More testimonials

The Precision Carrier System was first introduced in 2003. Since those early beginnings, major improvements and upgrades have been made in design and function. Registration is extremely accurate allowing prints exceeding 30" x 40" to be made using any masking technique, retaining registration so precise that errors cannot be seen even on close visual inspection. Precision machining and ultra-smooth flat-black anodizing contribute to the look, feel and function of every carrier system.

I would like to thank a multitude of generous and gifted photographers for their valuable feedback and suggestions in helping me fine-tune and improve this carrier system throughout the years, including John Sexton, Bruce Barnbaum, Dennis McNutt, Dave Frieder, Gerard Sheridan and Steve Francis. These and so many other outstanding talents have helped assure the long term continuance of traditional methods and materials in the world of fine art photography. Lynn Radeka, 2005

Precision Pin-Regsitration Carrier System. Pictured here is the "complete system - 4x5 " which includes the Contrast Masking Kit.


The Precision Pin-Registration Carrier Systems, now available in two sizes (4x5 and 8x10), are uniquely designed to work accurately and efficiently with any and all masking techniques including Unsharp Masking, Highlight Masks, Contrast Reduction Masks, Dodge/Burn Masks, Inkjet Dodge Masks, spotting masks, as well as all others detailed in the Contrast Masking Kit. It's also the ideal tool for making precise multiple-exposures with separation negatives, special contrast masks, Shadow Contrast Increase Masks, Fog Masks and special effects requiring double-printing. The 8x10 system can also be used as a pin-registration contact printing system, giving the photographer a complete array of possible masking techniques for contact printing as well as enlarging.


  • Accurate - This system was designed primarily to assure repeatable accuracy, even at very high image magnifications. The pin-registration glass carrier will land in precisely the same spot each time it is slid into the holder frame, assuring perfect and repeatable registration. This is essential for some masking techniques as well as double-printing special effects and multiple-exposure separation negatives. Using a very accurate "wedge" design, a magnetic "catch" inside the holder assures that the carrier is "pulled and locked" into a solid and perfectly registered position every time. This eliminates the need for locks, levers or latches, all of which can easily affect precise registration. The Precision Carrier System has been tested on several different enlargers by making enlargements as high as 30" x 40" from a 4x5 original negative with no perceptable registration errors even at very close viewing distances. Your original negatives are never punched with this system!
  • Easy to use - The holder frame remains in the enlarger throughout the printing session. The carrier easily slips into and out of the holder frame. Negatives and masks can be easily and quickly placed in, and removed from, the carrier under safelights or even in total darkness without fumbling, speeding up printing time with masks considerably and reducing the danger of breaking the glass carrier.
  • Sturdy - The holder frame is made of black anodized hard aluminum with black Sentra spacers and is designed so that it cannot easily be damaged through standard use. The glass carrier is made with a "hinged" float glass, eliminating the possibility of dropping the float glass when replacing negatives or masks.
  • Versatile - This system allows for easier making and printing of masks. The holder frame can be used in a "front loading" position or can be rotated 90 degrees allowing side loading of the carrier. Also, the carrier can be used both to make masks and to print with masks. Upgraded Anti-Newton Ring versions come with a punched sheet of 5" x 5" duratrans diffusion material for mask making using this special glass. With most enlargers and light heads these carriers will allow you to print your entire negative area without cropping out important areas near the edge of the film. Awkward contact printing frames are no longer needed to make masks. Making masks and printing with masks has never been easier.
  • Adjustable - Should they be needed, replacement carriers and holders are available individually. The photographer can make fine-tuned adjustments which may be required when using a replacement carrier or holder.
  • Cost effective - The cost of the entire system - Precision holder frame, Precision pin-registration glass carrier and accompanying two-hole punch, costs less than half of the former Condit registration systems.
  • Universal - The Precision Holder/Carrier system will easily fit most 4x5, 5x7 or 8x10 enlarger types and light head combinations. It will also fit some bigger and smaller enlargers. The 4x5 version holder/frame unit is 7 1/2" square, and 7/16" thick. The 8x10 version holder/frame unit is 13 1/4" wide, 14" deep and 7/16" thick (depending on specified enlarger). Simply determine if this size will fit in your enlarger's negative stage with the head raised (with the negative stage "open").
