I have a comparable RH meter (the Zone Master, I believe, it's hibernating so long now in my drawer I am not sure of his name anymore..). Although the meter is not that hard to work with, the calibration is quite tedious, and obviously has to be done on each different paper (and I used a lot different brands, less so now, so perhaps I should re-evaluate). And it takes some experience to evaluate the negative on the base board and judge were the place the sensor for the important parts . Plus in my set up (Condensor head with filter drawer above the negative) it means constantly moving filters out and in. In the end it worked better for me to have a good contact sheet and use test strips. So if I have a exposed and contacted roll of 120 film I choose the interesting ones, make a teststrip of the first (I usually know out of experience at what grade and roughly what time) I use a StopClock and a device to make a test strip of the same area at ¼ stop intervals (described in Ralph Lambrecht his book). If you choose the area carefully this strip can tells you if you are in the ballpark for the exposure time and contrast. If the first print comes out right I use that one in combination with the contact sheet to print the other images. I guess my "success rate" with this system is about 80-90%. Mind you, these smallish (13*18 cm) RC test prints are not definitive prints, but a pretty good start up to judge the content and further printing on larger FB material.

However the discussion seems to have now expanded to enlarging meters in general, and I believe in giving credit where credit is due. I use an enlarging meter from RHdesigns. details are here: http://www.rhdesigns.co.uk/darkroom/html/analyser_pro.html It is in simple terms vodoo. for a given negative I can measure the contrast range, measure particular areas and decide using the scale on the meter, where exactly I wnat to place them. The key to all of this is the user interface. Designed by a photographer and with a lot of thought put into it. this is a peice of technology which just feels like a natural extension of my photographic thinking. When I have had to print without it, as happened when I drowned my first one with fix, I now feel handicapped in the darkroom. It is an expensive piece of kit, but as they say, time is money, and the ability to grab an hour and a half in the darkroom and emerge with a well balanced, well exposed set of 36 prints from a roll of 35mm film, with only 36 sheets of paper used is not to be underestimated. This is particularly true given the level of incompetence displayed by a typical set of my negatives. I'm not saying leave it to the meter, that's the one hour photo solution. However this meter presents me with a very good set of information about any given negative and allows me to make intelligent choices about the best way to overcome any given negatives deficiencies.I'm still in charge, I just have more information on which to base my printing decisions. Despite appearances, I have no commercial connection with RH design.

This allows me to subsequently compensate for line and light source variations over time when I reprint and/or change magnifications. Because I use a cold light whose output rises with heat/time, I never start printing until the head has been plugged in for an hour or so, and when I measure the easel light, I turn the head on for 30-45 sec to allow it to come to full output. I VC split print nearly everything. That is, I turn the head on full for soft light and do any exposing, dodging, and burning with it. I then repeat with the magenta output. I find this gives me far great precision and control of local contrast without resorting to enlarging meters, which I never found useful for the most part. -- ---------------------------------------------------------------------------- Tim Daneliuk tundra@xxxxxxxxxxxxxx<mailto:tundra@xxxxxxxxxxxxxx> PGP Key: http://www.tundraware.com/PGP/ ============================================================================================================= To unsubscribe from this list, go to www.freelists.org<//www.freelists.org> and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
