Screening : Mission to Earth

In digital cinema , non-existing objects can appear in the scene . This is totally different from the traditional cinema because the traditional one can only appear the existing objects . In "Mission to Earth", the digital effects are created by the editor . They do not appear in the reality . Therefore, the digital cinema can enhance the atmosphere by creating these digital effects . For me , this is a progress of the traditional cinema .

The screening remind me of the painting of George Seurat . He had claimed that the pointillism in painting . That means if the painter puts two different color on a paper , the viewers will mix up the color by themselves . For example , put red color next to yellow color , green color will appear on the viewer's eyes. In "Mission to Earth", the editor put the digital effect and the story scene next together . It may implies that the viewers can mix up two scene together in order to enhance the atmosphere of the context of story .

Digital photography and camera

Digital technology helps us to achieve many photographic effects .We can amplify or lessen the pictures as our preference. Also, we can regulate the brightness , roughness of the pictures when we use the digital technology . On the other hand , we can add objects into the picture which the object doesn't appear on the picture .

However , some photographic techniques can only be done by using the digital technology, such as adding some objects into the pictures . We would like to add some objects into the pictures in order to make the picture more meaningful . For example, someone takes a picture of the sky . He may puts a angel under the sky which makes the scene implying the angel coming from the heaven. Also, the digital technology can help sharpen the facial expression of people .

Analog photography is limited by the surroundings so it is less flexibility . Digital photography exists a high degree of flexibility . It can be regulated according to human preference .

Will wikipedia mean the end of traditional encyclopedia

I do not admit that the wikipedia mean the end of traditional encyclopedia . They are two similar but different manners . Wikipedia is a way of quick searcher and the refreshing speed is fast . Traditional encyclopedia is a way of detail researcher and the refreshing speed is much more slower . But it is true that the usage of wikipedia is highly greater than the traditional encyclopedia , it doesn't mean the end of the traditional one . Because it depends on the object of the searcher . Wikipedia provides a convenient way and basic background to the searcher . Traditional encyclopedia provides a detailed and fruitful information to the searcher .  

Disscussion : Evaluating the effects of new technologies

In " Modern Times" , it showed that the new technologies enhance the speed of producing a product . For example, the transporting belt helped saving the time of transporting the product from one process to the next process . Under the invention of new technologies, all human beings gain from it . To the wealthy people , they can invest on it and gain a big profit . To the grass root , new technologies make a great convenient to them . To the worker, the working machines save their time and physical consumption . In Modern Times , the transporting belt help eliminating the process of transport the semi-finished product from one place to another place .

However, the new technologies may not under control all the time . In modern Times , the main character suffered from the feeding machine . The function of the machine didn't appear and it also delayed the working time .

Nowadays , computer and internet dominates most of the entertainment . I , as a normal student also addicted to this unreal world . That is not a good situation .
