How Has This Course Changed Your Perception of Digital Media This course has changed my perception of digital media by the amount of topics that relate to digital media such as the emergence of software to communicate content such as audio, video , and photos. Digital media is also constantly evolving and has changed the advertising industry and legacy media as a whole. I learned about the importance of file types and file sizes and how they relate to digital media. For example it’s important to know about the difference between a lossy file type and lossless file type. Lossy file types often lose data through compression and via data discarding to represent the data. A JEPG is an example of a file that will lose data because it is lossy. Lossless files preserve all the original data file has such as RAW, BMP and PNG files. They maintain their quality but there is a downside to these file types, which is the file size. They take up more space and they take longer to download than a lossy file would. This has changed my perception of the importance of knowing this information when it relates to quality of files I also learned that there are some aspects of legacy media that people can’t get through digital media such as the haptic feeling of touching a book or magazine cannot be replaced by digital media and some people even prefer it over e-readers and tablets.

Explain how print media (legacy media) has been impacted by the conversion to digital media. What have you learned regarding capturing and editing digital images, file formats, sizes and storage, has the lesson on digital video and digital audio changed your opinion on these two forms of “digital media”? Digital media has changed legacy media in many ways, such as the advertising industry and how ads are designed to capture consumers attention quicker, also with the rise of automation it has impacted digital media in a major way how ads are distributed(bought and sold) as well as how they are created using more statistical data along with more personal interaction with their customers through technology such as social media. Digital media expands though multiples devices such as computers, phones and tablets and websites , however books are far from gone due to people who still like the feel of a real book, the haptic feel of a book cannot be replaced by an a-reader and sometimes a book is easier to pick up and read. E-reader sales were down due to paper books being sold more. Something we also discussed is the use of geotracking and how advertisors now track people’s location to sell them products via their phone or mobile devices. With the rise of apps, automation, and geotracking companies can use this data to find locations you are around and remind you about products that may interest you based on things like your browsing history, places you may have visited before and use this as a form of advertising. One thing that is important in today's market is having goof SEO(Search Engine Optimization) in search engines such as Google to get good rankings when users search for products or services. Some examples of how this works are things like metadata which can improve your search rankin.

Explain how print media (legacy media) has been impacted by the conversion to digital media. What have you learned regarding capturing and editing digital images, file formats, sizes and storage, has the lesson on digital video and digital audio changed your opinion on these two forms of “digital media”? I learned what the difference between a file such as a RAW file and a file such as a jepg . It is RAW data that that can created to make s jpeg but it starts out as an unprocessed collected from the scene by the camera sensor. RAW files remain untouched and provide us a non destructive format to play around with our photos without destroying the original source. One thing to look far is that RAW images take up more space since the file size is larger and when you’re lacking in space on a memory card it is better to switch to jpeg because they files are smaller. I also learned more about storage, such as hard drive space and file sizes such as Kilobyte, megabyte, gigabyte, terabyte, and petabyte and there are larger sizes as well. 1024 bytes=1 KB 1024 KB=1 MB 1024 MB=1 GB 1024 GB=1 TB 1024 TB=1 PB I also learned that PDFs can play video, and audio. Acrobat converts the file to a format that be played by Adobe reader. One important thing I learned and can differentiate now is the difference between analogue and digital forms of media. How analogue is a continuous signals and digital will always be a finite set of information since it converted(quantization) to binary data. I also learned about Quantization which is a process of converting a range of input values into a smaller set of output values that closely approximates the original data. This applies to many forms of digital media such as audio and digital imaging.
