Originally posted by drewdlephone It does seem as though you can do so much with it when you change things like the developer, the time and temperature of your work environment, etc. It must be nice to have the space and time, and materials. I could probably pick up a lot of stuff and do it myself on the cheap, but the wife says the kitchen sink is off limits. "No chemicals", is what she said.

The following applies only to the United States, which is where I live..Things may differ in other countries, especially Third World countries..The following also only applies to separate film versus digital camera-to-print systems, and not to any hybrid system combining the two processes..
My finances have prevented me from re-entering black and white film photography as soon as I had hoped to..I have had over a year to do research into the relative toxicities between film and digital..I did this research so I could decide whether, or not, to build a darkroom in my home..I was concerned about the toxicity of film processes, as I had last developed film and prints in the mid-1980's..Unfortunately, I cannot quote sources as the computer that I had all of this information stored on crashed, leaving me with no recoverable info..And, I never bothered to go back to resource out all of the info as I had pretty much decided which way to go as regards to building a darkroom..
Let us compare EVERY process in the history of film from the earliest days to the present, against a complete modern camera-to-print digital system..If we take into account every aspect of manufacturing all of the equipment, materials, and chemicals needed for both systems, we find that both methodologies are pretty much equal in damage to the environment, and the toxicity dangers that the end user faces..
Looked at more closely one finds that many, if not most, of the more toxic film processes are seldom practiced any longer..When they are practiced, such as selenium toning, these more toxic chemical processes are heavily regulated..There are often stringent rules regarding the purchase, use, and disposal of the chemicals, and the waste products generated by the process..
There has been a rapid decline in color film manufacturing and usage over the past 15 years due to the growing popularity of all types of digital cameras..Modern color film processes are far more toxic, from manufacturing to end usage, than are modern black and white film processes..This also effects the equation when comparing film and digital..
Next look at the relative complexity and disposability of all the components in a complete camera-to-print digital system..Most digital components used regularly will have lifespans measuring between 5-20 years..Cameras, computers, monitors, printers, and all of the ancillary equipment just do not last as long as their film counterparts..In addition, those components that have the longer lifespans, such as high-end printers, generally require regular and expensive maintenance in order to eke out a long period of usage..In general, film equipment is simply more robust, and less complex, than its digital counterparts..Most mid-priced to upper end film equipment has a lifespan measured in decades, usually from between 3-10..This must also factor into the equation..Film equipment generally lasts a long time, most digital equipment generally ends up in a landfill in 10 years, or less..
Now consider that very few photographers are going to develop color films at home..The ones that do choose to develop color film in their homes certainly must take into account the much greater toxicity of the color process to themselves, their children, their pets, and the environment..One should not be flushing these chemicals down the drain, or into a septic system..Other methods of disposal should be chosen..
When all of these factors are taken into consideration it becomes glaringly obvious that black and white film represents far less of a threat to photographers, their families, their pets, and the environment than the general public commonly believes..Because the chemicals for developing black and white film are smelly, most people just assume that they are very toxic..Not so..
The two main hazards that the digital system poses to photographers, their families, etc. is from ink jet printers and the computers utilized in every aspect of the process..All ink jet printers expel an enormous amount of super fine ink droplets into the air as the printer head moves back and forth..Because these cannot be seen by the naked eye most photographers are unaware that these droplets are being breathed in by anyone in the vicinity of the printer..If the home is equipped with a forced hot air heating and cooling system, then these droplets are being drawn into the return air ducts, and recirculated back into the home's air supply..The inks for ink jet printing are fairly toxic, especially those chemicals used as carrying agents for the pigments or dyes..If I was going to run one of these on a regular basis I would design and implement a hood and fan system over the printer similar to the types used over cook stoves..I would use such a system to keep the air in my house as clean as possible..The other danger that the digital system poses is in the electromagnetic radiation that all of the various computers give off..This is a danger that most of us just take for granted, as computers are so ubiquitous in our everyday lives..But, it should be factored into the comparison between the two methodologies..A photographer does not need a computer for any part of the film / wet developing process..Computers are absolutely necessary to the digital process..
Both manufacturing film stocks and manufacturing all of the various components in the digital process, especially the chips and circuit boards, end up using a lot of water..Everything I have been able to learn leads me to believe that the digital manufacturing process requires enormous amounts of water, far more than the making of film stocks..Everything I have learned leads me to believe that digital components deteriorating in landfills release far more toxins into the water tables than do deteriorating film negatives, slides, or prints..This is kind of a gray area with little published..The manufacturers obviously do not want to publish how many toxins that they are creating and releasing into the environment during the various film and digital manufacturing processes..I stand ready to be corrected if someone has information regarding manufacturing that I have not read..
Overall, film comes out much better against digital than the average citizen would suspect..
Part of this is that with the exception of printing large digital prints, especially color ones, the digital process simply does not smell..Since most photographers are not printing high-quality, long-lasting color prints in their homes, they assume that digital is safer, and less harmful..Since film chemicals smell, it is automatically assumed that they must be bad..Another factor that I feel must be taken into account is the human propensity to fully embrace the new, while at the very same time making fun of and disparaging the old..The average citizen on the street today simply wants nothing to do with film, even if they cannot articulate why they feel this way..Out with the old, in with the new!!!..Just that simple..
So, developing black and white film and prints in the home poses no greater risks than does the digital system without the ink jet printer..Add into the equation the regular use of a decent ink jet printer without some form of ventilation system that removes the super fine ink droplets from the air; and, in my opinion, black and white film / print developing is safer for photographers, their families, their pets, and the environment..
Like several others have pointed out, look at the chemicals listed on the labels of ALL the household cleaning products that you have in your home..Then research those chemicals on the internet, or in your local library..Laundry products, dish detergents, and the chemicals in the bath and body products in your home are FAR more dangerous and toxic than are the chemicals needed to develop black and white film and prints..
I know this because over the past 18 months I have slowly been eliminating manufactured cleaning products from our home..Due to my skin's sensitivity I have tried to eliminate as many toxins as possible from our home..I have been making my own semi-liquid laundry soap from melted Ivory bar soap, Arm & Hammer Super Washing Soda powder, 20 Mule Team Boraxo powder, and water for the past three months..Along with vinegar for fabric softener (usually do not need this)..A batch of this soap, approximately 2 gallons, costs me about 75 cents to make..This costs me 2.35 cents per 1/2 cup of soap per full load of laundry..I seldom use the vinegar for softener and do not recall what a gallon costs..I use 1 cup per full load added to the rinse cycle..Any smell disappears during line drying in the sun, or in a tumble dryer..This is but one example of the many ways that a person can eliminate some of the toxins that you breathe, or come into daily contact with..Remember, your skin is the largest organ that you possess..It is also one of the most easily damaged organs, for all of its apparent toughness..
A good little 4.5" x 8" paperback book on this subject that I highly recommend is--The Naturally Clean Home by Karyn Siegel-Maier
The Naturally Clean Home
Good luck with your black & white film endeavors!!!..I hope that you can convince your wife to let you use the kitchen sink!!!..
