Tips for Doing it Yourself
- Mounting the film in your castaway camera is perhaps the trickiest part, as it needs to
be done with a great deal of care. We suggest that you use standard photographic film (say, 200 ASA) and that you only reveal something like 5cm (2 in.) sections of it at a time.
- Do bear in mind that shop-bought film is much more sensitive than our castaway film,
so try out various exposures, from one second to ten seconds in half-second
steps, and then from ten to 60 seconds in five-second steps.
- Also vary the size of the camera's aperture by placing different sized cut-out holes
underneath the lens from a pinhole to one that's 0.5cm (about 3/16 in.) in diameter.
- As you expose the film, roll up the used part and cover it with something light-proof.
This is really fiddly and requires a lot of patience. Once all the film
has been exposed, roll it back into its canister and get it developed
you'll need to warn the developer that some of your photos
might not be very good!
