So what is a digital SLR, anyway? The term digital SLR is short for digital single lens reflex, so named because these types of cameras use a mirror positioned behind the camera lens to direct light toward the viewfinder when you're composing a photo. When you release the shutter, the mirror swings quickly out of the way, letting light from the lens travel straight to the sensor and momentarily blacking out the viewfinder. The viewfinder in an SLR incorporates a prism--usually a pentaprism--that flips the incoming image around so that you can see it right side up and bounces it onto the focusing screen where you see it. The SLR design allows one camera to accommodate a very wide range of lens focal lengths, and that's the biggest reason that SLRs dominate serious photography. The explanation? With a non-SLR camera, you have to match the angle of view of the "taking" lens with that of the "viewing" lens. That's easy with a fixed lens or a short-range zoom, but it requires increasingly complex and expensive viewfinder mechanisms as you try to cover a wider range of focal lengths. With an SLR, you avoid this problem because the taking and viewing lens are one and the same. Most dSLR models beyond entry-level models incorporate a Live View mode, which allows the photographer to use the LCD to compose shots the same way they can with a snapshot camera. The most basic implementations generally lock up the mirror, with the prism diverting the image to a small sensor that feeds through to the LCD rather than to the capture sensor. This does tend to hurt performance, however. Early versions required that you focus manually when in Live View mode, but current models use contrast autofocus. Types of digital SLRs Types of digital SLRs Nikon D300 Interchangeable-lens full system digital SLR These are what most people mean when they say "digital SLR," and they are the primary focus of this buying guide. As the name implies, the capability to remove one lens and replace it with another--to go from, say, ultra-wide-angle to supertelephoto--is what sets these cameras apart. Examples: Almost all of the digital SLRs available today are of this type. Here you'll find reviews of the entry-level, prosumer, and professional models that we like best. Olympus E-20N Fixed-lens digital SLR The lenses on these cameras can't be removed, which limits their versatility. The best known of these models use a semitransparent, nonmoving mirror to bounce some light to the viewfinder while letting most through to the sensor, which means you can use their LCDs for composing. Examples: Olympus E-20N Canon PowerShot S5 IS SLR-like or SLR-style These are standard digicams that use an electronic viewfinder (EVF)--just a small LCD--in place of an SLR's pentaprism or a point-and-shoot's optical finder. They can't truly be considered SLRs because they have no mirror, and we've yet to see an EVF that approaches the image quality of a decent pentaprism viewfinder. Most cameras of the type have extremely long zoom lenses and cameras are sometimes referred to as ZLRs or megazooms. Examples: Megazoom Panasonic Lumix DMC-G1 Interchangeable lens cameras Also referred to as Hybrid cameras, these are models which use the same technology as point-and-shoots, but incorporate an interchangeable lens mount. The first "standard" to emerge in this market is the Olympus/Panasonic Micro Four Thirds joint technology venture. Like SLR-style cameras, they use an EVF, since they lack a mirror for an optical through-the-lens view.

