Preparing Powder Developer 

Thanks for the video! It's simpler than I thought!

Thank you for the insightful video. It is very helpful. Just one remark. You add 250ml to add up to 1l assuming you have 750 ml of liquid. However you have more than 750ml, because of all the powder that you added to the 750ml of water. The powder added to the initial volume of 750ml. Therefore, you need less than 250ml to obtain 1l. Maybe the difference is not that significant, but it seemed like a lot of powder especially from the second envelope.

Thanks for the really informative video! Indeed, it is just as simple as making coffee. I'm sure people will save a lot of money when using powder instead of liquid developers.

Thanks! I appreciate the clear instructions in real time 👌

Harvey Studios in Fredericton, NB still selling photo developing equipment and supplies.

Excellent video. I love the detail you put into showing the tools, techniques. Too many videos only talk about it and not show it truly hands on. So glad I came across your channel, looks like a pile of great content to consume!

cheers for the video.

Thanks for doing this video, very helpful. I am going to do it for the first time, I got the FPP D96 Owner but is for 1 gallon, it should be the same process as you did. Thanks once again very easy to follow as you showed it 👍

thank you so much for the video. after the solution is prepared, how long does it last in the bottle?

Do the "Instructions" specify distilled water? In the past, I've always used distilled.

Currently your video is not playing via RU-vid..?

Just curious what is the shelf life of microphen, or how many rolls can you normally process before its exhausted?

I've always used liquid developer (DD-x these last few years) and put up with limited shelf life, have you ever tried mixing up powder whilst keeping it in two separate parts, mixing it only when required and if so do they have a long shelf life prior to mixing together.

The specification for 1 liter of finished stock solution includes both the water and the dissolved volume of the powdered chemicals. This mixing technique does not do justice, although the resulting error in the mix is usually trivial. A better plan would be to mix the first three steps, water plus A plus B, giving a volume representing the water plus chemicals dissolved. then pour off 500 ml of that solution into the storage bottle. Then add enough water to the measuring cylinder to top it off to 500 ml, and add that to the storage bottle. (If you use hot water here, you will dissolve that residue he had left, which improves the mix a bit.) You should not use the storage bottle to measure "1 liter", because they have somewhat differing volumes and always hold somewhat more volume. (The exception would be those bottles which allow you to see the contents and are themselves graduated.) I prefer amber glass bottles, which in a 1 liter size can be had on-line for as little as $3, compared to the $10+ charged for those plastic bottles. Additionally, the plastic bottle cannot practically be cleaned of the residue and by-products which adhere to the inside, whereas glass is always easiest to clean. The worst are the accordion plastic bottles, which can never be cleaned and which also pass relatively large amounts of oxygen (through the plastic) to accelerate spoilage of your chemicals.
