how much can apx100 be pushed?

[palabras]

I have some rolls of this film, and I'd like to use it for my next work, in which I should use 800iso film.

Can I push this film to 800 or even 1600? Which would be the result?
Or is it better to use a 400iso film?


(I like to see a bit of grain...)


By the way: this is my first post in this forum. I hope you'll understand my bad english and to learn many things and teach some.

I find it to be a true 80ASA film. The most I ever pushed it was 400 and it turned out really contrasty (but usable) in D76, and basically nonexistent in HC110. I haven't tried with xtol, and I've run out of film.

I wouldn't push it, it looks too nice as a slow film (and some FINE grain). But if you must, push to 200 max.

I agree with the above. In general, film doesn't like to be pushed. Yes, you'll get your grain increase, but you'll lose shadow detail and gain contrast.

If you'd like grain with this film, but would like to keep its tonality and shadows, try souping it in Rodinal.

Where are you situated ? It would help if you added this info to your Forum Profile.

If you are in the States, find Diafine and use it. If you are in Europe, find Tetenal's Emofin. Instructions are included (in Emofin, at least). They will manage to get at least EI 400 out of APX 100 without too much shadow detail loss...

Don't ruin what little APX 100 is left in the world, but wasting it like this. There is some APX 400 at B&H get that and push it. What you are asking from APX100 just isn't do-able.

Ok, guys, then I'll buy some hp5 and maybe push it to 3200, using microphen stock for 17min with the usual shaking.

or have you got other suggestions? the place where I should shoot is really dark, but there are zones where the light is very high, like lamps, fires...

(joe, don't worry, i won't waste those 10 rolls of apx )


oh, thanks for the answers!!!

Cheryl Jacobs latest pic in the gallery is shot with Delta 3200 pushed to 6400, developed in T-Max. Looks good to me. (there was a url link here which no longer exists)

I have a lot of APX100. The film speed by the test is iso-125. However your batch can be different.

I also have APX400, and is iso-500 by the test. Again every batch is different and has to be tested.

APX (AGFA) combined with Rodinal, is one of the best film ever made (if not the best), and would compare to them only some ilford films. However to work at different speed (push) APX will not give you what normaly will.

The best push film is HP5 by ilford, but if you need iso-800 get ilford Delta3200 which usually is at iso-1200 at daylight, and iso-1000 at atrificial light (around 2800K).

If you go to the link below, the first picture you see (hand and book) is ilford Delta 3200 at iso-1000 (35 mm and artificial light) and developed in rodinal 1:25 (original photograph is much better).

I'd just like to support the opinion of not pushing APX100 if you like what it does at your normal speed. For higher speeds, I would prefer the Neopan 1600, Ilford HP5, or Ilford Delta 3200.
With that said, if you really want to experiment with this film, then no-one should stop you. Go discover what strange effects you might get with this film at EI 800. Who knows, you may really like it! I wouldn't expect any miracles in the area of shadow detail however, but sometimes technical details like that can be incredibly boring and stand in the way of creativity.

Delta 3200 looks very nice at EI 800, though is a little grainy. The image looks very nice, however, because the film is actually about ISO 800 - 1000.

My personal favorite for EI 800 work is Tri-X in D-76 1:1. You'll get a little more grain than at 400, but if you're LOOKING for a grainy effect, this is not the way to go.

If you want the grain, use Delta 3200.


Related to this, I have a question. What is the actual true speed of Delta 3200. I've heard reports of everywhere from 800 to 1250 (in daylight). Does anyone (or any Ilford literature) have the correct answer?

 

[MMfoto]

APX in Diafine will be passible at EI200, that's about as far as I'd go.

If you like grain and a "pushed" look try Neopan 1600 in Rodinal and shoot it in the range of 800-1600.
