What others are saying
I appreciate Warren's pragmatic
approach in recognizing the value of various image processing platforms. As
the Science Imager for NASA's Chandra X-ray Observatory, I find that having
a diverse toolset is the best approach. In this series (PixInsight), you'll
find that Warren's warm, conversational style pairs well with the
comprehensive skill set offered by the all-star team of both Warren and
Rogelio Bernal Andreo. Rather than jumping into the deep end of what can be
a very overwhelming first experience with PI, Warren takes the time to
familiarize you with the lay of the land before digging into some of
'Pixi's' powerful tools. Under Warren's helpful guidance, you'll be up and
running in no time processing your own data or using the example images from
the series. This series is certain to unlock processing mysteries for new
and seasoned astrophotographers alike.
Thanks again for a great series!

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!

You can't have enough tools in
your image processing toolbox. With all of the time, effort, and money it
takes to get the raw data, we want to make sure we don't leave any pixel
unturned. PixInsight's valuable set of processing tools can unlock that
amazing image hidden within. With any powerful solution comes complexity,
and a frustrating learning curve. Warren Keller has been a long-time master
trainer in the technical art of image processing. IP4AP's PixInsight
tutorials are a must-see for anyone opening up the PI toolbox. Warren will
take you step-by-step through the treasure trove of amazing tools to help
you produce the most dramatic images possible. I highly recommend this
series. You will not only climb the PI learning curve, but enjoy it at the

Bloody awesome Tuts !I love It ! this is so valuable to have You just have to put a DVD together along the same theme of " learning the art of processing" As I look around the different forums at newbies images, I see that we all fall into the same traps. Even though we read the same books (R. Wodaski) none of It really starts to sink in until someone goes over It with you. I think that your Tutorials are the key to a quick and easy way of understanding what we are looking at when looking at the data . Also now that I think of it, being able to present a respectable image with minimal fuss ! I can see this being the difference of some newbies sticking with It or giving It up ! Also let me add that I think you have a great voice for narrating these tuts. Anyway as you can see I'm rapped ! so looking forward to more. Warren please send me your PayPal account I want to send you a little something for your time. I'm not rich so sorry It won't be much but I am grateful for your time and effort you put into these tutorials.
Cheers, Louie Atalasidis
You really have done your homework on the interface. At a minimum, I'll be making some positive posts on Cloudy Nights, but I really would like to do something more!

I am recommending your previous series to anyone who is willing to catapult their abilities and understanding of image processing. I am quite sure my experience with the PixInsight series will not be an ounce less interesting, fun, and useful.

I've been through your tutorials
a few times and thanks to them, I'm much more comfortable with PI. In short,
I think your tutorials are really, really good, and you're doing a great
service both to PI/P-Team and the imaging community. You'd be the perfect
person to demystify it at AIC next year. Hope you've been fitted for your
tux that you'll wear at next year's Nobel prize-giving! Keep up the great

I KNEW you would be the guy to step up to this challenge and help us out! I
think I'm going to take the PI plunge. I think it is the future of image
Dr. Dave Doctor
Thanks again for this great service - PixInsight is such a powerful one-stop-shop program, but it's complex as hell for us newbies without a road-map to get started… your videos provide us with that roadmap!
Having had a couple of sessions with Warren covering essential facts about sophisticated usage of Astroart and Photoshop was like leading me out of the dark basement of astrophotography into the highlighted ground floor and further up; guys and I can tell you this is a high-rise building and Warren is the perfect guide. Warren, thanks for enriching my knowledge about digital processing! You really made my day.
Dr. Dietmar Hager, Austria- APOD Imager
Great Photoshop tutorials. Warren is a gifted teacher and communicator.

Richard Harris here from LXD55.com, LXD75.com, LX200.net, and ScopeTrader.com. I’ve visited BillionsandBillions.com and reviewed some of your video tutorial work there, great job! I’m curious if you would be interested in doing some work for ScopeTrader.com in the same area. ScopeTrader.com is a highly visited Amateur Astronomy web recourse with over 500,000 hits every month. Let me know if you are interested.