You should know compact flourescent light bulbs

compact Fluorescent Light Bulbs What Consumers Need to Know Compact fluorescent lamps (CFL) are small fluorescent light bulbs that use up to 75 percent less energy than a traditional incandescent bulb and can be screwed into a regular light socket. Switching from traditional light bulbs to CFLs is an effective, accessible change every American can make right now to reduce energy use at home and prevent greenhouse gas emissions that contribute to global climate change. Lighting accounts for close to 20 percent of the average home’s electric bill. Changing to CFLs costs little upfront and provides a quick return on investment. If every home in America replaced just one incandescent light bulb with an ENERGY STAR qualified CFL, it would save enough energy to light more than three million homes and prevent greenhouse gas emissions equivalent to those of more than 800,000 cars annually. As consumers look for ways to conserve energy, save money and help the environment, use of these light bulbs is increasing. Unfortunately, some of the properties that make these bulbs energy-efficient can also cause concerns in other areas. Ohio EPA developed this page and associated fact sheet in an effort to increase the public’s awareness of these issues, and ensure that consumers have information they need to make an informed decision about the use and ultimate disposal of CFLs. What’s the issue? What should I do if I break a bulb? How should I dispose of unbroken or burned out bulbs? I broke a bulb awhile ago and have questions about whether my family and home are safe. What do I do? Helpful Links What’s the issue? CFLs contain about five milligrams of mercury (roughly equivalent to the tip of a ball-point pen) sealed within the glass tubing. By comparison, older home thermometers contain 500 milligrams of mercury, and many manual thermostats contain up to 3,000 milligrams. It would take between 100 and 600 CFLs to equal those amounts. Mercury is an essential, irreplaceable element in CFLs and is what allows the bulb to be an efficient light source. Mercury is an element that, if breathed and absorbed by the body, can cause neurological damage. The U.S. Environmental Protection Agency and the U.S. Department of Energy assure us that CFLs are safe to use in your home. No mercury is released when the bulbs are in use, and they pose no danger to you or your family when used properly. However, CFLs are made of glass tubing and can break if dropped or roughly handled. Be careful when removing the lamp from its packaging, installing it or replacing it. Ironically, CFLs present an opportunity to prevent mercury from entering our air, where it most affects our health. The highest source of mercury in our air comes from burning fossil fuels such as coal, the most common fuel used in the U.S. to produce electricity. Energy-efficient CFLs present an opportunity to prevent mercury emissions from entering the environment because they help to reduce emissions from coal-fired power plants. A CFL uses 75 percent less energy than an incandescent light bulb and lasts up to 10 times longer. A power plant will emit 10 milligrams (mg) of mercury to produce the electricity needed to run an incandescent bulb compared to only 2.4 mg of mercury to run a CFL for the same time. That means that use of the CFL will actually prevent six to eight milligrams of mercury from entering the environment. What should I do if I break a bulb? The risks to you and your family from breaking a CFL are small. The amount of mercury in a CFL is very small, about five milligrams, or the size of the tip of a ball point pen. In comparison, older thermometers contain about 500 milligrams of mercury. It would take at least 100 CFLs to equal the amount of mercury in a single thermometer. The mercury in a CFL is needed to help turn the electric current into white light you get from the bulb. Once turned on, a very small amount of the mercury in the CFL becomes a vapor. If a CFL bulb breaks, a small amount of the mercury vapor will be released in the air. Unlike the elemental mercury found in fever thermometers, which are the shiny beads of liquid mercury, you will probably not see any mercury with the naked eye if you break a CFL bulb. The white powder you see is from the phosphorus coating on the inside of the CFL. So if you break a bulb, you’re at little risk for significant mercury exposure. It is important, though, to carefully clean up and dispose of a broken CFL to avoid spreading around the phosphorus powder, glass and any remaining mercury. Here are U.S. EPA’s guidelines for cleaning up a broken CFL: Open a window and leave the room (restrict access) for at least 15 minutes. If you have fans, place the fans in the windows and blow the air out of the room. Note: If the room has no windows, open all doors to the room and windows outside the room and use fans to move the air out of the room and to the open windows. Remove all materials you can without using a vacuum cleaner. Wear disposable rubber gloves, if available (do not use your bare hands). Carefully scoop up the fragments and powder with stiff paper or cardboard. Wipe the area clean with a damp paper towel or disposable wet wipe. Sticky tape (such as duct tape) can be used to pick up small pieces and powder. Place all cleanup materials in a plastic bag and seal it, and then place in a second sealed plastic bag. If no other disposal or recycling options are available, private residents may dispose of the CFL in residential garbage. Be sure to seal the CFL in two plastic bags and put into the outside trash. Wash your hands after disposing of the bags. The first time you vacuum the area where the bulb was broken, remove the vacuum bag once done cleaning the area (or empty and wipe the canister) and put the bag and/or vacuum debris, as well as the cleaning materials, in two sealed plastic bags in the outdoor trash or protected outdoor location for normal disposal. I broke a bulb awhile ago and have questions about whether my family and home are safe. What do I do? If you took the proper steps to clean up a broken CFL in the past, as described above, you are probably at little risk for any significant exposure. If you are still unsure, however, your health department is the best place to get information about indoor air quality and health-related risks from mercury. You can contact the Ohio Department of Health (ODH), Bureau of Environmental Health, if you have questions about health risks related to mercury. E-mail Greg Stein, ODH, or call him at (614) 466-1390. How should I dispose of unbroken or burned out bulbs? Like paint, batteries, thermostats and other hazardous household items, CFLs should be disposed of properly. Do not throw CFLs away in your household garbage if better disposal options exist. If under warranty, return it to your retailer. ENERGY STAR qualified CFLs have a warranty. If the bulb fails within the warranty period, return it to your retailer. Recycle it. U.S. EPA recommends that consumers take advantage of local recycling options for CFLs where available. U.S. EPA is working with CFL manufacturers and major U.S. retailers to expand disposal options. For more information, go to: Home Depot – National in-store, consumer compact fluorescent light (CFL) bulb recycling program Ohio Consumers’ Council CFL bulb disposal Manage it with other household hazardous waste. Many communities and solid waste management districts (SWMD) hold household hazardous waste collection events. You may take CFLs to these events to be disposed of along with other household hazardous waste such as leftover paint and chemicals. If your county isn’t listed, there are some companies who will take CFLs from residents for a fee. The charge is typically between $0.25 and $0.70 per bulb – with 50 cents being the most common. Ohio EPA does not endorse these companies but is merely providing their contact information to assist our customers. Place it in sealed bags in outside trash. If you can find no other disposal option, private residents may place used CFLs in their household garbage. Be sure to seal the CFL in two plastic bags and put it into the outside trash. Do not dispose of CFLs in an incinerator.

