In the past 25 years, nothing has affected our perception of images more than Adobe Photoshop. By allowing users to adjust, fix, tweak and wholly invent images, the software has worked its way into our portfolios, our family lives and our media consumption.

Contrast that with what Photoshop can do now. While the video below shows just a few of the latest features, the software has become so absurdly powerful that a large part of the improvements have to do with helping you actually find and manage those features:

Of course, the power of the software still lies with the user who wields it; if you've got no sense of lighting, composition and scale, all the Photoshop in the world won't help you. Case in point, this ham-handedly retouched photo of the more recent 90210 cast:
