Possible to develop film then expose later?

I'd say clip the corners and develop the clippings until you find the exposed sheets.

Just cut all the sheets in half and develop on half and see which ones have been exposed. Then you can go and expose the other halfs of the unexposed film...

Welcome to the world of large format...

PS - in the past, I would have suggested trying Quickload film packets as you can write on the packets to record which have been exposed. But those are hard to get nowadays...

So, BetterSense, after all that, what are you going to do?

Is there any way you could use process of elimination to weed out the film that has definitely NOT been exposed?

In other words, you KNOW that the film could not be in one bag but only SOME of the film in the other bag might be exposed.

Then, once you have the pool of films that could be the ones you are looking for, divide the lot in half. Pick ones you think are the most likely candidates and test those first. If you have found all the film you are looking for, you are done. No further searching needed. If you do not find the ones you are looking for, pick your next most likely group of candidates and repeat the process until you have found them all.

Theoretically, you could still end up looking through every film holder in your bag but through process of elimination and "divide and conquer" logic you could potentially save yourself a lot of work.

Nope. All my white-side-out film holders are already placed back on the shelf together. I didn't think ANY of them were exposed...that's the trouble. The 3 shots from the graveyard just didn't turn up when I developed. I also have a hard time believing that I mistakenly failed to flip the darkslide on BOTH sides of the holder...and I remember shooting 3 shots in that graveyard.

What I'm going to do is wait. I have sent away a handful of sheets of color transparency film to Samy's. It's possible I accidentally put the missing (B&W) shots in with those, or that I shot the shots on color film afterall. I'm going to wait until those come back and see if there is any clear ones, or if I shot the shots on color film by mistake. If so, I will forget the whole thing. If not, I will develop the film in the holders one sheet at a time. Luckily, I have an empty holder I can use for whatever shooting I want to do until then.

Is it possible you might have forgotten to remove the dark slide for all three of those shots? My money is on them being in with the color batch.

So I have IR goggles and a place to dry the film in the dark. Has anyone actually tried this?

I can't afford to waste 24 sheets of film. That's several months worth of shooting.

I am with Mr. Lambrecht on thins one!

Will "IR goggles" actually work? I always thought they were one of those gimmicks sold from the back of comic books! Are the wavelengths they capture and amplify outside the range of wavelengths that will expose your film? Even if they are, do you think you will be able to see anything? What are you going to use for your IR source to backlight the film?

You can't afford to waste 24 sheets of film, but you can afford "IR goggles," and the time it would take you to go through this process, and the technical problems you will run into with drying wet film in the dark and attempting to reshoot it? How about affording masking tape and a Sharpie?

i say just shoot the film and hope the ones double exposed either look cool
probably not at all
or sucked in the first place

I have Eyeclops IR goggles and use them in the darkroom all the time. They do not fog film. I use them for DBI of sheet film, and other tricky things you sometimes need to do like find dropped items or slit film, etc. They have their own IR source.
