Abobe Photoshop is a powerful image editing tool, the standard in the industry. It is widely considered to be the best program for the purpose, beating out a number of competitors. Photoshop comes with a wide array of versatile and useful features.
Unfortunately, these very features can be confusing and bewildering to the new user. Attempting to learn to use this tool from the manual can be difficult and frustrating. Manuals are usually written as reference for users who already have an idea of what they are doing, rather than for beginners.
Even books on the subject seem dense and hard to understand. There may be many features in your copy of Photoshop that you don't yet know how to use, because of the difficulty of learning this complicated program on your own.
To harness the potential of Photoshop in your image editing, consider making use of movie tutorials. This type of tutorial allows you to see how a given feature is used or effect is accomplished in real time, as the action is performed. You can even stop the video to go try it out in your own copy of Photoshop.
Because of the ability to stop, rewind, and replay scenes in video tutorials, you can use them as a constant reference. If you do not have time or money to attend classes and seminars, video tutorials can be a great help in learning to use your copy of Photoshop.
Some video tutorials are available for free, others require some payment for the effort that has gone into them. These latter type are more likely to be professional. The saying goes that you get what you pay for, and this is still the case with Photoshop tutorials. However, even the free type of tutorial can be useful.
