Well school has started in some areas, not in others. Either way it is highly unlikely a supply teacher gets a job on the first day and I did not, so I am at a loose end. That being the case, why not experiment?

I read this article recently and found it very interesting. I thought why not try it, so I did. I won’t go into the technical details as the original article has all that and the history of DX coding, read that post.

The article gives a link to a template which I downloaded. To alter the codes I had to delete the frame around the codes then the tables and texts become more easily editable. Plus as I wasn’t using labels the frames did not matter to me. I made my own page of a variety of different codes and also added a code for the +1 and -1 exposure rating because I could.

Next I found a test film to glue it on, meaning I just use the film to test the loading functions of cameras without wasting an actual film.

So the camera should show 400??

OK, so now for the actual film I want to try. An expired one I found in a point and shoot purchase. Recently I have acquired lots of point and shoots, so this hack will be very useful in trying out those cameras. Only….the first film I chose was a 200 and I set it to 50.

I tested it in a Canon EOS 300 before putting it in a point and shoot as they sometimes do not let you know the film speed on the display panel. Once I knew it was working I had to pick a camera, and there was the rub. Many point and shoot cameras have a limited ISO range. The first one I picked up was a Yashica Zoomate 70. As you can see from the photo below, the DX contacts were not a complete set of 6. On checking I found it only recognised films from 100 ISO. Hmm…

I had a look through the cameras I obtained and checked the contact points. The Pentax 738 had more than the Yashica and I found it accepted films starting from 25 ISO. Perfect.

So I put the film in there. Now you will have to wait for the results 🙂
