The Clark photos:

Most of the photographs on this CD were taken by Gary or Lynn Clark. Others were contributed by fellow climbers, many of whom responded to my queries in the UseNet news group rec.climbing. All photos up until mid-2002 were taken with 35mm cameras on either Kodak or Fuji slide film, with Fuji Velvia giving the best overall results. We have gone through a lot of 35mm cameras over the years, including Pentax and Canon SLRs and Pentax, Leica, Contax, and Olympus compact cameras. In mid-2002 I converted to digital cameras (Canon), and don’t currently plan to use film again.

With very few exceptions all shots were handheld, and were taken in the regular process of doing the climb; thus they are from the perspective of the lead climber or belayer.

Producing the digital images:

I scan both slides and negatives using a Canon 2700F slide scanner, then use Adobe PhotoShop software to crop, adjust brightness levels, and retouch dust and scratches. Often I adjust color balance; e.g., shots taken on a big shady face or early in the morning will always appear blue, and shots on snow often have excessive magenta. Occasionally I apply digital filters to improve sharpness or decrease graininess. The most obvious advantages of digital photography are: (1) no film or processing cost, (2) no waiting for processing, (3) no retouching, (4) instant editing in the camera, and (5) no scanning. I’m yet to discover any disadvantages.

The final images are saved in JPEG format at “Hi” (6O) quality for the CD-ROM at two different resolutions: 1024 pixels on the longest dimension, and 675 pixels for quick perusal or viewing on a small screen. For the web site, Medium (30) quality jpeg images are used at 550 pixels on the long dimension.
