In today's world, you are likely to purchase stock photography for your projects. It is tempting to download the .jpg provided and begin to reformat it directly for your projects. This is not recommended - and here's why. Every time you open and resave a .jpg, the information within it is diminished. You are literally throwing pixels away with every single save as command. Files formatted as .jpg have a lossy compression attached to them. This means the original data is not preserved. Lossless is a second compression system that preserves original data. Lossless files are larger, and that is why it is often not utilized, particularly online. Here is a short video that does an excellent job of explaining the difference between lossy and lossless compression. Notice how the narrator describes the different compressions and their effect. Much of what he explains will help you with this week's discussion.
