Graduate that measures milliliters and ounces Storage container for stock solution Trays for working solution Kodak Dektol is a developer for black-and-white photographic paper that is a common choice for darkrooms. Dektol is a powder that you can find in 1-liter, 1-gallon and 5-gallon amounts. The directions for mixing the powder into a stock solution are printed on the envelope or box. After creating the stock solution, you need to further dilute the chemistry with additional water to create a working solution in which you can process your paper.

Hopefully it will be helpful to you too! As part of my day job, I maintain the darkroom facilities at Montana State University. For our film processing, that meant we switched to D, a classic powder developer, for which there is plenty of information on using. Why not save the trouble and mix the working solution to begin with?
Well, the working solution will expire quicker, whereas the stock solution is more stable to store. Also, it can be more useful to keep the more concentrated stock solution on hand for processing higher speed films, since trying to develop something like a film at a normal dilution would necessitate something like a twenty-minute developing time.
Using the stock solution shortens that time to around ten or fifteen minutes varying, of course, on the film. Using various film developers with various types of film seems to be very well documented, and it seems like one can find charts and advice all over the internet. The problem I encountered, though, was what to do about making a Dektol working solution— the working solution used for print developing.
The trick was finding information about the working solution, which proved to be more esoteric, which is what motivated me to put this page up— perhaps it will save you a bit of time! One fellow or fellow-ette indicated that he or she used Dektol mixed with water, another reported Someone also mentioned that he or she had heard that Ansel Adams supposedly used it Dan was able to confirm the forum information: most people use Dektol in a working solution that is usually 1 part stock solution to 2 or 3 parts water.
Come to think of it, maybe I should check Wikipedia for any information on Dektol working and stock solutions. Did the Mighty Ansel even use Dektol? Beats me— I think there are plenty of acolytes out there to ask, though.
That is, one unit Dektol stock mixed with two units water. Developing times for prints will be between 2 and 4 minutes, but go ahead and let the prints sit in the tray for as long as you prefer. Why not mix the working solution in the first place? Well, it has a shorter storage life, and oxides quicker. In the tray, you can expect it to be good for at least eight hours. In most cases, used conventional developer can be disposed of into the sink, since it can be treated as normal waste in most sewer systems.
Anyway, we usually recommend a 2 to 4 minute developing time for prints in Dektol. I think one of the main things is to be consistent, so that your usual print development style pairs well with your usual print exposure style. ANOTHER UPDATE, June 2nd, Alright, one more thing to mention that I think I neglected to make clear in the above: the reason one makes a Dektol stock solution and then dilutes it into a Dektol working solution later, instead of just making a big batch of working solution to begin with, is that the working solution has a useful life of around 8 hours.
I heard 8 hours from somewhere, but experience also indicates that, at least in a lab context and with the volume of three gallons of working solution we use per tray the life of the working solution is usually good enough to last us through the day and more to the twelve-hour mark… but your mileage may vary.
As it is exposed to air, the solution will gradually oxidize, and in the case of the print developer, take on more of a cola-looking appearance.

It is the classic standard Kodak paper developer that almost every photography student has learned on for decades. Dilute the stock solution , but stick to using it for paper unless you want to confuse your students with something that is not standard practice. D, likewise, is the classic standard Kodak film developer that almost every photography student has learned on for decades. The stock solution can be used straight or diluted The time-temperature charts will show numbers for both.
