What Happens If I Open The Back Of My Camera

Mike Kennedy

Dang information technology!!!! I was working on an onetime camera when I inadvertently popped open up the back. The camera contains a bulk load of Tri-X 35mm (36exp) 15 shot the previous morning along the river. I slammed the camera shut (faster than the speed of light??) but was wondering just how much I had lost.

Thank you,
Mike

Been at that place, washed that.

As film passes the gate, information technology is rolled upwards inside the camera. In nearly modern 35mm cameras, this scroll of exposed film is contained merely within the photographic camera. As a outcome, when you open up the back, you will fog the film in the gate equally well as the outer layers of the roll of exposed picture. But it is possible, depending on how long the back was open, how bright the light was, and the phase of the moon, that some of the frames at the center of the coil of exposed film were not fogged.

Yous have two choices. One is to write off that coil of moving-picture show, and perhaps use information technology to exercise loading processing spirals with the light on. The other is to continue to use the rest of the gyre, process it, and see what y'all go.

Sometimes serendipity produces interesting results.

Hi Mike. I've done that one time as well. Information technology makes you lot awful careful in the future. I almost binned the coil rather than waste the chemicals developing information technology. I'm glad I didn't throw it out though every bit it wasn't nearly as fogged as I had expected and some shots were fine. Good luck.

Don't worry. Only 3-4 shots will be ruined depending on the speed of your reaction. We all did the same affair once ;-)

Carol & Argus,

What practise you mean once? I don't know about eveyone else, only I've certainly done that multiple times. Possibly I'k simply non ever looked after by the photo gnomes. Then once more, possibly I'yard forgetful. I can't call up!!!

I had a camera 1 where the back would open up if I picked it up by the strap.

All-time excuse for replacing a camera I've ever constitute - particularly as I always tried to close the camera with the d*mned strap inside!

I've done this twice (about 20 years autonomously). The start time I had ASA 400 colour print film loaded. I don't recall what speed I had loaded the second time, but information technology was colour print film. Both times, I lost a few photos -- well-nigh 5-vii, I'd estimate, merely I'd have to check the negatives to be sure. Some were completely fogged (fully black), but others had viewable images with flaws. The rest of the exposed frames were OK, although there was some fogging in the sprocket area for additional frames. Photos on the curl later on the back-opening result were, of course, just fine.

It'due south happened to me likewise. If your photographic camera has the latch for the back on the bottom of the photographic camera (like a Pentacon Sixtl) sometimes it gets defenseless on the camera bag when you pull information technology out of the pocketbook and voila! an open camera with the film in it. Bummer.

Advance it 2 frames and bang away. The rest will be good and whatever you become with the exposed portion volition be a winfall.

I take washed it more than once over the years! Normally I loose betwixt 4-7 frames when it happens...

Sure makes ya remember, until information technology happens the next time, then it makes ya think until it happens the next time! LOL

What you should do in this circumstance is quickly close your eyes and effort to shut the back as before long as possible. In a relativistic world film tin non fog if we have our eyes closed. I am sure you have heard the argument that if no one sees an apple fall off the tree there is no reality associated with information technology falling.

Approximately speaking - opening the photographic camera back is an exposure (or the second exposure of a double in example of already exposed frames) with a f/0.five lens and shutter time of ... withal long the back was open. Probably 1/2s to one s. A layer of motion picture is I guess around sixs stops of flitration. So depending on what your EV was, the quaternary leyer of exposed flick in the camera might or might not have recieved any damage, giving you lot at least 5-6 intact frames. Now, if you opened it merely a bit and more than on the film casette side, the count of probably intact frames goes up.

I don't utilize the 35mm that much anymore ;-)

Update

Well, I simply candy my "burnt film". Gauge I failed to mention that the camera dorsum popped open while I was examining it nether my lit desk mounted magnifier. ZAP!!
Eyeballed the results and to my dismay thirteen of the first 15 frames had fried. Not really a problem. I will reshoot tomorrow morn.Alive & acquire.

Happy St.Patrick'due south Day

Like state of affairs, but I got lucky...

Finished a scroll of bulk loaded Portra and was putting my kit into my automobile. I had put the exposed ringlet in my pocket (sans plastic canisiter) and went to dig information technology out to put in my camera bag. The cassette fell out of my pocket on to the ground and the end cap poped off!

I scooped it up as quickly equally possible returnining information technology to my pocket where I quite awkwardly got the end cap back on. I though nearly ditching the unabridged roll, but said "What the heck!" $5.00 at Wal Mart showed me that the roll was in the cassette pretty tightly; 3 out of 16 frames had some serious burnout. Ii or 3 others had some edge burn. They but became 3.5x5" shots...and the rest of the curlicue was fine...

Lesson: Use a piece of masking tape to characterization AND secure the edge of the endcaps of bulk load cassttes.

Heh. I've done this, not merely in 35 mm, but with a 6x9 cm 120 camera. Oddly, with 120, the frame in the gate was about unaffected, merely the ones before and after got a good bit of fogging where they were exposed between the gate and the rolls.

I had that happen with a roll of Tri-10 at Christmas. The only fried frames were in the gate, but every other negative had a repeating blueprint of light and dark bands, which I guess was a part of the Leica takeup spool (three prongs instead of one central matter, which let light in the middle, too).
