FILM SWAP

Life is like a... film swap - you never know what you’re gonna get! These juxtaposed double exposures are often more exciting when shot by different people in difference places. You know the deal - shoot a roll and post to us, we’ll do the same and share the results. Say Hello - let’s film swap!

THE DX CODE

DX (Digital indeX) encoding is a standard, originally introduced by Kodak in March 1983, used by automatic cameras for detecting ISO ratings from 25-5000 on film cartridges.

WHY HACK

This will mostly be of interest for creative purposes if you’re using an automatic camera without manual ISO/ASA over-ride.

Example 1: You’re doing a film swap with someone using an automatic camera and want to half the exposure.

Example 2: You want to push/pull process using an automatic camera.

HOW TO

Either expose or cover the the areas on the film canister to match the matrix pattern of the desired ISO/ASA on the DX Code Chart above. You could simply scratch the paint of or cover with foil or cover with tape, nail varnish or other conductive / non-conductive material. For most purposes we disregard the lower row as only some DX enabled cameras use this to read the number of exposures and the exposure latitude.
