CS stands for Creative Suite. The CS2 is known to be the early version of this application. CS4 is known to be the newer version and it will allow the application to be opened in different Microsoft Windows types. This means that the CS4 is known to run better as compared to the CS2.
CS4 was also highly marketed. In fact, it was marketed in 6 editions so that it will work properly. The CS2 was only marketed in two editions. If the features of these two would be checked, you will see that the CS4 comes with a lot more features that people can use when using the Creative Suite.
When you look in magazines today and see celebrities, you may wonder if they look that great. Most likely, they do not look that great because they have been photoshopped. This means that after the photos were taken of the celebrities, the photos were uploaded into the computer. Then they were altered through photoshop to make the celebrities look better.
There are two types of photoshop applications, and they are CS2 and CS4. The first version is CS2, and the later version is CS4. CS2 was released in 2005 whereas CS4 was released in 2008. There are six editions to CS4 and two editions to CS2. Since CS4 is a later version, it also has more features to choose from than the CS2.
