LatelyI have been developing film. Its total cost with shipping and everything was about 22 dollars. You have to understand this isnota professional way of doing things although you can get great results. This is for a small hobby not for developing hundreds of rolls, and is only in Black and White.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Tools and Materials
Here is what you need:
Chemicals: Kodak T-Max Developer and Fixer.
List of ingredients: Vinegar, rubbing alchohol, and water
Materials: Measuring cups, Timer, Storage Bottles (labels, charts, and mixing ratio on the bottle are very helpful), Wire, a Completely Darked out room, Binder clips, Pillows and blankets to put under door and block out light, Bottle opener, Small plastic tube from a pen, Roll of tape (for a weight), Film reels for developing (choose appropriate size for the mm of film you are using, and a Container large enough to hold the film reel and has a water tight lid
Tools: Plyers, and Scissors
Step 2: Developer
My developer: Was 1 part concentrate to 4 parts water. So Mix it up and store it in a bottle, I like using gatorade bottles cause they are thick and sturdy. Before you put anything in any of the bottles wash them with hot water so no sugary residue will be left on the film. I also putlabelson the bottle along with timing charts. It is a good idea to use different bottles cause in the dark you cant tell the difference in the dark.
Step 3: Stop Bath
The Stop Bath: is simply 1 part vinegar 4 parts water, and it stops the film from developing.
Step 4: Fixer
The Fixer: is probably the most complicated cause you cant mix all of it up at once. It has a shelf life of two months. It is also a weird ratio. From what I can remember it is 0.8 fixer powder to 3 parts water? All fixer is different so figure out the logistics of all the chemicals you have purchased.
Step 5: Wetting Agent
Wetting Agent: is rubbing alcohol. It prevents water marks on the film when it dries. You can buy photo-flo for cheap but I have no access to such. Detergents are good too.
Step 6: Developing Tank
The Developing Tank: is basically a plastic container with a lid. You will be agitating the fluids inside of the tank so it needs to be tight.
Agitator rod: I used a pen tube for the body. I put an eraser in the end so all of the chemicals dont get into body of it.
Step 7: Dark Room
Dark Room: Preferably a bathroom. Because it is nearly a dust-free area (the steam settles the dust) and it has a sink. Having a sink is really nice when you are washing the film, and after you can wash your tank and reels with hot water. Any room is really fine as long as it is completely dark. The test is if you cant see a white sheet of paper after five minutes you are fine. Pillows and blankets are great to put under doors and cracks that may let in sunlight.
Step 8: Now to Set Everything Up
Put everything in your dark room: and we will start loading the film. (no film was harmed solely for this instructable) First I would suggest knowing how to load the film on the reel. Now get in the dark room make sure you have everything. I would recomend having a dark thick blanket to wrap the film up in incase you forget something. This happened when i forgot scissors.
Now in the dark room: have your bottle opener prepared along with your roll of film. Pop of the bottom. take out the film on the spool, make sure you are not touching the surface of the film. Now cut off the end of the film for easier loading onto the reel. Put the end of the film into the reel and start winding it on.

Step 9: Pour in Developer
Pour in developer: Make sure to read all the directions, time it right, and dont forget to agitate. All developer is different.
Step 10: Pour Out and Add Stop Bath
Pour out the developer. Now add the stop bath, I let it soak for five minutes. Then I poured it out added tap water, agitated and poured out again.
Step 11: Now for the Fixer
Now add the fixer: I did a little research and they said leave the film in for around 7-15 minutes. I left mine in for 13 minutes it came out fine.
Step 12: Wash Wash Wash
WASH WASH WASH WASH: thats it run it under the water until you completely know that no fixer is left on the film, you can do this with the light on.
Step 13: Hang
Now hang and add the wetting agent just pour it on the film. If you are in an area without hard water you probably wont have water spots anyway.
DONE: Thanks for viewing, and happy developing!
