Norman Koren photography: images and tutorials

Welcome to my website, in which I share my passion for photography, my ideas, and even a Visitor's guide to Boulder, Colorado.

About the images: Prior to April 2003, all my images were captured on film and scanned. Most of my work is now done on the Canon EOS 10D and 20D. I process images with Picture Window Pro, a superb program that deserves to be better known. Manipulation is limited to dodging, burning, and adjusting color and contrast-- routine operations in a conventional darkroom that can be performed with far more precision digitally.

I am delighted to offer reasonably priced high quality prints up to 13x19 inches (longer for panoramic), made on the pigment-based Epson 2200 printer. The prints are extremely lightfast-- 75 to 100 years before perceptible fading under typical display conditions. Surfaces include Epson's beautiful Enhanced Matte and Premium Luster (more are available-- just ask).

July 2006. Gamutvision released! Visualize color gamuts, gamut mappings, and rendering intents. Evaluate ICC profile quality, analyze printer performance using downloaded profiles and scanned test prints, and see precisely how an image will change when printed. Gamutvision is a great tool for learning color management in depth. If you've been wondering what I've been up to, now you know.

March 2006. Norman remains busy enhancing Imatest. Read his interview with Steve Kapsinow, March 2, 2006. Steve is an editor of Graphics.com.

September 2005. I cannot update this site as frequently as I'd like because most of my energy is going into Imatest. On top of that I've accepted a three month contract (four days a week) with the Institute of Telecommunication Sciences, working in the field of Video Image Quality. Am I busy yet?

March 2005. My article on the new Canon Digital Rebel XT, written along with Alex Burack, has been published in DigitalCameraInfo.com. I've extended Imatest to measure the quality (color response, gamut, tonal response, and Dmax) of Printers.

January 2005. I posted images from my India trip, December 2004.

September 2004. Imatest, my program for measuring sharpness and image quality in digital cameras and digitized film images, has been released. You can now download a trial version and purchase the full version for a very reasonable price. It has kept me very busy for the last few months. I've used it to compare the resolution of the Canon EOS-10D and 20D. It is being used in reviews by Imaging-resource.com and Digitalcamerainfo.com, a new digital camera review site from the creators of Camcorderinfo.com. A number of European sites are planning to use it.

April 2004. I posted a few images from my trip to Monument Valley/Hunt's Mesa (a workshop with Steve Kossack) and Canyonlands. Part 2 also has some beautiful images.

November 2003. While visiting Boulder Jook Leung took some amazing 360 degree VR panoramas of me and a group of panorama enthusiasts having lunch at BJ's, enjoying downtown at sunset, and chez moi.

Plans

I'll be spending much of this year (2005) enhancing Imatest, my program for testing sharpness and image quality in digital cameras, digitized film images, and printers. I plan to take some time off for photography, which is, after all, the goal of all this effort.
Thanks to Imatest, my long-delayed book based on Making fine prints in your digital darkroom has been relegated to the back burner.

	William Corey (left) was an extraordinary photographer who worked with 8x10 and 8x20 view cameras. He specialized in the great gardens of Japan, splitting his time between Boulder, Colorado and Japan. William passed away March 31, 2008, after a long battle with liver cancer. He will be missed very much.
Steve Kossack (Yosemite winter image on the right) leads outstanding photography workshops in the American West, in places such as Yosemite, Yellowstone/Tetons, Death Valley, Grand Canyon, and Canyonlands. Workshop DVDs are available. Sean McHugh is a Chemical engineering graduate student at Cambridge University (UK) and a superb photographer (sample on the left). His images capture the spirit of Cambridge about as well as Atget captured Paris (that's saying a lot). His intuitive understanding of design equals that of the great Japanese printmakers. (Can you tell I like his work?) His site is worth visiting for its tutorials as well as its images. *G. Brad Lewis Kilauea Volcano, Hawaii. That's right! He lives on top of a volcano. His spectacular images are not to be missed.*
	Quang-Tuan Luong, nature, landscape, travel, and adventure photographer and creator of LargeFormatPhotography.info, has amassed an amazing collection of over 15,000 images on his Terragalleria.com site.

I enjoy meeting photographers. So if you are planning to pass through Boulder and you'd like to visit or go for a photographic hike, please let me know.

Lyrics by Peter Yarrow
who uses language with
elegance, grace and beauty
to convey the light
of the human spirit

Added after Peter's
September 6, 2001 concert
in honor of the victims
and the survivors
of September 11.

What has the
"War on Terror"
done to Peter's vision?

You remember when you felt each person mattered
That we all had to care or all was lost
But now you see believers turned to cynics
And you wonder was the struggle worth the cost

Then you see someone too young to know the difference
And the veil of isolation in their eyes
And inside you know you’ve got to leave them something
Or the hope for something better slowly dies

Carry on my sweet survivor   Carry on my lonely friend
Don’t give up on the dream   And don’t let it end
Carry on my sweet survivor   Tho’ you know that something’s gone
For everything that matters   Carry on Sweet survivor

Monument Valley from Hunt's Mesa, April 2005

Hunt's Mesa, overlooking Monument Valley, is an amazingly sacred place. Every rock is alive and has a story to tell if you can silence your mind and listen. After editing this image in color and Black & White I decided I preferred this version, which maintains the drama of B&W but provides a hint of color with an antique feeling that stimulates the imagination. A 13x19" print made on the Epson R2400 is breathtaking; comparable in quality to the finest silver-based prints. The landscape is far too grand and sweeping for smaller print sizes.
