Kodachrome and Fujichrome are very different beasts. Fuji films use the E-6 process (E for Ektachrome). Kodachrome uses K-14. Here's a brief description of K-14: The key to the Kodachrome's archival stability is that the color dyes (unlike Ektachrome and other E-6 Process films) are not placed in the film emulsion during manufacturing. Kodachrome is basically a black-and-white film with three light sensitive layers, each of which is "filtered" to record magenta, cyan, or yellow "light". During film processing, the correct color dyes are introduced into the respective layers to produce the full-color positive image. This is a much more complicated operation (the original K-11 Process required 28 different steps) than processing color films in which color dyes are already within each of the emulsion layers. But, the Kodachrome approach provides far greater color stability. E-6 can be processed in a half-hour, but K-14 slides are said to have a life expectancy of 200 years. Plus, nothing - let me repeat: NOTHING - compares to a KM (Kodachrome 25) image. its only a matter of time before km gets the boot like other films. with some of the new light sensors and newer/faster memory cards, plus the onboard memory improvements it won't be long before film is totally and irrevocably fini. i dont know this for a fact, but one of my best friends is a rather high end photographer who does fashion and hes plugged into the whole digital thing with nikon. hes told me a couple of times that nikon is working on something that will make film cameras totally and completely, and finally, obsolete. Pssst. It's a secret. Tell no one. Nikon's already done it. It's called the D200. With this beautiful lens: http://www.kenrockwell.com/nikon/70200vr.htm And the 28-70mm of course. -- John H ******Have a spectacular day!****** Except for the fact that it has the same damned sensor-lens problem as the D70. What problem are you having, Harry? -- John H ******Have a spectacular day!****** It doesn't have a full-frame CMOS sensor. If it did, I would have bought one last week. You really need that, huh? Personally, I don't consider it a problem. -- John H ******Have a spectacular day!****** |
