What does a digital camera use instead of film?

Download it to the computer, you can shoot it again, or you can reuse it without buying it.

From the previous office tools to the current fashion toys, digital cameras have become one of the hot peripherals of computers. As a fashion toy, this word is not appropriate, because it is not as easy to buy and use as a mobile phone. Let me talk about my views on digital cameras.

Digital cameras are different from ordinary cameras and ordinary computer peripherals. First of all, a good digital camera is not a fool camera, or even a fool camera at all, which requires certain photography skills. Of course, a good digital camera will also have a fully automatic mode to ensure that novices can get started, but it is a bit wasteful to buy an expensive digital camera just by using its fool function. At the same time, digital cameras can't be played well with certain photography skills, because users need to have a certain understanding of the post-processing of cg animation, otherwise there is no need to use digital cameras. After all, optical cameras (actually translated from abroad should be called film cameras) are still much cheaper and more mature in all aspects.

To sum up, if you just play with toys and your quality has not reached the professional or quasi-professional level, you'd better not buy them, or buy the products with the lowest price. Here is a product recommended, which used to be a fashionable toy for Japanese young people, the C-900Zoom of Olympus. See below for details.

1.3 million pixels, supporting uncompressed image storage, 35- 1 10 triple optical zoom, completely fool mode, just like the μ series of about 2000 yuan, the price in Hong Kong seems to be no higher than 4000 Hong Kong dollars. You can ask yourself specifically. It seems less than 5000 yuan in Shanghai. How to buy a digital camera? If it is used by the company, you can generally buy Kodak products, which are more expensive and of average quality, but suitable for office use. The best product at present is DC290. Note that DC280 is an improved version of DC240, with a 2x optical zoom, while DC290 is an improved version of DC265, with more than 2 million pixels and a 3x optical zoom. If you have seen the price of Kodak Fool and compared it with the price of Olympus, you will know the quality and positioning of Kodak. As for Kodak's professional cameras, it is another matter to use Canon and Nikon's bodies, but the price is not just zero. Because it is used in the company, the requirements for cameras are generally not high. Kodak supports USB and infrared data association, so it is more suitable. I think it's ok after using it. Apart from the ugly appearance and poor picture quality, I can't find any other shortcomings, but the lack of special batteries after entering China is really a headache. Don't forget to buy eight nickel-hydrogen rechargeable batteries, otherwise you can't take a few photos even with alkaline batteries.

As for my personal digital camera, I'm not stupid. What do you think of the following photos? This is a cool photo of a digital camera.

If the digital camera is for personal use, it certainly needs such a cool appearance and extraordinary performance. Support optical zoom, at least 2 times, digital zoom as an ornament. It has an excellent optical lens group, not ordinary lenses, including more than one aspherical lens. Of course, the size of the lens is also very important, which is reflected in the final aperture size, at least f2.8, the zoom range at least 35- 1 10, and it is best to support 28 mm. You can choose to adjust the shutter and focal length automatically or manually, with exposure control and white balance. Of course, manual plus autofocus is absolutely indispensable. The pixel of digital camera depends on the final effective pixel of actual CCD. Some digital cameras, which claim to be 2 million pixels, use AGFA or similar image interpolation technology. In fact, they only have 1.3 million pixels, so we must pay attention to it. If it exceeds 1.5 million pixels, the printed photos are almost the same as those of ordinary optical cameras, while the performance of cameras exceeding 2.5 million pixels can be said that it is impossible to make cameras with such high pixels without special lenses, which has exceeded the effect of ordinary optical cameras. Some brands use the famous Chas lens or proprietary Fuji Dragon lens, Olympus lens and Canon's own lens.

The main memory cards are smart media and compact flash memory. In fact, there is not much difference between the two. SM card is 32M at most, but it is cheap. With the popularity of MP3 players (SM cards are also used), the price will be cheaper, while CF cards are up to 96M, but the price is higher. Other storage methods include floppy disk (Sony), which can't store large-capacity graphics, and the speed is slow, while the price of memory chips is relatively high, but the maximum capacity can reach 64M. IBM's small hard disk, at least 120M, is also very small, but it seems that only Canon's high-end products can support it, Clik of Image! 40M capacity is also a new choice. Panasonic seems to have introduced LS- 120 digital camera. The main factors that affect the memory card are capacity, speed and price, and it is not possible to unify the three at present. I will introduce related articles in another article.

There are many ways to send data back to the computer. The slowest but most compatible is serial port, USB and infrared data association will be popularized soon, as well as PC-card and parallel port. It is better to have USB, because it is much faster. As for the TV function, I personally don't think it's necessary, because you can use a computer at home, and a 17-20 inch computer monitor is not better than a TV?

Power supply is also a great choice. If your digital camera uses ordinary batteries or alkaline batteries, you will find that your digital camera is a big spender, because it is necessary to change batteries for taking a few photos, so it is an inevitable choice to use rechargeable batteries. However, when entering China, I don't know where the problem lies, and often the standard accessories become optional accessories. But money can't be saved. I used 1650 mAh No.5 Ni-MH battery pack, and the effect was very good. Generally, the original battery has at least 1 150 mAh, because digital cameras are big power consumers after all.

And accessories? Of course, if you choose a high-end civilian camera, don't forget to buy a matching flash. I mean the auxiliary flash used when it is more than 3 meters. Some brands can use ordinary flash, but remember to match them, otherwise they will not be synchronized. Switching bayonet, the bayonet of digital camera is not standard. Only by buying a special bayonet can you use the filter and lens group of optical camera. If you have a wide-angle lens and a telescope head, you can also buy them together, because they can be much cheaper together.

The following are excellent products with performance close to that of professional cameras. There are mainly Olympus 2000Z and 2500l, Sony DSC-D505/D770, Toshiba M5 and Fuji MX-2900. These digital cameras with more than 2 million pixels are the best civilian products at present, and the price is basically around 6,543,800 yuan.
