How to Use Digital Camera

With the rapid development of digital technology, the functions of digital camera have increased dramatically. As today’s consumer digital electronics-digital camera is quite different from the traditional film camera, it’s necessary for us to have an overall look into the operation skills of the Digital Camera.

NO.1 .accurate white balance
The CCD or CMOS can’t act as the traditional film to indicate the color, so adjustment should be made to the color offset. Adjusting the balance of light color temperature to eliminate the color offset at utmost, that’s the so-called white balance.

There are five setup options of the white balance: auto, daylight, tungsten, fluorescent, incandescence. Because Auto can’t always perform well in any case, setup options can be used under different circumstances. “Daylight†is suitable for the sunny days outdoors; Tungsten is good for the cloudy weather, dusk and dawn time. “Incandescence†is suitable for the shoot under the incandescent lamp; “fluorescent†is suitable under the fluorescent lamp. Some digital camera even can self-define the white balance.

NO.2 click the shutter
A shot is finished by clicking the shutter, and it makes no difference to the digital camera. What’s different is that the digital camera has the functions of automatic focusing and auto exposure. It’s a two -step –shutter. First, focusing, metering and lock up. Second, the shoot. In the dim light, slight moving can affect the clearance of a photo. If possible, take a trivet to assure the stability.

NO.3 digital fill-in light
When we can only shoot towards the lights, the target will look dim and shadow may appear. You can click the “back light†and a better photo can be taken as you see the indicator in the LCD viewfinder. If your digital camera has no “back lightâ€, you can adjust the Manu aperture or take a white T-shirt as a temporary deflection plate.

No.4 memorizer of proper size
Most of the memorizer is external linked one or built-in and external lined one. The memorizer of different factories may be incompatible. CF, SD which can be read universally will be a better choice.

No.5 makes best use of the zoom
The big difference between the digital camera and traditional camera is the digital zoom. The current digital camera not only has the 2-5 optical zoom, but also has 2-10 digital zoom. When you take photos with optical zoom, special attention on the distortion level on the framing edge is needed. In order to avoid the deformation, you can try to move the target in the centre of the picture.

Digital zoom is to larger the pixels size with the help of the camera processor. It will lower the quality of the picture. Sometimes if the target is far from you, you can take the high definition saving model together with the digital zoom. You can take an impressive close-up shot in a direct way. Just as mentioned above, if a trivet is utilized, there will be less chance to see the vague pictures caused by the moving.

Do you understand the above technique? Then adopt them to practical picture shooting! I do believe it is not only useful to the entry-level digital camera users! Have not gotten a good performance digital camera? Why are you still hesitating? Don’t you want to write down your wonderful moments and keep your memories? You do have full reason to own one! Now, open your PC and enjoy the tons of choices showed before your eyes provided by wholesale electronics suppliers around the whole world.

What is a good digital/electronic piano for under $1000?

I'm interested in buying one for my bedroom, where I can practice with headphones on (and not disturb anyone). I'd like to eventually be able to hook it up to my computer to record music - via USB - and I sort of prefer weighted keys over non-weighted ones because the feel is closer to that of a real piano. Thanks!

Yamaha products are best. Look into the digital pianos available at your local Music and Arts store. I am a piano teacher and severalof my students have purchased their's at Music and Arts. Many stores are having big after-Christmas sales right now, too!
Here is a link so that you may find a store near your area: http://www.musicarts.com/locations/

Good luck!
