How to Prevent Extreme Light Leaks on Diana Cameras


Light leaks are ok, we love it, we want it, but as they say "too much of everything is no good at all". Well, I love light leaks, but extreme light leaks can ruin your next Diana piece of art.

The film inside the Diana camera can be a little bit loose without the correct tension over the roll, specially if your film stay too long inside the camera (I had a film inside my Diana over 4 months). When you unload the film the light leaks can be extreme if you don´t protect it from light.

Sometimes you open your Diana and your film isn´t rolled tight and under a strong light or sun it can be ruined by those extreme light leaks. More often than not, it happens and It´s a pain when you are outdoors and need to unload your Diana inside a bag! If the film had the right tension inside the camera, your roll can be taken off the camera with no risks. Again, I love light leaks, but no too much of it.

To prevent it and give a good tension to the film roll, you only need glue or double sided tape, scissors, Diana camera, 120 film roll, foam and 5 minutes:

Cut a rectangular piece of foam (little bit smaller than the film roll);

Open the Diana back and glue the foam where you put the film (I used double sided tape, making it removable).

Load your film, you´ll fell a little pressure while advancing the film, that´s the foam giving some tension to it. This way you can unload your Diana under the sun, no need for changing bags or any other stuff to protect your film from light. No more extreme light leaks. Only tight film rolls.

That´s it. No complexes mods, no screws, no destruction, completely reversible. Is the same thing that new holga cameras had to prevent loose rolls and excess of light leaks.

But if you need the light leaks again, simple remove the foam, and let the loose film stuff come again.

    Oh I am definitely modding my Diana with this tip! The last roll I developed had far too many light leaks for my liking...

    I don't want to prevent any Light Leaks, I push myself the roll like the first picture to add Light Leaks :-p

    Tip: It is wise to trim the corners of the foam so the edge is rounded. I've found this prevents the likeliness that the foam will be sucked up into the roll which can cause a big mess when you want to get it developed.

    Every now and then the foam will come loose (the same with my beloved Holga). Most of the time it will get dragged across the camera and end up in your exposed roll. But no problem, just unroll your film in a dark room, get rid of the foam and roll it up again.

    Live long and prosper...

Every leak of light unveils secrets that talented photographers turn into a piece of art. Li Hui is one of those gifted artists. We talked to her about her work and her sensitive photographs that picture a wonderful vulnerability.

After all, the way we dress screams our personality; at least for most of us. And that is why, as soon as I land on a new city, one of the things I absolutely must do is find the local boutiques. Sure, I love the fancy chain boutiques as much as the next person, but there's just something else about a local clothing store. It's unique!

    So here’s what we’ve been working on: an all new

    For the last year we've been working on the next version of Lomography. We based our work on the feedback you’ve given us over the years and we wanted to share it as early as possible with you and can’t wait to hear what you think. Just one warning first: it is still in development and things can break. All the photos, comments, likes, homes and everything else were transferred as of October 16th, 2014. So anything you do on won't be reflected on and vice versa. Once we are done with testing, everything you did here will be deleted again. So this is a big playground for you to explore.
