Bluefire Police film with Developer

The negs look underexposed. The film is probably around 25 ISO in practice.

On a normal density neg you'll find the dust/spots are much less of a problem.
 
I would imagine it is very similar or might even be Agfa Copex which is a document type film which needs to be shot at less than 20EI and also needs low contrast developer for pictorial results.
Every so often a company packages these types of film (AKA Lippmann emulsions) and LC developers, I think the Blufire one is a Copex type with a developer designed to get maximum speed from the emulsion while still give printable contrast.
I tested one called Gigabit (basically Agfa Copex and Spur developer)

You can buy Copex and develop in dilute Rodinal all these films really should be shot at EI 6–25 for pictorial results.
The film looks a little different from conventional emulsions, even at EI 20 they look as if they need a little more shadow detail, I'm guessing they should be shot at lower EI

They seem to print/scan well though and are useful for certain types of shot.

Well the spent developer was likely much of the problem. I ran my first roll at ISO 80 as per the data sheet, my usual practice. I shot a lot of ATP a few years back, never really ended up getting along with that because it was so contrasty despite lots of adjustments in exposure & development. This Bluefire has been around a long time, thought I'd give it a go. I'll likely shoot this next roll at 80 and 40 side by side to see what I get, but I don;t see myself continuing with it for long. :rolleyes:

I believe it is Agfa Copex as well. Edge printing is '05 71' and 'PAN'

These do seem designed for scanning with densities like that. I don't scan film so not a good fit for me most likely. I do enjoy playing tho.
 
Yes they scan well, but surprisingly they print OK on grade 2 paper also. The emulsion is pretty high in contrast (even with special developers) at suggested speed and low in latitude–pretty much a given for a thinly coated monodisperse emulsion.
The negs I posted were at the suggested ISO40 and dev times, halving the EI to around 20 really helped.
 
hi, when i placed the order for this bluefire police, there was reference to Adox Canada.

http://www.adox.net/Products.htm

Maybe Adox CMS ? according to this website:
http://www.adox.de/english/ADOX_Films/ADOX_Films/ADOX_CMS_Films.html

if used with Adotech, iso goes up to 80, film base is also transparent.

however, according to david foy who is involved in Bluefire, i quote this:
""Bluefire Police" is Tura Pan Line, a panchromatic EI 100 microfilm, packaged in 24-exposure 35mm cassettes. Tura does not sell it in retail quantities."

another link,

"Quote from: David Foy


The film is Agfa microfilm, spooled for me by Tura when they were still in business, and edge-marked by them as "Pan Line." The next batch will be spooled here and edge-marked "Bluefire Police."
It is well suited to pictorial photography when paired with a suitable developer.
It is not sold as Adox, but as Bluefire Police. You are correct that it is bad business to confuse customers."

Frugal Photographer hasn't had developer for a while now, so I got 3 rolls and will develop in HC-110G. Well, really 1:125, I have researched a time, temp and agitation for this developer and will give it a try. I'll post as soon as have results.
 
my reference wouldn't be useful to you as
I stand developed it in tropical temperature
of 30c :)


40 Mins Rodinal Stand with mid-point agitation
at 30C
M6ttl with 50 Cron

attaching 2 images, scanned and scanned + adjustment.

I shot my first roll of Bluefire Police. I used 40 on half and 20 on the second half of the roll. My development was with HC-110 1:125 for 25 minutes, 30 seconds initial agitation, and then ONE inversion every five minutes (so four during the remaining minutes after initial agitation) 68 degrees. I got most of this from Donald Qualls on the net, but I modified a little. The negatives on the 20 EI look very good and I will post after I scan tomorrow. Just from looking at them I would say I will use 10-12 EI next roll and reduce the time to 20 minutes (and I may modify my agitation too, but I'll have to think on that for a while), but scanning is a different ball game with this clear base so we will see.

EDIT: Here are a couple at 20 EI:

As you can see so far that outdoor shots are more contrasty.
 
nice photos. especially the first one. i am surprised by the 3rd pic as it looks like a picture with an old emulsion. is it grainless as well in hc110 ?
