Maco Infrared Development Confusion

[lyle_gordon]

I have HC-110 and D76 available to process Maco IR Film so I went to

look up the dev times and the massive dev chart lists the time in D76

as 8 minutes while the maco site (http://www.onecachet.com/tech.htm)

lists it at 13 minutes. Which is correct.

 

I am also wondering which filter you suggest using with it?

 

Thanks

we use d76 10 min. with water stop bath.. however if you didn't expose the film with a r76 filter, it will only look like normal b&w

I dev'd a can of IR820c two days ago for 8 minutes in D76 (undiluted) at 68F (20C). I'd used variously red, 89B and 87 filters at a stop or so different for each filter, mostly to establish a set of parameters for myself. A couple of the negs are under-exposed, a couple a bit thick, but mostly they're spot on. The exposures I used were 1/60 @ f/5.6 (EV11) with a red filter, EV10 or 9 for the 89B and EV9 or 8 for the 87. This is in full sun or thin high cloud.

The "onecachet" site isn't the manufacturer's site, it is the USA distributor's site. Don't trust it. Try instead:

click on Technical Application, then

Anyone know what the heck is:

Stamm/stock

in their tables? I assume "full strength" (a.k.a. stock solution).

[bob_teichmann]

'Stamm' simply means 'stock' in English. That's just one meaning anyway.

I hope this helps =).

 

As a side note, the only reason why I am using D-76 for this film is because the developer I regularly use is a liquid made by Clayton, and I can't find a reliable developing time.

 

I'm not a firm believer in trial & error if it costs me money =). Besides... the D-76 is about $4 cheaper for me.

 

G'Day.
