Q: 1. How many rolls can it develop in total?

A: The amount of rolls you can develop would depend on the film format and the size of the tank being used.

Q: 2. Is it safe to purchase Dektol again? Or is there still something wrong with it?

A: According to Kodak, there is no issue with using the currently-available Dektol developer. In an official statement from Kodak, they state that "Dektol batches with date codes of August 2019 or lager will exhibit a dark brown solution when mixed. However, image quality is unaffected - the color is due to an impurity which is no photo-active. Our manufacturing as well as an outside lab have tested the dark colored Dektol batches: Sensitometry Dmax, Dmin, paper speed, and image tone match the Dektol standard. We are working on the source of the impurity so we can get the appearance back to normal." Other than the color of the solution, there is no difference to the solution's performance.

Q: 3. Can this be used to develop Ilford HP5 rolls?

Q: 4. Do you have to mix the whole gallon at one time? Should it all be mixed at one time? How long does the developer last mixed up in a gallon jug? When you use it for 1 print developing session, do you throw out the developer that you just used?

A: Kodak recommends that you mix the entire package due to the fact that the different dry chemicals will separate and stratify in the package due to shipping. Once the stock solution is mixed with water it will keep up to 6 months in a full tightly sealed container. You can keep multiple smaller containers of the stock solution if you desire, again they should be full and tightly capped.Regarding a printing session, Kodak states a capacity of 120 8x10 prints per gallon of 1:2 dilution developer. Most people never attempt to use it to full capacity since the developer is cheap and it can be difficult to detect when the developer is becoming exhausted. You may mistake exhausted developer for insufficient exposure or contrast. If your a hobbyist then use it for something less and replace. I personally use it to 50 to 75 percent of capacity and never more that two printing session due to concern of extended exposure to the air / oxidation.

Q: 9. Why is it taking Kodak so long to fix this? Any end in sight?

A: Kodak still has not give us a delivery date on Professional DEKTOL Paper Developer (To Make 1 gal, 2019 Version).

Q: 10. To mix D-76 you put all the contents of the package in 1 gallon of water to make the stock solution, correct? Then when it comes time to develop a roll of film, do you dilute the stock solution? Do you reuse this developer after you develop 1 roll of film or do you discard? Thank you!

A: Hi, Arlen:You can either dilute the stock dilution 1+1 with water or use it straight. My preference for roll film is to use it straight, although I know that some photographers use it diluted. I dilute this developer 1+1 when I develop 4x5 film.Remember that D-76 reduces the film speed by almost 1 stop. For instance, when I shoot Kodak T-max 400, I shoot at 320. For 35 mm film, my developer of choice is Kodak XTol because in my experience it doesnt reduce the speed film, so I can shoot at 400 ASA. These are my personal preferences, and they work for me. Other photographers may think otherwise. May you have any other questions, dont hesitate to ask.
