The Manufacturers

Application Procedure radiator paints and enamels If you're going to make repairs in the winter when central heating is included, then the first thing you need to make sure – the temperature conditions applied. Many enamels and paints recommended to paint radiators only when the system is off. Without considering this, you risk getting a yellowish coating (if the stain alkyd white enamel) and not very flat and smooth (the paint will dry too quickly and unevenly, and no time to spread evenly). Surfaces must be clean, dry, without a trace of dust or grease. Unpainted radiators should be degreased, lightly treated with sandpaper and remove dust, covered with a layer of anticorrosive primer (primer CS-010) (usually the manufacturers operating instructions for recommended primer, which is best way combined with this paint). If the radiator has been painted previously, but the paint layer is in bad shape (cracked, flaking, etc.) then you should delete it and continue to do both with unpainted radiator.

If an old coat of paint and strong you are not satisfied only by its color or appearance, you should only treat the surface lightly with sandpaper to a state of haze and then wash it in any detergent removing grease and dust. Radiators are painted with a brush, paint the flat radiators comfortable cushion (less likely to use spray gun – it's less convenient) in 1-2 layers. On the wrist, by the way, need to be concerned in advance – depending on on what you have installed the radiator – may be the most convenient brush on a long handle, or, conversely, a small, thick or thin. For painting hard to reach places handy special radiator brush with a curved handle. If you apply two coats of alkyd enamel, after the complete drying of the first layer it is recommended to treat lightly with sandpaper.

CMOS Sensors

Greater the number of megapixels is only due to a special use in the professional field, and such models do not come to market consumer-grade digital cameras. Image quality with such a resolution is quite enough to create a beautiful family albums. Also, in the amateur segment will emerge with the type of camera CMOS sensor (CMOS), but consider this standard is not worth it, most likely, this type of matrix will increase the cost apparatus and will not affect significantly the quality of the images. Optical stabilization was necessary function in the last year and the year this will strengthen its position in all segments of the amateur cameras. Also, almost All cameras will be used double stabilization – a combination of optical and digital. Optical zoom (zoom or zoom) lets you zoom in far away from you and make a better picture.

On Today almost all the cameras are equipped with optical zoom, the most inexpensive models, he makes a threefold increase in focal length, some amateur models he reaches 12. Many Manufacturers also has a function of the digital zoom, ie increase due to mathematical treatment (approximation), but be aware that when you use it unambiguously deteriorates the image quality. In our look at this year's most in demand are cameras with 10 – 12 x optical zoom camera with zoom from 3 to 10-s well worth your attention, but to a lesser extent and it is more likely due to cost savings. Size display in 2009, also ceases to grow, because further increase the size of the display is simply not the size of the camera. Thus, manufacturers face a choice either to produce a compact digital camera with Display 2.7 '- 3.0', or increase the size of the chamber simultaneously with the display.

The second option will likely not become a mass phenomenon, because compactness of the camera is still very strong argument for his choice, especially if it is of rest, when you do not want to take a not that big machine, extra towel does not always capture. So the ideal size of the display in 2009 will be equal to 2.7 '- 3.0'. Please note that many manufacturers this year Announce cameras for outdoor activities or cameras strength. Moreover, active recreation can not only be on the hot beach, but in winter the ski resort. They are waterproof, impact-resistant and dust-protected, they can withstand cold and heat and controlled by taps and claps on the case. While in the past for the camera with these characteristics come up with a special cover, now the design is absolutely no damaged and the camera looks as stylish as usual and no extra features. Of the novelties of this format, we note 12.1-megapixel Canon PowerShot D10 and Olympus TOUGH-8000 and 10 megapixel Olympus TOUGH-6000.
