Photo Forum / Film Photography / Darkroom / November 2004Fuji Acros and Neopan
I've been experimenting with Fuji ACROS 100 and Neopan 400 recently as a possible alternative to my standard Delta 100 and 400 in the event that Ilford actually goes under. I'm getting very nice results with the following developer and times. For Fuji Acros: Shoot at ISO 50 1 tsp. Sodium Carbonate (washing soda) 1/2 tsp. Vit. C powder 4 ml 1% Phenidone liter of water 70 degrees Fahrenheit (21 C.) 7minutes 15 seconds, two inversions every 30 sec. For Neopan 400 ISO 200 same developer except substitute 1 tsp. Kodalk (metaborate) in place of the carbonate. 6 minutes 30 seconds Larry OK, it's my turn for a stupid question, why do you use different accelerators in the two developers?

There's really no need for different accelerators. I do it, because I like to keep my development time in the 6-8 minute range instead of a 9-12 minute range. This is because I'm easily bored, especially with film developing, and unless Car Talk or Mozart's Solemn Vespers is on the radio, I'd just as soon get it over with quicker. The carbonate is a more active accelerator than metaborate or borax, and with these particular films, it does not give me a huge increase in grain size. So, for the slower film, I still have the fine grain, but a shorter development time. If you use Kodalk (metaborate) with Acros, I'd suggest starting at 10 minutes. That'll get you very close. >OK, it's my turn for a stupid question, why do you use different >accelerators in the two developers? >OK, it's my turn for a stupid question, why do you use different >accelerators in the two developers? > > Changes developer activity. Maybe it's easier to measure. I'm sure one could use the very same developer for both films by adjusting development time. One can, indeed. The metaborate formula will process Acros very nicely--just takes 10 minutes instead of 7. >> OK, it's my turn for a stupid question, why do you use different >> accelerators in the two developers?

But i don't feel ery comfortable with your measures, can you *convert* every component in metrical to better appreciate your experimenting? ciao, Stefano SignatureEd io imparo. Sure, Stefano. Sorry, I forget that some of the readers of this newsgroup are fortunate enough to live in places like bella Italia, and don't use the American kitchen measurements of teaspoons and tablespoons. (I myself lived in la belle France for nearly ten years.) Here are metric equivalents: 5 grams Kodalk (metaborate) = 1 teaspoon 6 grams carbonate= 1 teaspoon 2 grams Vitamin C powder = 1/2 teaspoon 1 gram Phenidone= 1/2 teaspoon (dissolved in 100 ml 90% alcohol to make a 1% solution. So, you can substitute these amounts in the formula, and it should work fine. Bonne chance! >Ah, però!

Looks very nice. Blazej Did you rate the film at ISO 400 or 200? I haven't tried it using metol instead of phenidone, though I do use metol in my paper developer.

I don't care much about shadow detail;-). Blazej |