I have really enjoyed the next round of tutorials so much so I have just paid for the rest. Looking forward to going through these as well. Great stuff well done.
Best wishes rgds, Chris Traher- SMAP LTD
I am very happy with the
lessons, which are brilliant and what is very important- your English
pronounciation is fantastic, easy to understand for non-native speakers.
Thanks a lot, Stefan Baumgartner
Thank you for the replacement IP4AP Super Disk, and you are welcome for me having worn it out! I don't know if you are aware of it but you show one of my images in Photoshop Foundations Intermediate Part-2, PS-14. Unfortunately, it's the image of NGC 6992 that you show as an example of "bloated, clipped, colorless, oversharpened, distracting stars often ignored by beginning imagers". And it's all true about my image. Thanks to what I've learned from the IP4AP Super Disk, I am now producing images that have been selected as Editors' Choice on Sky and Telescope.com's Photo Gallery, used by Celestron to market the C14-A XLT on Celestron.com, used by professional radio astronomers in press releases and featured on SBIG.com. And that is just about the best testimonial I can give you! Best regards and thanks again for the new disk. I'll probably wear that one out too.
Dr. Rod Pommier
Warren, I have
to say after just a little info: WOW now I know what I am doing
wrong with my astro images. A few good ones and many many bad
ones. Thank you so much for your tutorials and your quick
responses. I just started on January 8th with a 8" Celestron
telescope and a Nightscape CCD camera with this new hobby and I
have so much to learn. You have helped to guide me in the right
Thank you again, Terry Dennis
I just purchased Soup2nuts, it’s amazing how many times I go back and listen to your tutorials. Keep working hard as it enhances my imaging skill set!!
Warren's tutorials are the perfect learning and processing tool for me. I keep them right on my desk top and when I need to refresh myself I can open them and navigate to the well laid-out chapters. In just a couple of minutes I'm able to apply them and make my images really pop.Fast, easy and perfect for anyone in every-way.
Thanks Warren, Steve Carter
The reason I'm writing is to Thank You for your great Tutorials on your Web-site. I wish there were more. I'm 64 years old. I've been a Stargazer most of my life, but since my Kids are grown, now I have the time and the money to pursue this Avocation avidly and as I never could before. Now that there is even the possibility of a total non-photographer like me being successful at it, I'm up for a Go. Your Tutorials on processing images are fantastic. I'm sure they will cut thru a lot of trial and error for me.
Thanks for the Help! Lee Paul
I enjoyed viewing your astrophotos. Great job! I appreciate the time you put into the tutorials. I'm new to astrophotography and know very little about Photoshop. I have a Nexstar NS-11 and a Canon D10 camera. I'll be using your tips shortly. I'm also in the first stage of building my own observatory. I have my pier already in place.
Thanks Again, Mark
Thank you for the outstanding tutorial on Curves! You are a gifted instructor indeed, as you readily reduce complicated concepts to easily-understood concepts.
Clear skies, Dennis Persyk
Wow I LOVED your tutorials!! There is soooooooo much to learn! We're new owners of an ETX-90 (actually it's my 10 year old son's) and think we will be trying our hand at some photography.
Regards, Gary and the Huntress family
Great job, Warren. Very good introduction to digital processing.
Thank you, Paul Verhoost- Belgium
Hello, I recently found your Photoshop tutorials on Mike Weasner's site and was wondering if you had any CDs for sale. I've been trying to learn Photoshop with little success but your tutorials are very easy to understand and was hoping you might have something available.
Thanks, Gary Greaser
I really like your tutorials on your site about PS and astronomy. How do you get your histogram window constantly in view? I use the fits plug in and guess this works as levels in PS ?
Regards, Gert Jan Scheffer
I signed up the end of last week and was able to view several of the tutorials. The tips on the "Tab" key and the 'F' key were worth the price of admission. I know that study of the Tuts will help me hone my processing skills. Highly recommended as $15 is nothing compared with what we have all invested up to this point!!
I only just noticed it and your link got me in to your fantastic Photoshop Tutorials. The tutorials really are very clear to follow and immensely helpful, even though I've been using PS 7.0 for over a year now to process my astro images, there is still much in your tutorials that I never realized before about Photoshop handling methods. Thank you so much.
Best wishes, David
Also, I wanted to thank Warren for his Curves article [in AstroPhoto Insight Magazine]. Figure 5 showing how to pick points for curves suddenly lifted a veil for me and I finally get what Wodaski book is getting at. Trying to relate the zones to an image has always confused me, but now I understand!
I've really been enjoying the tutorials. Thank you both for making a ton of knowledge available for a modest price.
Regards, Robert Hertel
I thought the tutorials were very well done. I've been in the education business for over 18 years and your approach is one that works very well. I appreciated your sense of humor and the tutorials are about the right length.
Thanks, Steve Smith
Well it's new moon this weekend and it's going to be cloudy but at least this time, I don't mind at all!! I am looking forward to learning more about Photoshop!! These are absolutely great. I wish you guys great success and if I can help in any way, let me know.
Thanks so much!! Mike Savo
I just finished to review your DVD for the 2nd time (Basic and Intermediate): now I need the new one! I read the topics that will be covered and that is exactly what I need now (as if you didn't know!). However, congrats man: it is a great series of tutorials.
Thanks for your detailed and
informative email recently received. I took your advice and signed up with
AstroPhoto Insight. I must commend you on your excellent IP4AP series and
humor! I look forward to part 2 and hope that it will be up and running soon.
I just wanted to tell you how much I enjoyed your PS Basics & PS Intermediate Tutorials. Before your tutorials I felt overwhelmed when I tried to use Photoshop, but now I feel that I have a much better understanding of the software. I was wondering if you had any guesstimate on when additional PS tutorials would be available?
Thanks, Mike Canfield
Thanks again Warren: just about to dive into the intermediate series. Again, it's been an enormous help.
Dr. Bill Caspe
Warren…First, I would like to thank you for all the help you provide to budding astrophotographers. I will be purchasing your Photoshop tutorials soon. I have PS CS and I have been self learning and using Jerry Lodriguss’ PS for Astrophotographers for a year or so. I love your sample tutorials and find your approach to teaching superior to any other.
Thanks for your help…. Dave Vosgien Southington, Ct.
I just wanted to let you know how much I've enjoyed your tutorials. They rule! When I get more proficient, I'll contact you about some one on ones.
I think AP is forever evolving, like law. Gotta keep up or get left behind. I think I've made great strides over the past couple of years, and I owe it all to IP4AP.
Ted Saker- Esq.
I am so excited to use (Celestron) AstroFX (Warren's design!). I think it's a new paradigm in ease of use, and frankly, brilliant.
