In twenty minutes I introduced participants to Photoshop and showed them some tools to touch up digital/digitized photographs on May 31st, 2011. Hopefully I’ve helped them get comfortable enough to play with all the different features Photoshop has to offer. I took this approach because it would be impossible to teach people about Photoshop in twenty minutes, a semester long class (like one that I’m took with UAA), or even a yearlong class. Why? Because Photoshop is one of the programs that has a multitude of tools and uses. Graphic designers are coming up with new and innovative ways to use these tools to create unique and amazing images every day. In the end, the user is only limited by their own creativity, time, and … patience 
There are an abundance of web tutorials online and so many ways to create one effect. Find the tutorials and methods that work best for you!
Below are some helpful links that can hopefully expand on my twenty minute training or may be of use to anyone who is interested in exploring Photoshop. Enjoy and have fun!

I would also like to show my appreciation to both my UAA CIOS 152 teachers, Katie Walker and Robert German. You’ve made learning Photoshop a joy! I’ve learned so much and excited to learn more.
