My cautionary attitude and disdain for chemical fumes do not stem from small cans, envelopes, and bottles of photo chemicals- never had the pleasure! In my first darkroom job, we mixed all of our black and white chemistry from scratch. We purchased all the components in large quantities- developing agents, accelerators, restrainers, preservatives, balanced alkaline- we cut 99.9% Glacial Acetic Acid into the stock solution and working stop baths, stocked giant sacks of sodium thiosulphate (Hypo) and made many gallons of stock and works solution at the beginning of each production week.
Each Monday, we processed several hundred sheets of 4x5 cut film form weddings, in 4-up - 4x5 hangers in
3/ 1/2 gallon tanks and made many hundreds of proofs on Tuesday. In the print darkroom, it was not unusual t produce 300+ 8x10 and mixed sized photographs for wedding albums per day. On another day we would print over 1,000 8x10 theatrical glossies. Ever mix Nelson's Gold Toner?- the smell is enough to kill a skunk! We printed all our work, in-house, up to 30x40 prints.
In my shop, we had an in-house color lab with processing facilities for C-41 and E-6. We used 2 dip and dunk processors. For prints, we ran 2 Kodak S-Printer for proofs, 4- enlargers, and 2 roller-transport print processors. The chemistry for theses machines came in large cubi-trainers. Between the developer and the bleach/fix, there were enough carcinogens to grow tumors on a tombstone- let alone in a human being! The final stabilizer was made with formaldhde- the processor room smelled like the prep room of a funeral home! We were no allowed to drain the run-off from our machines into the sewer system- we reclaimed the silver and sent the waste to a special disposal company. We mixed 25 gallons in each of our replenishment tanks.
I did enjoy custom color and black and white printing. As for color film processing, it is a very standardized process with little room for creativity. If your C-41 process goes out of control- there is hell to pay in printing.
E-6 can be the push and pull processed for certain controlled effects. You can push it a stop or two with a sacrifice in gran structure and color accuracy. A 1-stop routine push will deliver cleaner white on some Ektachrome types. 1 stop overexposure and a pull process will reduce contrast- great for preserving shadow detail in reproducing artwork like paintings on transparency films.
Now y'all know why I don't miss the darkroom. Give me a computer, my big Epson printer, and a load of pigments and I am a happy fellow!

In the 1980s, as a small part of my 70-hour/week AV production job, I processed thousands of rolls of slides in an E6 sink line over about 8 years. Then, for the same company, I held various jobs in our school portrait lab.
We had 33 custom built optical printers, six Kodak S-printers, two custom built printers for cut negs, a 10” x10” enlarger, five APAC contact printers, two Hills cine processors for 100’ rolls of C41, a Refrema dip&dunk for sheet film, 40 home-built printers for small black-and-white and color products, four 32’/ minute x 3-10” strand Pako paper processors...
We mixed C41 and RA4 (EP2 before it) in 1100 gallon drums. We bought tractor trailer loads of 40” by 5600’ master rolls of Kodak portrait papers, and slit them down to 11”, 10”, 8”, 5”, and several smaller widths (cut to 250’ or 500’ lengths). We bought 135, 120/220, 35mm long roll, 46mm long roll, and 70mm long roll Kodak portrait films in half-truck load lots. So we had lots of volume!
Shortly after we shut down film processing operations in 2007, two long-time (25 and 35 years of service) employees died of the same cancer.
I replaced 12 dedicated low volume specialty large format optical printers —and one color technician — with a single Epson 9600 44” wide printer, in 2003.
Eventually we sent the volume from four optical labs through one digital lab, and closed the other three.
No, I don’t miss darkrooms! Digital bits beat chemical atoms 20 years ago. I was glad to get away from the stench of chemicals.
