Adobe Photoshop is the program for professional photographers and designers. Although Photoshop offers a lot of features and gives you a complete photo editing package, it will only be effective for professional users. So why buy an expensive license key, when you can do the job done with a free one?
There are a lot of options and no.. - Microsoft Paint is not one of them. Pixlr for example is an ideal online copy of Photoshop. Very easy to handle and it is free for usage.
The beauty of Pixlr is that you can use the program all over world, because only access to the internet is required. You do not need the program to be installed on your computer. Pixlr is usable inside most popular browsers like Firefox ,Google Chrome or the Opera browser. Furthermore you have several efficient browser plugins available to make working with Pixlr even more pleasant.
Be certain to check out YouTube for numerous video courses that learn the way of working with Pixlr.
