New Photos app for OS X coming soon (pictures)
The new Photos app coming this spring sports a familiar layout with easy to use editing tools.

Apple's Photos app
Apple's Photos for Mac OS X Yosemite combines an iOS-like interface with advanced editing tools familiar to desktop users. CNET takes a closer look at the developer release.
Familiar interface
If you're an iOS user, you'll recognize the layout of your photos that lets you switch between moments, collections and years.
Albums view
When you look at the Albums view you'll have all the albums you've created at the bottom, with ways Apple has designed to help you find pictures at the top.
Faces
iPhoto users will recognize the Faces feature that picks out people in your images and groups them together so you can find them.
Projects
Apple gives you a number of things you can do with your images under the Projects tab.
Create a new project
Click the plus sign in the upper right to create a new project. You can make holiday and gift cards, photo books, calendars and more.
Adding Filters
The Photos app doesn't come with very many filters, but all are high quality from what I've seen.
Adjustments
These easy sliders for adjusting brightness, colors and other attributes hide all the actual adjustments made to your photo. You can click the arrow to the right of the heading to get the specific adjustments being made.
Auto level and crop (1 of 2)
Not every picture is perfect. Sometimes you take a photo at an angle and while you can manually rotate it, it often leaves gaps at the top and sides.
With the Photos app, you can click the Auto button in the lower right to automatically make it level and crop the gaps out for a perfect image.
