Grain focus is one thing almost every person working in a darkroom at a high standard, considers a reasonably essential ingredient to making a good print.Read More Agfa Selectset 7000 Manual FebruLooking for Agfa Selectset 5. But I think that when someone is making an exhibition type of print, they will check and re-check all things, before finally hitting the enlarger timer. I have no problem with that as within the parameters of normal enlarging they do hold their focusing ability. However the units that we used, whilst very good at keeping focus constant and virtually perfect, there was almost always a very, very slight manual change required, for super critical grain focusing. Perhaps, if we had been able to get our enlargers focusing systems properly calibrated, it would have been a different story. It was not uncommon for an enlarger to be out of commission for up to 6 months awaiting a technician, terrible really! I do wish we had, had someone like yourself that we could have called upon to maintain some of the equipment to the level envisaged by the manufacturers, when they originally designed and manufacturered it. Basically it's a numbers thing and the numbers of darkroom equipment mechanics/technicians available, was terrible 15 years ago when commercial darkroom work, was more or less at it's peak. Our rule of thumb was normal proof prints and colour stats, autofocus, for anything else we used the grain focuser.ĭF Cardwell, one of the problems in this country is the dearth of skilled people to maintain equipment. I was using both of these units in an industrial application, so sharpness was pretty much a requirement of our customers. had the ability to maintain across the range this requirement. Getting to the autofocus arrangement of your enlarger I have used both the Varioscope and the Leitz equilivent.įor standard proof printing the autofocus arrangement is excelent.įor critical enlargements, where you wish to have absolute grain sharpness, neither of them from my experience. We used some grade 5 and grade 1 Ilfospeed paper as reference. My Devere enlarger can do a range from about Grade 4½ to grade ½. Using my De Vere enlarger with colour head as a reference, we concluded that 100 M = about grade 3½ and the lowest grade was something like grade ½, quite acceptable really. It was then a simple step to work out approximate grades. This then was the standard that this enlarger can do:. I dialled 100 M for maximum contrast and got a print with correct density. I was dialling in the enlarger for someone so that they would have an idea of what grade range the enlarger is capable of printing Ilford MGIV RC paper. Last week I was using a Durst colour enlarger which also has 100 maximum for C M Y. Nicole, I've used two of these enlargers, going on your description, I'm guessing that your one is about 30-35 years old.įor using the colour head, the actual filter numbers don't mean that they aren't that different to more modern filters. Have you read the article about calibrating color heads for VC-paper by Paul Butzi? It should answer a lot of questions. It would be better to use a 105mm lens with this, the 100mm Schneider lens was just a little bit short, you'd possibly run out of adjusting range with larger paper sizes.Īfter that, the Varioscope was a joy to use, I used a grain focuser anyway and didn't rely on the autofocus. just glue the ring with epoxy to the front of the lens holder for the 105mm lens. If you can get a M42/M39 adapter ring, this could be used. To do this a fried turned a adaptor ring on a lathe. I replaced the 105mm lens with a Schneider Componon-S 5.6/100. The later "Color-Magnolar-II" are said to be better. I had a set of "Color-Magnolar" lenses and these were nothing to write home about. Over the time, Agfa used different types of lenses in their enlargers. One real problem with the variscope is that it doesn't use standard lens threads. I used the Ilford under the lens filters and got excellent results. In fact, I did this with my varioscope because the color head I had was a very old model with a high-voltage bulb (read: impossible to replace) and faded filters. You can always turn all scales to zero and use external filters. Nobody forces you to use the builtin color filters.