my first compact fluorescent lamp Apr13 My family is very poor, our electricity is only 450 W. we have television only, a compact fluorescent lamp for dinning room , incandescent bulbs for kitchen, and bed rooms. We didn’t have a lots of money even to buy more compact fluorescent lamp. when compact fluorescent lamp in the dinning room was out order we couldn’t buy a new one. so we use incandescent bulb again. Because we only have Television , everything is ok. I love learning on my own after finishing my senior high school .I learned English on my own seriously. I spent most of my days and nights sitting in front of my table studying English. Then I realized my incandescent bulb in my room ( where I studied ) no longer give me enough lighting and my parent kept telling me my 100 W incandescent bulb spent too much energy, so I made afford to buy a new compact fluorescent lamp ( I sewed embroidery for living too )as the shopkeeper in the shop where I looked for bulb that can give me more lighting recommended me a 15 W compact fluorescent lamp that lighter than 100 W incandescent bulb. so I bought it eventually and it helped me a lot.

it has been long time when I loved some one that killed me to the death. At that time my love didn’t set me blind to know he didn’t fill the requirement. He treated me unpolitely. it was years ago when I was a student of a senior high school at the last years. We dated 2 or 3 time when then I asked myself is he the man I looking for . I left him behind even my love was so big but I thought staying beside him just drive me to black hole. here I am now… live happily , after avoiding a big mistake, but I still wish some day there is a day I and he sitting together discussing why I left him, . he is probably not as bad as I thought. who knows

It's terrifying! Pick colors that are blah, and your house will seem flat and featureless. But if the colors you pick are too bold, they might overwhelm the architecture... and upset the neighbors. The best colors will highlight the most beautiful features of your home. Skillful use of color can even disguise design flaws, boosting the curb appeal and market value of your home. How do you find that magic color combination? Follow these tips. 1. Honor History If you're planning to paint an older home, you'll probably want to use a historically accurate color scheme. You can hire a pro to analyze old paint chips and recreate the original color. Or, you can refer to historic color charts and select shades that might have been used at the time your home was built. Photo: Historic Colors 2. Jazz Up the Past In some neighborhoods, homeowners fly in the face of history. Instead of choosing historically accurate colors, they paint their houses modern colors to dramatize architectural details. Using bright colors on old architectural details can produce startling and exciting results. But before you buy 10 gallons of bubblegum pink, it's a good idea to look at what your neighbors are doing. A fluorescent colored Victorian that looks splendid in San Francisco will seem wildly out of place in more conservative neighborhoods. Photo: Jazzy Colors 3. Consider Your Neighbors The house next door can give you paint color ideas, but don't copy your neighbor exactly. Choose colors that set your house apart, without clashing with nearby buildings. Photo: Colorful Cottages 4. Borrow From Nature The landscape around your house is blooming with color ideas. Trees may suggest an earthy palette of greens and browns. A beach setting might suggest vivid blues, turquoises, and coral colors. Even the garden in your front yard can inspire exciting color combinations. Photo: Nature's Colors 5. Check the Roof Your house is your canvas, but it is not blank. Some colors are already established. What color is your roof? Your paint color doesn't need to match the roof, but it should harmonize. Photo: Roof Colors 6. Look For Things That Won't Be Painted Every home has some features that will not be painted. Does your house have brick walls? Vinyl windows? A natural wooden door? Will steps and railings remain their existing colors? Choose a color scheme that harmonizes with colors already present on your house. Photo: Brick and Stone 7. Find Inspiration in Your Living Room It may seem comical to paint entire house based on the pattern of a pillow case, but this approach does make sense. The color of your furnishings will guide you in the selection of your interior paint colors, and your interior paint colors will influence the colors you use outside. Once again, your goal is to harmonize. Photo: Wright's Red 8. Focus on Details Depending on the size and complexity of your home, you may want to choose two, three, or as many as six colors. In addition to color for your siding, select accent colors for shutters, moldings, doors, window sashes, brackets, columns, and porch decks. But beware: too many colors will overwhelm your house. Too few can make your house seem flat and uninteresting. Photo: Detail Colors 9. Use Light to Add Size It's no wonder large, grand estates are often painted white. Light colors make a building look larger, and white is the favored color for traditional classical architecture. You can add to your home's sense of size and dignity by using white or a pale cream color. Photo: Classic White 10. Go Dark For Drama Dark siding or dark bands of trim will make your house seem smaller, but will draw more attention to details. Darker shades are best for accenting recesses, while lighter tones will highlight details that project from the wall surface. On traditional Victorian homes, the darkest paint is often used for the window sashes. Photo: Dramatic Accents 11. Discover Color Families Contrasting colors will draw attention to architectural details. But, extreme contrasts will clash and actually detract from details. To be safe, consider staying within a single color family. For some accents, try using a darker or lighter shade instead of a different color. Photo: Subtle Colors 12. Strike a Balance A burst of a single color on just one part of your home may give it a lopsided appearance. Strive to balance colors over the entire building.
