+## Essential Materials
+### Basics
+The following materials are essential for developing film:
+- chemicals:
+  - developer
+  - stop bath
+  - fixer
+  - hypo wash
+- equipment:
+  - film tank
+  - film reel
+  - dark bag
+  - thermometer
+  - alkali resistant gloves
+
+### What I Use
+I have very little experience using different chemicals or brands, and there may be better options available. However, I have been using the following chemicals for the past 5 years with good results:

 - 64 oz bottle makes 5 gallons and costs $16
 - 1+9 dilution
-- Developer 50ml, water 450ml
-- Developer 100ml, water 900ml
-- you can reuse it, but I typically don't, since I think you have to modify the development time for each use

+Shelf Life:
+- Unmixed: 2-3 years
+- Mixed: 6 months to 1 year

+#### [Arista Premium Odorless Stop Bath](https://www.freestylephoto.com/6511-Arista-Premium-Odorless-Stop-Bath-16-oz.-(Makes-4-Gallons))
 
-[Arista Premium Odorless Stop Bath](https://www.freestylephoto.com/6511-Arista-Premium-Odorless-Stop-Bath-16-oz.-(Makes-4-Gallons))
+Basic Facts
 - 16 oz bottle makes 4 gallons and costs $11
 - 1+31 dilution
 - Stop bath 15ml, water 485ml
 - Stop bath 30ml, water 970ml
 - You can save this, when it turns purple it's time to replace it
 
-Shelf Life (Unmixed): An unopened bottle of concentrated stop bath can last for several years (up to 10 years) if stored properly in a cool, dark place.
-Shelf Life (Mixed): Once diluted, stop bath typically lasts for several months if kept in a sealed container and stored in a cool, dark place.
-Usage Life: A working solution of stop bath can process dozens of rolls of film or prints before it needs to be replaced. Its longevity is primarily because it’s used to neutralize the developer, which is an alkaline solution. Since the stop bath is acidic, it neutralizes the developer, and its effectiveness only diminishes as it becomes less acidic over time.

-Shelf Life (Unmixed): If stored in a tightly sealed container away from light and heat, an unopened bottle of fixer concentrate can last for 1-2 years.
-Shelf Life (Mixed): Once mixed with water, fixer solution typically lasts between 3-6 months if stored in a sealed container and kept away from extreme temperatures.
-Usage Life: For typical use, a batch of mixed fixer can process about 20-30 rolls of 35mm film or an equivalent number of prints before it becomes exhausted.

+## Steps
+### Reusing Chemicals
+If you are going to be developing several batches of film within a week, you can reuse the developer, stop bath, and fixer. As the developer wears out, you will need to increase the development times. The stop bath will turn purple when it is exhausted. 
 
+If I know that I won't be developing any additional rolls for a while, then I will discard the chemicals after use.
 
+### Roll the Film 
+
+
+### Mixing the Chemicals
+I develop in two main batches: 500ml and 1000ml depending on how many rolls of what kind I am developing. I use the following dilutions:
+
+
+| **Chemical**   | **Ratio** | **500ml**   | **1000ml** |
+|----------------|-----------|-------------|------------|
+| Developer      | 1+9       | 50 + 450    | 100 + 900  |
+| Stop Bath      | 1+31      | 15 + 485    | 32 + 968   |
+| Fixer          | 1+4       | 100 + 400   | 200 + 800  |
+| Hypo Wash      | 1+43      | 12 + 488    | 25 + 975   |
