In 2010, Adobe released Photoshop CS5, making it the third version in three years. At the price they charge, that seems to be overkill. It is also the perfect example of why understanding the differences is key to saving money. The first difference is the addition of Touch Apps for anyone who uses a touch screen computer now. The apps used are iPad apps, making this a great tool to use if you work on a pad instead of a computer as well.
The workspace has continued to morph. Adobe including task-specific workplaces in Photoshop CS5 that you can switch between. This keeps you from having various tasks cluttering your main window and, with tabs, you can switch back and forth between the different tasks you are working on.
This version adds power to the editing tools, making the ability to remove elements and replace them with others easier than ever. The painting effects are also improved, allowing you to mix paint on the screen as you would in real life to produce the exact, unique colors you want. The Puppet Warp is a new tool that allows you to transform specific areas of the image while anchoring others in place.
3D effects continue to improve in Photoshop CS5 as you can convert 2D text and art into 3D objects and then work to inflate their surfaces. The 64-bit systems are also implemented in full and Adobe promises you can complete your tasks 10-percent faster. When looking at the Adobe Photoshop versions comparison, the best reasons to upgrade to CS5 is if you use an iPad or touch screen computer, or want the new 64-bit performance boost.
