Yes, it’s still the program that just about every photographer and designer on earth uses to retouch or even reimagine photos. It’s still the only program whose name is a verb.

But now, Photoshop is also the biggest-name software that you can’t actually buy. You can only rent it, for a month or a year at a time. If you ever stop paying, you keep your files but lose the ability to edit them.

You have to pay $30 a month, or $240 a year, for the privilege of using the latest Photoshop version, called Photoshop CC. Or, if you want to use the full Adobe suite (Illustrator, InDesign, Premiere and so on), you’ll pay $600 a year.

The price list is stunningly complex. The fees may be higher or lower depending on how many programs you rent, whether you already own an existing version and which one, whether you commit to a full year or prefer to rent one month at a time. There are also discounted first-year teaser rates, student/teacher rates and a 30-day free trial.

But you get the point: the dawn of Software as a Subscription is now upon us.

Microsoft is conducting a similar experiment with the latest version of Office. An Office 365 subscription is $100 a year. But there’s a big difference: renting Office is optional. You can still buy it outright if you prefer.

It should be obvious why Adobe is enthusiastic about rental software. First, it’s big money.

Not everybody will pay more than before under the new plan. If you use three or more Adobe programs and you upgrade to the latest versions every year, you’ll save money by renting.

But if you use only one or two programs, you’ll pay much more by renting — especially if you were in the habit of upgrading only every other year, for example. Here’s the math: Photoshop CC alone will cost $240 a year. In the old days, buying the annual upgrade cost $200, and you didn’t have to upgrade every year. In three years, you might have spent $200 or $400; now you’ll pay $720.

And Adobe could raise the rental prices at any time. Every year, if it chooses.

Adobe also benefits because a rental plan helps it cut down on software piracy. Despite its name (CC stands for Creative Cloud), the new software versions are not, in fact, stored online. You still download Photoshop, Illustrator and the other programs and run them from your computer. But the downloaded software checks in with the mother ship every 30 days, over the Internet, to make sure the subscription is up to date. If not, you’re locked out.

Finally, Adobe benefits because it’s no longer committed to a difficult, relentless annual release cycle. There will no longer be a big new version of each Adobe program each year. Instead, Adobe says that it will regularly slip in new features as soon as they’re ready. The company hasn’t decided whether it will ever use numbers again (Photoshop CS4, CS5, CS6), but for now, the name is simply Photoshop CC.

So far, the switch to a rental-only plan may sound like a rotten deal for many creative people, especially small operators on a budget. And, indeed, many of them are horrified by the switch. A touching but entirely hopeless petition ( has 35,000 signatures so far. (“We want you to restart development for Adobe Creative Suite 7 and all future Creative Suites,” it says. “Do it for the freelancers. For the small businesses. For the average consumer.”)

Adobe, however, points out that rental customers gain vast advantages over the old “you buy it” system. The big one, of course, is that perpetual refinement principle. You’ll always be up to date with software that’s constantly improving.

Adobe also points out that subscribing to Photoshop gets you more than just the right to download the software. The subscription comes with access to Behance, an online portfolio where you can display your Adobe-created documents and read admiring comments from fellow creative types. You also get 20 gigabytes of online storage for files, Dropbox style, so you can work on them wherever you happen to be.

Another perk: As before, you can use your rented programs simultaneously on two computers — but now, one can be a Mac and one can be a Windows machine.
