Part Number:  WK-IP4AP-PIP2

"For a modest cost, they helped me build my PI repertoire and improve my images. In the context of paying thousands of dollars for equipment, computers, and software, IP4AP’s tutorials provide outstanding value for the money. I would recommend it to anyone who is serious about harnessing PixInsight’s vast capabilities to make beautiful space photos."  Dr. Ron Brecher​ - Astronomy Magazine

Warren Keller joins forces with PixInsight expert, Rogelio Bernal Andreo to bring you a new series of DVD tutorials focused entirely on the astro-image processing software, PixInsight.

PixInsight is the brainchild of Juan Conejero, a Spanish software developer who has led Vicent Peris and the 'PTeam' since 2004 in PI's development. If you're new to image processing, PixInsight is a very powerful and much less expensive alternative to Photoshop. New modules are being added all the time, eliminating the need for astro-specific, 3rd-party plugins as with Photoshop. Because it was specifically designed for Astrophotography, it has definite advantages over Adobe CS and we can see a time in the near future when its postprocessing abilities will surpass Photoshop in many areas.

In Part-2 of the series, we'll perform permanent, nonlinear stretches, reduce noise, develop amazing detail, and perform many other enhancements using the power of multiscale wavelets transformations.

'IP4AP's PixInsight tutorials are a must-see for anyone opening up the PI toolbox. I highly recommend this series. You will not only climb the PI learning curve, but enjoy it at the same time!'

Ken Crawford, President
Advanced Imaging Conference, Inc


'Despite using PixInsight for three years and achieving major milestones in my processing, I've found IP4AP's series to be wonderfully helpful. Warren's clear scripting combined with Rogelio's expertise truly illuminate the complex parameters of PI's powerful functions. These tutorials have already significantly improved my workflow, and I can't wait for each new release!'
