The Influence of Digital Technology on Traditional Photography

The fundamental difference between digital photography and traditional photography is that it is different from traditional photographic materials, and it does not need complicated chemical processes to form digital image files directly on CCD. Compared with traditional photography, it has the following advantages.

1, the traditional photographic materials are disposable and cannot be reused, but the CF card of digital camera can be reused, which makes the resources be utilized and is beneficial to environmental protection. As we all know, in the past photography, the attractive film cassette and packaging left for individuals was one of the risks of environmental pollution.

2. In traditional photography, images need a series of processing before they can be formed. Although POLAROLD next imaging camera produced by Polaroid Company can stand firm, the image quality is low, the cost is high, it is difficult to save, and it cannot be repeatedly developed, etc., and it has not been popularized. Although the digital camera is not enough, it is very intuitive, and the shot image can be displayed on the LCD panel immediately. If you are not satisfied with the preview, you can rename it as.

3. For photography, apart from the high mountains, it is worrying that all the hardships of the builders are the preservation and management of the film, for fear of film tide and film loss, sometimes in order to seek a kind of "film without feet". The storage and management of digital images are very convenient, as long as they are arranged, sorted and annotated, they can be done directly through the browser. Generally speaking, it's safer to keep it in the computer, if you burn the backup CD with peace of mind.

4. Traditional photography should be expressed, and a shot should be developed, enlarged, mailed, copied and printed. In order to facilitate printing, the photos taken by the digital camera can be directly delivered to the designated mailbox through the network to arrange the Bible, which reduces links and eliminates distortion. This is an easy advantage for news photographers, and news photography digital cameras beat traditional cameras, and the news unit rate of digital cameras is extremely high. In this year's Jose entries, digital entries also account for the majority, which is the performance of their advantages.

5. Although the traditional photographic materials have various sensitivities to choose from, the photographer's experience is all kinds of light, so it is unrealistic to change the film with different tones at any time. The film speed of digital cameras may be adjusted at any time to meet the needs of various light conditions. Generally speaking, the CCD ISO film speed of digital camera manufacturers is similar. According to the same standards, the film speed of ISO 100 CCD digital cameras is the same as that of ISO 100 ordinary cameras. In shooting, the ISO value can be changed according to the shooting needs, and the shooting effect of sunlight and lighting can be exchanged through white balance adjustment, which more effectively increases the photographer's shooting freedom under the conditions of light and lighting.

6. Digital images can be adjusted and modified by directly entering the computer. Traditional images must go through a scanner when entering the computer, and the scanning process affects the quality of the images. Many people think that the image quality of traditional photography is unparalleled with high digital imaging and low resolution digital cameras. This is true, but the image quality of more than 5 million digital cameras is basically no less than that of 135 traditional cameras.
