I've used the Analyser Pro for a couple of years, and it works well for general subjects such as landscapes, group shots, etc. However, portraits require a bit of work to get skin tones and shadows where I want them. This is because the machine tends toward producing lighter shadows than I generally like. The Analyser Pro manual does point out that portraits are a special case. No doubt you can set up the AP to accomplish whatever tones you like, since the user calibrates the machine for each paper he uses, which allows going for any tones you want at the top and bottom of the scale. And you can set up different calibrations for the same paper to accommodate different subjects. Eight calibration schemes are stored, and I doubt that many of us print on eight different papers. Also, if you use variable-contrast paper and filters, at least Ilford, there's some sort of hiccup in the AP's program that makes the meter's reading for grade 3.5 filters wrong. The manual instructs you to subtract about a third or half a stop of printing time from whatever the meter tells you. This is done simply enough, though, by tapping the time button. (Why is that adjustment not built into the software?) I think the AP needs to be used very frequently, which I don't do, so that the combinations of buttons that must be tapped to invoke its various functions become more habitual and require less thumbing through the manual. I suggest you visit the RH Designs web site and read the AP manual before investing in the device. In general, if I were again shopping for an enlarging meter, I would look for something like the old Heathkit/Mitchell galvanometer device that served me for 30 years until dropping dead in the middle of a printing session. It was simple and totally intuitive to use, since all it did was show the contrast range of the negative.
