Adobe makes some of the most powerful graphics tools available, such as Photoshop and Illustrator. Photoshop is by far the most popular tool for graphic designers and hardcore photo editors, but it isn't Adobe's only photo tool.
Adobe also makes a program called Lightroom, which is just the photo editing features of Photoshop. It's a nice streamlined experience for people who don't need Photoshop's mountain of graphic design tools.
Lightroom is also useful for organizing photos and syncing them across your gadgets, from your computer to the Web to your mobile gadgets. Yes, Adobe has a Lightroom app, and now it's free for Android users (it's been free for Apple users since October).
The Lightroom app lets you edit your photos however you want. You can use one-tap automated tools for making common corrections, or take full control of every aspect of the image. Edits you make to one photo can be copied to other photos for fast consistency.
Lightroom handles RAW files, and even lets you shoot RAW files with your smartphone or tablet camera. Learn the benefits of shooting RAW photos.
The free version of Lightroom lets you edit photos on your mobile gadget. If you want to sync your photos up with your library on your computer you will need a subscription to Adobe's Creative Cloud, which start at $9.99 a month.
