Appendix B - Technical Notes

All photos were taken with a Nikon FM camera, using a 43~86mm f3.5 zoom Nikkor lens. This is an old reliable combination I've had since 1979. It has manual focus, manual wind, manual exposure settings, and manual everything else. Film used was Kodacolor 200. Although I kept track of many details, I'm not one of those photographers who writes down exposure settings. All photos were handheld, except when I used a tripod for the moon over Glacier. (Yes, the waterfall was handheld, though I braced myself against a rock.)

The negatives were scanned onto PhotoCD by Kodak. This provides high quality, high resolution scans, with much more detail, especially in the highlights and shadows, than scanning a print. See the pictures of the teahouse at Lake Tahoe's Emerald Bay, or the pictures of Sedona's Mystic Hills, for examples. The close-ups of the teahouse and of the sign were taken from the same negatives and PhotoCD scans as the pictures of the island and garden, respectively. A conventional 4x6 print wouldn't have enough resolution to do this, no matter how well it was scanned. The picture of the blustery clouds at the Many Glaciers area of Glacier National Park had a totally washed out sky in the print made at the photo lab, but by adjusting the brightness and contrast, I was able to bring out the sky's detail from the PhotoCD scan. This would have been impossible if I'd scanned the washed-out print. PhotoCD gives me essentially as much control as I used to have when I did my own darkroom work, but it's much quicker and easier, and I don't have to smell those nasty chemicals.

Photos were converted from PhotoCD format to JPEG format using Adobe PhotoDeluxe 2.0, a slimmed-down (and much less expensive) version of their popular PhotoShop program. It allows cropping, resizing, adjustment of brightness, contrast, and color balance, as well as limited retouching to remove dust spots, and a few other things, which I didn't use much.

Web pages were designed using the One True Editor, GNU Emacs. A minimal amount of HTML coding was done, for two reasons: First, because I'm lazy. Second, to provide for compatibility with as wide a range of past, present, and future browsers as possible. You won't find much font magic, blinking text, or colors here, never mind Java script, animations, forms, etc. Except for the pictures, this document is optimized for use with the Lynx web browser.

For the best presentation of the pictures, your browser window should be wide enough to see the widest of the pictures, and you should set your display to use as many colors as possible, even it it means turning down the resolution of your display. The photos use 24-bit color. Depending on your browser width, the layout of photos and text may change somewhat. If the layout is ugly, change the width.
