week7

This week we had our last digital media lecture for this teaching block. It makes me a bit worried, because there were useful tips in the lecture, which I did not know so far. In this lecture we had a look at various methods of using and working with digital media files. We learned about formats and techniques of digital media files.

Digital media files could be: images, videos, audios and texts.

We talked about analog and digital media files. Analog photography means anything which is not digital, which is usually chemical process based. 15 years earlier digital cameras were rare, instead of it, people used to take photos with their analog cameras on ceremonies and family occasions. These analog cameras worked with a different process like the cameras nowadays. These images had to go through a chemical process in order to see the photos. During this chemical process the photographic film and paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.

There are ways to convert analog photographs to digital ones. In this lecture our teacher showed us some pictures about the conversion. Here are some:

In this lecture we also learned about analog and digital videos.

Analog video is a video signal transferred by an analog signal. An analog color video signal contains luminance, brightness (Y) and chrominance (C) of an analog television image. Analog video is used in both consumer and professional television production applications.

Digital video signal formats with higher quality have been adopted. Digital Video Broadcasting (DVB) uses coded frequency, this standard has been adopted in Europe.
