Versalab's Parallel laser enlarger alignment tool
Good day.
Apparently, some sales people at Calumet are telling customers that Versalab no longer makes the Parallel laser enlarger alignment tool. Not True! We still make them and people still love them. Just wanted to let people know what's going on. Thank you. Laura @ versalab.com |

Hey Dave:
Is this technique documented somewhere? -Lew "David Nebenzahl" wrote in message ...

Laura @ versalab.com That's nice to know, but you should also know that anybody can do the same job (accurately aligning their enlarger) with a simple technique requiring only two ordinary mirrors. -- "I know I will go to hell, because I pardoned Richard Nixon." - Former President Gerald Ford to his golf partners, as related by the late Hunter S.

I've had the parallel for 5 years, and I haven't replaced the battery. Should I do this myself, or would it better be done at the factory? -Peter De Smidt www.desmidt.net |

Hey Dave: Is this technique documented somewhere? Yep; several places, but the only one I can find just at the moment is http://members.rpa.net/~choffman/beseler01.htm. The method is actually very simple: One mirror is cut in a narrow strip that will be held in the enlarger's negative carrier, mirror side down, sticking out in front. A small clear spot is either drilled or scratched away so you can see down through it, with a dark circle drawn around the clear spot on the mirror. The second mirror is simply laid flat on the baseboard. (Alternatively, you could put a paper reinforcing ring around the clear spot. Anything that's visible will work.) To align the enlarger, simply look down through the hole/clear spot in the top mirror at the bottom mirror. You'll see a repeated pattern of the dark circle in a "hall of mirrors" effect. When the enlarger is in alignment, the repeated reflections will merge together into one image (or close to it, anyhow). This means that the negative stage and baseboard are parallel. This method is as accurate as it is possible to align any enlarger. No fancy store-bought equipment is necessary. "David Nebenzahl" wrote in message ...

That's true. Unfortunately, even with an large enlarger (Durst G139) this mirror method is a PITA, and the Versalab is a joy to work. I aligned my enlargers with mirrors for years and bought the Versalab some time ago, now I never want to align an enlarger without it. Martin |

mar2405 from Lloyd Erlick,
Uh-oh. Have I been silly again? I've been relying on the hype around my durst enlarger (L1200). Supposedly they do not fall out of alignment. Not true? regards, --le ________________________________ Lloyd Erlick Portraits, Toronto. voice: 416-686-0326 email: net: www.heylloyd.com ________________________________ -- |

I still, however, lust for a Versalab when alignment time comes around. I don't lust at all. In my mind the the proof of a good alignment is an enlarged, distortion free, all corners sharp, projection. The proof of that is on the easel. So, I still maintain that the best method of alignment makes use of a square, a ruler, and of course, the tools needed for the adjustments. Secondary surfaces and indirect proofs are by that method factored out. What you see is what you get. Dan |
