Legacy Subscription Home Page

As of April 2016, IP4AP.com moved to a monthly subscription model. Users that purchased any of our previous series will continue to have access to them through this page. Please bookmark this page for future reference. We hope that you will check out our new offerings that will allow us to provide new content on a more frequent basis. Please review the information below for more details and check out our new IP4AP.com home page. -  Warren Keller & Peter Proulx

Introducing Monthly Subscriptions 

IP4AP.com is changing in a big way, with the introduction of our low-cost monthly subscription model! This is an 'all you can eat buffet' featuring all of our existing content, and more!

To date, we've produced separate series, each taking a full-year to complete. While the vast majority of these series remain current and relevant, our new model allows us to add fresh content in real-time, keeping you up to date with the latest techniques and revisions of the covered software.

With this new and exciting change, IP4AP.com also becomes Pix-Centric. While you'll eventually see updated content on Adobe Photoshop and other image processing software, PixInsight becomes our Prime Focus.

What can you look forward to? Object-Oriented video and text-based PixInsight tutorials, User requests for specific tutorials (we might even feature your data!), Access to exclusive content featuring image data, projects, workflow crib sheets, New Instance process icon sets, tips and tricks.

Online Workshops

imageWe'll use the power of the WEB to bring you periodic informative workshops. Don't worry if you can't make it- they'll be archived for viewing at your convenience. 

PI Resources

Want access to your tutorials while away from your Internet connection? Many of our series are available for download, or as an IOS App. When we develop a sufficient amount of new content, we'll offer these for sale in offline formats as well.
