Introduction to digital camera parameters and purchase guide as titled Thank you

1. The size of the image sensor (CCD or CMOS), the important parameters of imaging quality, the larger the better, the clearer the imaging, the consumer-grade DC is generally 1 inch, and the full-frame SLR is 36 24mm. Low-light shooting is usually better than CCD, and back-illuminated CMOS is better than front-illuminated.

2. The focal length range, the minimum wide-angle end can reach 24mm, and the smaller the shooting range, the wider the shooting range; Look at the optical zoom factor at the telephoto end, use the optical zoom factor Wide-angle focal length = telephoto end focal length, the larger the vista can be pulled closer, and the current consumer-grade DC maximum optical zoom factor can reach 30 times.

3. The maximum aperture, the larger the low-light shooting effect, the better the background blur, the maximum can be reached at present, the small one is generally, the smaller the value, the larger the aperture.

4. Pixel, ** size parameter. It is worth noting that at present, many people choose cameras only to look at pixels, thinking that the higher the pixels, the clearer the shooting, in fact, the pixel has nothing to do with the imaging quality, it is just a parameter of image size, the pixel is high, if you want to put a large advertising poster, poster, choose a high pixel, otherwise you don't have to pursue pixels, large pixels instead occupy a large storage space, ordinary use 5-6 million pixels are enough.

The card machine is the kind of camera that takes the live view, and it is generally relatively thin and light, easy to carry, easy to operate, and cheap.

The single-lens reflex camera, formerly a single-lens reflex camera, is a professional-grade camera with high requirements for photography skills, and the imaging quality and shooting effect mostly depend on the technical level of the photographer. Its lens can be detached separately, and the lens and camera are very high, which is a necessary equipment for professional photographers. Canon's DSLR camera is the best performing and focused on it right now.

Telephoto digital is also the kind of live view camera, but without an external lens, it also has a large optical zoom (mostly more than 10x optical zoom), the operation is closer to the SLR camera, is the most cost-effective quasi-professional camera, that is, to meet certain performance operation needs, ** will not be very high.

Quasi-professional portable digital cameras mainly refer to telephoto models, the main characteristics of this type of models are large optical zoom, manual operation, function close to SLR models, shooting effect is partially determined by shooting technology, is the best choice for beginner photography enthusiasts to learn and exercise. Fujifilm's product reputation and cost performance are the best.

Wide-angle cameras are lenses with a shorter focal length and a larger angle of view. Wide-angle lenses can produce the effect of large foreground and small long shots. The image distortion produced by the wide-angle lens makes the objects in the foreground exaggeratedly magnified, making the foreground objects more prominent and giving a strong visual impact.

Household digital camera refers to the commemorative camera that meets the needs of general family travel and gatherings, and generally has the characteristics of convenient and simple operation, clear picture quality and rich functions.

Not to mention waterproof cameras, there are special waterproof cameras abroad to adapt to complex underwater shooting.

Recommend Panasonic FP8, beautiful, practical and cheap, because Panasonic does not care about the cost to use this machine to earn reputation.

FP8 has a wide angle, a relatively large aperture, and a high-cost ED lens that is rare in its kind, coupled with Panasonic's industry-first quality guarantee, and now Panasonic's new FP series is a performance downgrade and upgrade, which shows FP8's ultra-high cost performance.

The only drawback of the FP8 is that there is no lens cap, but there is a high-strength UV lens, and even some netizens took the key to swipe through the lens, which is not damaged at all.

In fact, in Japan, Panasonic is the first in the field of home cameras in foreign countries, and then Fuji (the general quality of the workmanship is generally cost-effective, and the F series has long occupied the title of the king of card machine image quality) Sony (the quality of the workmanship is good, the quality is generally technological innovation, but it is worth buying 2,000 yuan with a back-illuminated sensor, and the hardware defects of the battery lock jitter door are not changed), as for Canon, there are many advertisements in China, and there are many people, and it is expensive, not worth buying.

FP8 supply is not much, FP1, FH1 can be used as an alternative, the licensed goods of the machine plus spare batteries, memory cards are about 1300 yuan.

To put it mildly, when you buy a camera for 1,000 yuan, you don't need to pay attention to the parameters at all, and the appearance and quality are the most important. T and W are Sony's two series, and the low-end Sony has no purchase value.

1. ISO (sensitivity):

Definition: Sensitivity has a clear definition as early as the film era, which refers to the speed of the chemical reaction of the film to light, and the characteristics: the lower the sensitivity, the more delicate the image quality; The higher the sensitivity, the rougher the image quality.

The amount of light entering: The higher the ISO, the more light can be captured.

Speed: Higher ISO results in faster shutter speeds.

Image quality: Lower ISO results in more detailed image quality, while higher ISO quality results in higher noise.

Shooting traffic, light and shadow graffiti, etc.: 1 second, 1 2 seconds, etc. 2, BC (white balance):

White balance is responsible for color reproduction in shots, and the more accurate the white balance setting, the more realistic the color reproduction.

Aperture) controls the amount of light entering the lens.

The smaller the number, the larger the aperture, the more light coming in, the picture is brighter, the depth of field is smaller, and the background is blurrier.

Tricks: Landscapes (clear quality), small apertures.

Figures (in focus), wide aperture.

Shutter speed) definition: The time it takes for the shutter to open and close.

Handheld shooting: Do not fall below 1 to 60 seconds.

Shoot walking or fast moving: around 1,250 seconds.

Shoot traffic, light and shadow graffiti, etc.: 1 second, 1 2 seconds, etc.

Focal length): determines the size of the image, the size of the field of view, the size of the depth of field, and the perspective strength of the image.

The longer the focal length, the closer you are to the subject, the shallower the depth of field, and the blurrier the background.

Tip: The wider the aperture, the more noticeable the bokeh effect will be.

In good light, you can shoot with a sensitivity of ISO100 or ISO200 for better image quality. At night, in low light, or when you need to quickly capture the shape of an object, you need to increase the sensitivity to shoot.
