What chemistry do we use to develop C-41?
We work with Fujifilm chemistry, which provides us a quality control service run by chemistry experts who make sure the chemistry is in perfect condition so that the reels are always dipped in quality chemistry. It is very important to have quality chemistry, as a reel cannot be re-developed, so if any mistake happens it cannot be fixed. That’s why we make sure we always have our chemistry in top condition.
How is quality control carried out?
Daily maintenance involves cleaning the rollers, filters and surface gears of the machines. We also do a thorough monthly cleaning, with emptying of liquids and tanks as well as cleaning of the machine.The quality control of the chemistry used for developing is carried out by means of control strips, which must be passed through the developing machine and then sent to Fujifilm for an exhaustive analysis. Fujifilm then sends us a report of the results and changes and/or corrections are made if necessary.
Is the developer fluid toxic, do you know what happens to it?
At Visualkorner we are aware of the impact that developing liquids have on the environment and that is why we recycle the developing liquid, which is corrosive and harmful to the environment. The liquid is deposited inside the developing machine; therefore it is necessary to empty it and pour its content into a special chemical waste container and then hand it over to a toxic waste company that will be in charge of completing the recycling process.
And why is it important to recycle it?
Chemicals used in photography, like those used in other fields, include a wide variety of harmful products such as cyanides, organic and inorganic acids, oxidising reagents, acetones, hydrocarbons, caustic alkalis, silver compounds, mercury, etc. Because of their composition, they cannot simply be disposed of down the drain as they are chemical wastes that must be treated by specialised companies.
Do you think all laboratories do the same thing, and have you ever asked yourself this question?
It is important that you become aware and that you ask your laboratory for a waste removal certificate as, sadly, these are practices that are not usually complied with in all laboratories, as they have a very high cost that many companies are not willing to assume. We all need to be aware that it is important to preserve the planet earth so that future generations can continue to live on it. If you are looking for a laboratory where they are concerned about the management of the waste generated, you have just found it.
