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

Not shown was a home build colour and exposure analyzer that used a fiber optical cable and prism to sample the light anywhere on the projected image, sent to a photomultiplier tube. Three colour separation filters broke the measurements down into the matching ranges of the colour head filters, plus an overall exposure adjustment reading.  I designed it to match a setting for a corrected image.  So once I had the colour of the bride’s dress looking good on a test print, I could store this reference setting, and all the rest of the prints were adjusted to match.  It also had a stored grey reference for other work. 

 

I also had a Pixur 4x5 condenser lens enlarger for the large plate film from the view camera.  It did have a filter drawer for CP filters

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, programed 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/aluminum 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.

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.
