I've been doing it at home for about 5 years now. I've been happy with it. The plusses: 1 Minimum space. I've usually had to use a closet as a 'darkroom': you just need enough dark space for the enlarger, yourself, and the light tight drum. This is true of all drum-oriented processes though. 2 The chemistry is almost as simple as black and white processing. There are 3 chemicals, 3 minutes each. Temperature is recommended to be at 75 degrees (give or take 3), but they have a chart for temperatures from about 68 to 80 degrees or so. 3 The Cibachrome drum is probably the least expensive on the market. It handles 5x7 and 8x10 fine. For about $10 you can buy an extra tube for it that handles 11x14 prints, too. You don't HAVE to use the Cibachrome drum though, nor do you probably have to be doing Cibachrome to use their drum. 4 Cibachrome is the most permanent color photo process there is. Other color processes produce the color dies chemically during processing. Cibachrome dies are built into the paper. The image is created by bleaching out excess dyes in the paper, leaving stable dies to make up the photographic image. The minuses: 1 Cibachrome is expensive. I think it's running about $2.50 per 8x10 processed at home to pay for chemicals and paper. 2 The glossy paper is the best but the matte surfaced Pearl paper is the cheapest. The glossy costs about TWICE as much per pack. I thought they were kidding when I found that out. 3 Cibachrome is weak on contrast control. There really isn't any. Rick.
