Before you hesitate upgrading to Adobe Photoshop CS4, take a look at this video and contemplate how far we’ve come in 19 years. (Yes Photoshop is 20 next year!) This is version 1.0 from 1990. The amazing advances from 1990 to today is one of the reasons I love what I do. (and you should too!). So sit back, take a relaxing breath and be happy that Adobe is coming out with better, faster, greater products for all of us to enjoy. Now go forth and upgrade.
Believe it or not, I learned Photoshop version 1! There was so little to it (although it took me awhile to remember what an alpha channel was) and I just learned all the new features as they were introduced. It’s hard to believe how complex it is now.
