Had a what-the-heck moment testing a bulk roll

I have an old bulk tin of bulk 100ft Tri-X, and since testing the two in the existing Lloyd daylight tanks seemed to come out completely opaque, I decided to swap them out and put in the Tri-X and see if I can least get the edge and see if it'll be semi-usable.

Since I only wanted to see the edge, I didn't have all my @home chemistry mixed (ie: no fixer, and just some stop concentrate). So I took a 20oz water bottle, filled most of it up, sucked up about 4ml of old HC-110 I have in an olive oil bottle with a pressure ceramic/rubber cork which has already started crystallizing at the bottom (I can re-heat it later if I really want to use it).

Cut off an end from the bulk roll and just stuck it in the bare empty tank, agitated it with water (temperature by feel), pre-wet it, then poured in the developer and kept it briskly agitated constantly for 6 minutes before throwing in the stop bath and checking.

Well I know the roll is usable (though not certain how it would exposed to the normal development conditions)... but to my surprise it seems like the bulk roll has been exposed to images, which I didn't expect seeing as it would normally be in a cartridge, not loaded en-bulk into a camera.



So... I guess I'll re-tin it and take it to school to develop a spool-worth later to see just how far the images go, though judging by the leader being blank, I suspect either 1) they spooled ahead and shot, or 2) that's the end of the roll and the whole rest of the roll has images.


The bulk roll, in original retail tin and box came from the basement of the Camera Center (in East Town, Grand Rapids, Michigan) where I used to work before it finally went out of business in late 2007.

Edit: The roll I had in the loader before tested to be Plus-X (though with just the same process as above the film is a strong even opaque grey, with charcoal black identifier on the edge), I'm guessing that's going to need a much longer development time to make it work, the opaque-ness seems too even to be fog.

Edit: #2, seeing as the only other bulk rolls I have is about 75ft of UltraTec (ISO 10, extremely high contrast ortho film), and some short ends of 2302 and 2366 (also ortho) I guess I have to bite the bullet and buy a new bulk roll of film. The professor I have for this semester doesn't mind me using old expired film as long as I test and compensate, so that's what I was hoping to do with the Tri-X.

If you hold under-exposed negative film at the right angle, it does appear to be a positive.

I'm slightly puzzled what we're looking at....is it a negative image reversed in scanning. Or is it appearing as some kind of positive image through the film not being fixed (as ic-racer is perhaps indicating).

As regards the exposures....has in the film been exposed in a bulk-film camera back ? The images seem to suggest professional or news photos of some kind of event or performance ?

inverted on the computer to show what's in the frame.



I'm only saying the bulk roll I have seems to have been exposed with images at the outside tail, suggesting the whole roll been exposed/shot, wasn't what I was expecting to find in testing it. And I had cut a previous lead off it which was blank, so I could have shot up a whole roll of 36 double exposures had I not saw that.

So I'm thinking bulk film camera back since it's about 75-footish of roll uncut.

WOW pre-exposed film! What will Kodak think of next? You do not even need a camera.

Now you know what comes out of one of those bulk film backs.
Somewhere there is a photographer who has been wondering for years what happened to those shots he/she took of that wedding/concert/???
