           <h2>What should I look out for when buying film?</h2>
           <p>When you see a deal too good to be true, the film is usually expired. That in itself is not a problem since film is usually still good years after the expiration date, especially when it was stored under good cooling conditions.</p>

           <h2>Where can I get my film developed?</h2>
           <p>Try to find a nice local lab to support. If there is none in your city, you can try one of the big retail chains in your country. Make sure to check that the lab supports your films development process (C41, E6, B&W).</p>

           <h2>How can I develop film myself?</h2>
           <p>Black & white film developing is not very difficult and can be done without a darkroom. Look for a film developing starter kit or find a local photographer group which might even have a darkroom.</p>

           <h2>Why isn’t film x listed here?</h2>
           <p>The films on this site should meet a few requirements: they are not a one-off production run, they are available from multiple international retailers and are (ideally) not just a simple rebranding of another film. You can find more complete lists on Wikipedia:</p>
