build my parodinal and my own fixer for developing BW film

Parodinal a homade film developer, why i made it?, Because i start to get dizzy with my behavior, like to cut film and only develop 4 or 5 frame. actually its ok, but it became expensive in chemical for developing film. i just use local developer, just 70cent and you can use it for 1 liter solution. the problem is, whether you develop 4 frame or 36 frame, the damage on developer is the same, not only because of silver that exhaust the developer, its also get oxidized by air. its make the developer turn bad after reuse 3 or 4 time.for finishing 36 frame cost me higher than the film it self. so i decide to make my own developer.

firt try to make d23 but, sorry, i cant find metol, its mean i cant make any of developer using metol, so my decision turn on rodinal, sorry i cant find it here, i must order it from outside of my country and its definetely cost me too much.

so i find a recepies, a parodinal, a developer made by mixing paracetamol, sodium hidroxide and sodium sulfite.

here is the recepies

Parodinal film developerWater 250 ml
Acetaminophen 30x 500mg tablets
Sodium Sulfite (anhydrous) 50 g
Sodium Hydroxide (anhydrous) 20 g


Mixing instructions: Add chemicals in specified sequence. LET STAND IN SEALED CONTAINER 72 HOURS BEFORE USING

Dilution: as Rodinal

Starting point development time: as Rodinal

Notes: Keep crystals from bottom of container with liquid when decanting, stir before drawing off concentrate for dilution. Use within 30 mins of dilution. Acetaminophen is sold as Paracetamol or Tylenol and is available from any pharmacy.

Please note that this formula has a maximum shelf life of 90 days.

i follow it exactly as it is. and the easies thing is

the weight of material can be measured with cake scales. its not as dificult as making d76.
you can find all the material in drug store and chemical store, all the material are easy to find, and not use for photography only. its all wide useable. and all so cheap, it cost me $1,5 for parodinal and fixer, and i still have lot of spare. its minimal quantity i can buy.

well the result, its not a fine grain, but its work well, dilute 1:50 means you can use it for develop more than 35 roll.

here is the example taken with ricoh KR5 and BW film expired 05, i have to compensate to iso 50 while the film are iso 100

a little note about parodinal,

1, It doesn't run well with acid stop bath just use a clean water for stop bath.
2. better use plain fixer not acid fixer.

here is my fixer formula ( widely use material, not only for photography, you can find it in chemical store, i bought it together with the parodinal material)
250gr sodium thiosulfate mix it with warm water 750 ml, after diluted add
50gr sodium sulfite, mix it.
than add water to make 1 liter solution.

for developer and fixer, only cost me $1.5 doesnt it soo cheap? and the best thing.. it still can make a nice picture even with expired film.
