevents a glare from occurring. The object is to create balanced lighting that minimizes eye strain.

Fruits and vegetables are packed with beneficial fibers, vitamins and antioxidants. They fill up your stomach fast so you feel full earlier. They are also low in calories and help to keep your calorie count low.

If possible, purchase fresh foods and avoid package (processed) and convenient foods such as fast food. Packaged and convenient foods are often higher in sodium and fat content.

Tip 6: Don’t be overly-restrictive

Everyone has his or her favorite treats. Simply allow yourself a little indulgence, but watch out for the frequency and the quantity. Having a small treat once in a while can be rewarding to your weight loss experience. Cutting too much of your favorite treats usually lead to an early relapse

A product labeled with a fat-free claim does not mean that it is low in calories. Similarly a product labeled as low-sugar does not mean it is low in fat or calories. Always read the nutrition label on the packaging.

Keeping a food journal helps you pin point your eating pattern and will enable you to easily modify it.

Tip 10: Exercise period

Most authorities recommend 30 – 60 minutes of physical activity a day to stay healthy. Also try adding weight-bearing exercises at least 2 times a week. This will help burn some of the unwanted calories.
