    I use an 80's vintage Devere 8x10 enlarger and have been looking for someway to incorporate pin registration into my negative carrier for doing masking etc...any recommendations?

    thanks -andrew

    It is unlikely that you will find a pin registered negative carrier for your enlarger. Condit is no longer in business.

    The place to begin is with a film punch. If you could find one of the old Condit punches on Ebay then the next step is to have a high precision machine shop duplicate the hole spacing of the punch into pins on the negative carrier.

    I have done this with 4X5 and it is doable. Costly but doable.

    Actually the Beseler 4x5 glass carrier has enough space in it for low profile pins to be mounted to it. I made a set of 1/4" pins after getting a good film punch and using a piece of punched film as a guide drilled and tapped the carrier to mount the pins in. Mounted they hold the punched film in place and still clear the other half of the carrier.Any chance the Devere has a glass carrier and some clearance between the metal mounts for a set of pins?

    Andrew,

    In addition to my personal experience, I have encountered a photographer near me who has done the same thing that you are anticipating doing. He utilizes the same Condit punch that you describe.

    The one other consideration that I might mention is that I found it important to incorporate not only pin registration of the negative in the carrier but also the negative carrier must be indexed into the negative stage of the enlarger. This becomes very important when one does multiple mask changes in the printing of an image.

    In my enlarger modifications this amounted to "stops" on the two sides of the negative carrier with the negative stage of the enlarger acting as the rear "stop" for the negative carrier. I also incorporated a sliding/adjustable retainer that was incorporated in the left hand stop. This retainer utilizes three fine thread fasteners and firmly positions the negative carrier in the enlarger negative stage post in a repeatable manner.

    Good luck. Masking allows one to take printing into new and exciting realms.
