Part-1 of PixInsight Series from IP4AP.com now complete!


Hello Astro-Imaging friends,

Hope you are well and happy new year to you!
Just a quick note to let you know that Part-1 of my PixInsight series is now
complete. The final chapter will be posted to the website by the weekend.

2.5 hours of excellent information is contained in 22 chapters which have been
thirteen months in the making, and carefully produced by myself, with tremendous
help from Rogelio Bernal Andreo and as always, Peter Proulx.

I would greatly appreciate you sharing this with your imaging friends and
acquaintances. Several free samples are available for viewing. Thanks for your
support, please enjoy, and thanks for your time!

Best always, Warren Keller

PixInsight Series from IP4AP.com


Dear folks,
                  Here’s a formal announcement of the PixInsight series I’m working on. I wanted to share this news with you. Would you please be so kind as to help us pass the word? Thank you very much all! 

‘This time out, we board a new vehicle called PixInsight for which there is tremendous interest! Warren has teamed with PixInsight expert Rogelio Bernal Andreo, an APOD imager and recipient of AIC’s prestigious Pleiades Award. PixInsight is the brainchild of Juan Conejero, a Spanish software developer who has led 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. We’re confident that IP4AP’s succinct and to-the-point format will deliver the much needed ‘context and chronology’ to the existing information available on PixInsight- the what to do and when to do it. As with previous series, we are offering a Special Introductory Price on our Rolling Release. As each chapter is completed, it will be made available to you in streaming format. When the entire series is finished we will produce a DVD. Take advantage of this special, limited-time offer. The new, quality series by the world leader- IP4AP, on the hottest software in collaboration with its hottest user.

Once you are comfortable navigating in PixInsight you’ll learn how to harness its powerful, multiscale processing environment. ATrous Wavelets will enable you to treat large and small scale structures independently of one another. You’ll learn how to Reduce, Align, and Combine quality master files; and while still in the linear space: restore sharpness with Deconvolution, repair Gradients with ABE and DBE, achieve proper color balance with Color Calibration, and perform noise reduction with ACNR. Later, we’ll perform permanent, nonlinear stretches with the Histogram Transformation tool, develop amazing detail with HDRMT, and perform other enhancements such as selective Saturation and Morphological Transformation to reduce star sizes. Down the road, Rogelio will demonstrate his super-mosaic techniques.

PixInsight is available as a rolling release. Your purchase gives you access to new tutorials as they are posted. The online version is just $39.99! Please be patient with us as quality authoring and production is time consuming. PixInsight tutorials require a Flash enabled browser. Tutorials cannot be downloaded.’


Best always, Warren

Art at Last!

It has been my great hope to see astro-imaging accepted as the fine art it can be. I am pleased to share with you Starstruck http://www.bates.edu/x225901.xml

Now some wonderful personal news! Three prints were accepted for the Starstruck Exhibition in 2012: Pleiades, Leo Triplet, and Alnitak. I also became the newest artist on the roster of Exposures Int'l Gallery of Sedona, Arizona http://www.exposuresfineart.com/

Thank you all for your support and encouragement. For the latest, see www.billionsandbillions.com.

My very best, Warren

HDRT- High Dynamic Range Toning in Photoshop for Astrophotography

Hello gang, My hope is that you are not sweltering too badly through this long, hot summer. I'd like to share a new processing technique with you, which might take some of the heat off! Many of you are likely familiar with HDR (High Dynamic Range) techniques for terrestrial photography. You know- taking a minimum of three images of the same subject with different exposures, to maximize shadows, midtones, and highlights respectively, then blending them with Photoshop's Merge to HDR Pro or similar routine in other software. The results are often WOW, a unique and dynamic look, though artificial looking if overused. If used subtly however, it can be very powerful, and if used more emphatically, it can create surreal and very cool images indeed.

What if I told you that you could partially take advantage of HDR's 'pop' in astro-imaging, and with a single image? Have a look under Image/Adjustments/HDR Toning. While not a true HDR merging of disparate images, it is a very powerful processing tool. Its 'wow factor' is akin to, but more dynamic than what is obtained with Shadows/Highlights, a nonlinear stretch, used as an alternative or in conjunction with Photoshop's Curves. I have stated that using S/H exclusively is 'dangerous medicine' and doesn't yield the realistic look of Curves. The same is true of 'HDRT'. I recommend processing images with IP4AP techniques using Curves as the primary tool after DDP, then consider finishing off with S/H. For a real slam dunk however, particularly for nebulae- try HDRT!

Basic Image Processing

Try my settings, but experiment!
                        

After HDRT- Wow!


I might suggest that you blend in the HDRT as a Layer with reduced Opacity. You can also use Layers' Masks and 'Blend If' if you don't like its effect on the entire image. I think you'll find however that a reduced Opacity of 25-75%, it will do just fine. As you have to begin with a single-layer duplicate anyway, consider using a Pseudo-L or Luminance for the HDRT application. 

Be advised that at the bottom of the dialog is an expandable section called Toning Curve and Histogram. The great Ken Crawford is having much success with subtle adjustments there for his high-resolution work, so experiment here too if you have a mind to. For people like me who like powerful results quickly however, don't worry about it to start!

Until next time, this is Warren Keller for IP4AP- Image Processing for Astrophotography sending my best!
