Omega Super Chromega C Enlarger

This was my last enlarger.  It was purchased new with Omicron 50mm and 75mm lens each on quick change boards, plus a 35mm light intensifier that concentrated the light to the coverage of a 35mm image.

It had fully adjustable colour dichroic filtration, quartz halogen light source, right angle light mixing box that insured even illumination. The diffused light source also reduced any scratch on the negatives from showing.

 The power tower had a regulated power supply and a digital timer with foot pedal controls


Durst RCP-20 Automatic colour paper processor

To be able to quickly print hundreds of prints in a go, I purchased a colour paper processor.  It worked on 20 cm wide paper aka 8” wide.  So perfect for 8x10 printing.  Just open the hatch on the left side, start the paper into the rollers and put the cover back on.  Now you can turn up the lights if you need to.  A few minutes later the print comes out the right side and falls into the wash tray. 

Simmard’s Simma Color drum and simma-roller agitator motor

I had worked a means to use this type of tank for larger prints in combo with the RCP-20.

  Using a multi-step, programmed timer I could match the processing time steps that occur in the RCP-20.  Once I had run small test prints through the RCP-20, I drained the required amount of each chemical from the RCP-20 for the drum, put the 20x24 or 11x14 size sheet into the tube, and add the chemical, let it roll for the programmed time, drain, add next chemical, roll for time,  drain etc. as each step required.  Resulting in large prints, and because of constant chemical balance the large print matched the small test prints. 

To improve results, I also covered the drum with thin foam/aluminium PSA pipe insulation, to retain the heat of the processing chemicals (usually at 38C or 100F) as it comes from the RCP-20

The drum sits on the Simma-roller sine wave automatic drum agitator.  It rolled the drum and the same time tipping it side to side to insure even development using the least amount of chemicals.

Saunders PR810 multiprint easel

Having a means to quickly process 8x10 paper, and yes the machine would do small pieces, I got this easel that would take a single sheet of 8x10 paper.  Over top you put one of number of different tops, each for a specific size print set for the paper.  For example one top would do two 5x7 prints on a single sheet, another 4 of 4x5, and 8 wallet size etc.  The cover door matches the size of the print, the paper itself moves on a table below and is indexed both ways to match the small prints.  So I could quickly print say four identical 4x5 prints onto a single sheet and get that into the processor quickly.

Bottom photo was the collection of easels I usually used.

The upper right held the paper without creating a white boarder, gripping paper by it's sides only

The left units were fixed size easels, sizes of 16x20, 8x10 and a 5x7/4x5 depending if mid bar was in.

Nikor Stainless steel film tanks

Also Simmon Omega looked the same.  There was short tanks, tall tanks. Small reel for 35 mm, larger one for 120 film.  The 120 size tank (taller) would take two 35 mm reels.  Just put film onto reel in the dark.  Put top on.  Turn on lights.  Pour chemical into filler top.  Turn tank over a few time to keep chemical moving over film.  Dump, add next stuff and so on.  Easy film development.

Home built colour printing analyser

I built this unit to make printing much easier.  It consists of a probe with a 90 degree reflector, connected to a flexible light pipe tube.  Inside the box, the mode switch on lower right had a wheel that moved three colour filters into place at the exit of the light pipe or no filter.  The light then went to a photomultiplier tube to measure the light level.

Four reference levels were set by the 10 turn pots at the top, one for each colour and exposure ref.  They were compared in level and shown on the meter, as well as the two LED lights above the meter.

Once I had a good colour balance for a given subject, I could take a reading of it and balance the meter out. On any additional prints one only to had adjust the filtering of the enlarger to give same level for each colour.

Printing hundreds of wedding photos on a evening could not have been made easier

Pixur 4x5 enlarger

This was a simple enlarger compared to the Chromega
Most important, it would take 4x5 sheet film from my view camera.  I generally used it for black and white or line copy images however I did have set of CP filters to fit the drawer and a voltage regulator for the power feed to the light bulb to keep the brightness and colour temperature fixed.
