"Rick Sammon’s 50+ Tips for Nik Color Efex Pro" is actually three iPhone/iPad apps in one: 1) Illustrative app showing before-and-after examples of every filter in Nik Color Efex Pro; 2) An app with more than 50 photo tips; 3) Wallpaper app with more than 50 photographs that can be used as wallpaper for your iPhone and iPad.

The app is on sale for $0.99 until 5.1.13. After that the price goes to $1.99.

Photographer Rick Sammon, author of 11 apps (and 36 books), developed this text/photo app to show you the creative and corrective features of Nik Color Efex Pro, one of his favorite plug-ins. It is a how-to app illustrated with before-and-after examples for each filter. The app does not work like Snapseed, which is an image-editing app.

Rick says, “Plug-ins help you awaken the artist within.” With this app, you are well on your way to creating artistic and creative images, with a few clicks of your mouse.

Rick partnered with app developer Keith Kolmos on this app. Keith and Rick also collaborated on Rick’s wallpaper apps: Big Cats and Butterfly Wonders, as well as Rick Sammon’s Social Media Marketing for Photographers.
