It is easy to find a YouTube tutorial for Photoshop. Then, I open both the video and a Photoshop project on my Mac. That way I can start and stop the tutorial as I practice the new techniques.
I can also use my handy iPhone to reach YouTube. I can search for tutorials, or spend some time reviewing what is popular in all kinds of strange topics. Here's a really funny sketch about a "Man Cold".
My pictures here on the blog should improve as I learn new tricks. Getting the iPhone to look like it does over there took me much longer than I'd care to admit !!
