“The videos are outstanding. I've been using PI exclusively to process my images for some years now and accordingly have some experience and proficiency with the program. Nonetheless, found the videos to be very helpful and informative. Particularly useful are your easy to follow explanations of how the various tools and processes work. I feel certain that these tutorials will significantly shorten the learning curve for both new and experienced users.”
