I tried to follow David Allen Harvey's advice of using one body, one lens (ha! with the lab fees saved I bought more glass too), and one film - for an entire year. I chose to go with HP5+ and Xtol (1=3) because I'd heard good things about them on this list. I bought the film in 50 roll boxes from B&H. I mixed the Xtol and stored it in plastic bottles contrary to the advice (from Mark Rabiner) that only glass bottles would store the stuff safely - I've had no problems with the plastic but others have had different experience. I use the local tap water too, which others may say is a no-no. I made these choices solely out of expediency. I read the Ansel Adams' "The Negative, and "Film Developing Cookbook": http://www.amazon.com/exec/obidos/tg/detail/-/0240802772/ qid=1047219230/sr=1-1/ref=sr_1_1/104-6095693-3815163?v=glance&s=books Both were somewhat over my head. So I continued to expose pretty much as the Leica's meter indicated, and I followed the Kodak Xtol instructions for developing the film to the letter at first. Soon I discovered that I could use water instead of stop bath; then that if I left out the hardener (Part B of the Kodak Rapid Fixer) or used Ilford's fixer, I could eliminate the Hypo Clearing Agent. When my results became consistent, I tried (again on Mark Rabiner's suggestion) using Ilford's agitation recommendations. Then on John Brownlow's recommendation I began to vary the agitation (less at the end, for greater compensation and edge effect sharpness). I stuck with my method until I could do it in my sleep. After about a year I ran out of film one day and bought some Tri-X because the store didn't carry Ilford. I adjusted the time based on the differences in the data sheets, but did everything else exactly the same. The results were horrible! A few weeks later someone complained that they didn't like the grain of HP5+, said it was mushy! I had just gotten a new scanner (4000dpi vs. 2700dpi) and so I did a comparison between the Ilford and that one roll of Tri-X. I liked the grain of the Tri-X better, but the contrast was all wrong. For a few weeks I went back and forth between them, but the Tri-X just wasn't working. Then I tried using Kodak's times and agitation schedule _to the letter_ on the Tri-X, and Voila! (Kodak no longer recommends diluting Xtol 1+3, and I've gotten to like the shorter times with 1+1). Of course now I'm down to the last four rolls of Tri-X, and no doubt the next bricks will be the new "improved" Tri-X that Kodak has come out with, so I'll have to change my processing and experiment some. Oh, one of the things I really like about Tri-X is that I can push and pull it pretty freely. Tri-X at B&H costs $2.09 per roll, and developing in Xtol 1+1 costs about $0.26 per roll. To get better pictures I need to shoot at least 500 rolls per year. There's no way I'd want to pay someone else to process all that film and give me back negatives that were hard to print and probably dusty and scratched! Simon, regarding the scanning question, looking at your pictures I would say that the thing you really need to do is learn to use the Curves function in Photoshop. I had a Nikon LS 4000, and had the same problem with the Nikon software clipping shadows and highlights, but I actually sold it because the LED light source was picking up scratches in the film that I couldn't see with a loupe. I now use a Minolta DS MultiPro (4800dpi in 35mm!) which has a more diffuse fluorescent light source. IMO Minolta's software sucks too so I use Vuescan. Set the black and white points very low (0.02 or so, check the histogram), ignore the film type setting or be prepared to experiment a lot. The scans come out very flat, but all the detail is there. Always scan in 16-bit grayscale and save to TIFF. Then you can ste the black and white points in the Levels dialog adjust the contrast in the Curves dialog of Photoshop without posterization. Do NOT use the brightness or contrast functions, you will get clipping and lose detail. One tip: when setting black and white points in Levels, hold the Option key(that's Macintosh, 'alt' on PC?) to see clipping; and when adjusting curves add a control point by Command (CNTRL) -clicking on any tone in the image. Ok, that's two tips :-) And if this lengthy tome doesn't help enough, send me a one-way ticket to Schiphol, and I'll come show you how it's done - no, I can only show you how I do it. Your mileage may vary.
