How to pick a digital camera?
optical zoom and digital zoom What is the difference? Optical zoom is the real pixel, and digital zoom is at the expense of the quality of the cost of the photo,
so the image is more beautiful and beautiful. Home camera, not too much CCD, 500 million -800 pixel camera, 1 / 2.5 inch is enough.
In theory, the larger the CCD size, the better the effect of collecting light, the more information recorded on the screen, the more detailed the more detailed
Pixel level and imaging clarity is not particularly large relationship Oh! Remember: too high pixels will only waste your storage resources!
?Family with the camera, 500 million -800 million, is to use the effective pixels!
