Creative Cloud libraries allow you to share and use assets (colors, styles, graphics, etc) across Creative Cloud apps.
Creative Cloud libraries can be shared with others.
Your cloud libraries, fonts, etc. sync across your computers.
What Do Creative Cloud Apps Do?
Photoshop
The industry-standard photo editing & graphic design app.
It’s extremely versatile and used across many industries: web, video, print, photography, etc.
Improve photos with retouching, color correction, compositing (putting multiple photos together), and so much more.
Create designs for social media, web, print, video, and more.
Create animated GIFs for email marketing, social media, etc.
Design graphics and animate them in After Effects.
Edit videos for social media, ads, marketing, TV, movies, etc.
Import video, music, sound, voice over, graphics, then put them into a timeline (sequence) and edit out the unwanted parts to create a compelling final video.
In Premiere Pro you can add effects such as removing greenscreen backgrounds, but for more complex things, consider using After Effects.
A new generation digital design tool used to design the user interface (UI) and user experience (UX) of digital products such as websites, apps, and more.
XD competes with similar apps from other companies such as Figma and Sketch.
You can get started with a free plan, but there are limitations. Paid plans do not have those limitations.
You can animate directly within Adobe XD, and there’s an export to After Effects for more complex animations.
Lightroom Classic is the original Lightroom app which many pro photographers use.
Lightroom is a newer simplified app which requires your photos to be stored online (in your Creative Cloud storage).
Lightroom Classic works with photos stored locally. You can sync selected photos do access them via the Lightroom mobile app (for iPhone, iPad, & Android).
