Equipments
for film development.
Tools
- Roll film tank
and reel.
I recommend the Nicole
type tank and reel, for example, LPL Stainless Tank. a
few measure cup.
- Few cups
For developer, Stop bath solution, fixer, or hypo clearing solution.
- Thermometer
- Darkroom Timer or Clock
- Film picker (film
retriever)
It is to pull a tip of the film which I has contained in a Patrone.
- Darkroom or dark
bag
- Sponge
A smooth sponge for a photograph.
Chemicals
- Developer
D-76,T-max,and
others.
- Stop bath solution
water, 1.5% acetic
acid solution, or Indicator Stop Bath.
- Fixer
I recommend it used
ammonium thiosulfate, Kodak Rapid Fixer and similar.
- Hypo-clearing solution
2% sodium sulfite
(Anhydrrous) solution, Kodak Hypo Clearing Agent,...

How To Develop
1. Make chemicals and control solution temperature, generally 20 degrees
C (68 degs. F).
- Following each packages of
films or chemicals
- Please do not make developer after stopbath and fixer when I use the same scalpel cups for a preparation of a medicine.
Because acid has mixed in developing solution, and there isn't developing ability.
2. Roll the reel with film in DARKROOM OR DARKBAG.
- Picking from a magazine use
with Film Picker (film retriever), then start rolling.
Development start.(under
room lamps)
3.
Pours developer from pouring gate of tank, start timer, knocks at bottom
of tank on for example a desk*, stirs continuously from 30 seconds to
a minute.
-
*Because it is removed
bubbles on surface of film.
- Stirring: Examples
of LPL tank, headstand tank, and stop a moment, and return (refer
to the right fig.).
4. Passes from 30 seconds to a minute, after that stirs two times in 5
seconds every 30 seconds.
5.
Passes development time, discharges developer from pouring gate of tank,
next pours the stop bath solution.
-
Knocks at bottom
of tank for a desk, stir continuously during 30 seconds.
6. Discharges the stop bath and pours fixer.
-
Stirring method is same
of case of developer.
7. Passes fixing time, about from 3 to 5 minutes, discharges solution,
and wash films from 30 seconds to a minute to use running water.
8. Soaks a film to hypo-clearing solution during a few minutes, then washes
above 5 minutes to use running water.
Drying
9.
Soaks a film, wash finished, to drops removing solution during 30 seconds,
hang film after that pick up it from reel, wait until drying film.
10.
To finish drying, cut a film, and files it.
