Negative Flaw: Light Leaks

Thank you to ShootFilmNotMoose:   / shootfilmnotmoose   These nifty patterns are definitely not something that you want. These indicate a light leak in the camera’s film door or, in the case of this photo, the bellows of a 4X5. Any part of a camera that holds film, be it a 35mm film door, a medium-format film back, or a sheet film carrier, can have a light leak. Accordion bellows, too, can have pinhole leaks. So let’s go through these images and see what the light leaks tell us. This first image shows a repeated pattern in the light leak and it’s along the top only. That tells us that the leak is on the bottom of the film door because the negative image is created up-side down in the camera. The pattern is interesting here and leads me to suspect that the light leak in this camera, a Canon EOS 3, is near the film winding spool. Those repeated patterns are likely caused by the stacked layers of 35mm film sprocket holes lining up slightly off-center as the camera taken the film up. A large light leak that shines light through the sprocket holes should cause a problem like that. This pattern indicates that the light leak is probably near the base of the film door by the hinge. Here’s a 4X5 negative. This negative will come up in a later video but for now take a look at the white, triangle-ish flare in the bottom right. As noted above, negatives are up-side down and reversed from real life. So we know that flare was in the top-left of the camera when the image was taken. Looking at the light in the image, for what this image is worth, we know that the sun was off to the left. So that confirms that this was definitely a light leak. We can tell from looking at this that the light leak was a bellows leak and not a film back leak. Firstly, a film back leak would have eventually fogged the whole sheet. But more importantly, the width of the flare indicates that the light source was up and away. A typical pinhole will cast a bright and narrow streak. Because this hole was up and away it cast a cone onto the negative, which is why this flare spreads out so much. This sample shows what happens with color film. The different colors of leak indicate how long the film was exposed to the leak. The brighter the streak, the longer the exposure. Also, the light purple fringe on the right side of the frame confirms that these were caused by two different leaks of different severity. The previous and subsequent frames likely had similar issues. Given the way that the leak from the previous frame splashes into this image, the leaks are likely on the flat portion of the film back rather than near the edge or hinge of the door. Here’s another color photo showing multiple light leaks. You can see the three through leaks pretty easily, but the right side of the photo also shows some smaller leaks that will become through leaks soon. So how do you rectify this? Replacing light seals is really easy. Here’s a clip from my video showing how to replace light seals with cotton yard. It should take around 15 minutes, your first time, to replace light seals on a camera. That’s definitely worth the investment to perform the repair.
