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 since then has been done on the Canon EOS-10D, 20D, 40D, and 6D, the Panasonic Lumix DMC-G3 and LX100, and the Sony A7Rii. 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. Since July 2003 I have been working more than full time on Imatest, so much of this website is out-of-date. Imatest is used by a great many companies to develop and test digital cameras, and is now working 24/7 in production lines throughout the world.	Medium format before 1984

News See News archive for earlier items.

November 2010. See my interview with Michael Reichmann of Luminous Landscape-com.

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.

September 2005. I cannot update this site as frequently as I'd like because most of my energy is going into Imatest.

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.

	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. We miss him 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 was a chemical engineering graduate student at Cambridge University (UK) and a superb photographer (sample on the left) when he started Cambridgeincolour.com, which is well worth visiting for its tutorials as well as images. 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?) Quang-Tuan Luong, nature, landscape, travel, and adventure photographer and creator of LargeFormatPhotography.info, has amassed an amazing collection of 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 15x22" inkjet print is breathtaking; comparable in quality to the finest silver-based prints. The landscape is far too grand and sweeping for smaller print sizes.
