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.

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.

William Corey 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.

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.

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
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.
