Contax T3 DX reader...pushing film?

[David_Manning]

I just finished the T3 manual (again), and it doesn't seem there is a mode for manually setting ISO for pushing film.

Aside from black tape on the DX code on the film can, does anyone know a way of manually setting the ISO? setting -2EV will get me two stops, I guess. I'm wondering if there is a more elegant way. Can I get three stops? I'd like to shoot Tri-X at 3200...

I did a google search for "film dx stickers", which came up with interesting hits including the old thread above.

Annoying, but the T3 can't do what you ask. I always prefer to overexpose C-41 by half a stop or so. Best trick is exposure compensation, locked by that custom function. Good for ±2 EV only. Note that masking the DX markings will default to 100 ASA.

I heard that you can make your own DX code stickers using cutouts of aluminum and electrical tape. You can refer to the codes that are available in the DX code wikipedia page.

Modify the DX code (tape, sticker, anything), or play with the compensation.

No other ways.

Shot with a dark (ND, yellow/orange - e.g. Heliopan dark yellow 4x, etc) filter on, additionally to setting to -2EV. Should give you another 2 stops.
Or just use Delta 3200/TMax 3200 (obviously). Then, in many instances, Delta 3200 will also benefit from a filter, so you can also use a darker filter and push Tri-X.
Tip: Use a step-up filter. More filter choices and the B+W 30.5mm filters can cause vignetting.

I never tried this much myself, except when I forget to set the EV comp back to filter + b/w film after shooting slides and having to push Delta 100 in bright daylight 🙄.

Thanks for the link to the previous thread.

A small pocketknife scraped the DX coding off in about five seconds' work. Now my T3 is shooting at 3200ISO!

Very handy to know, always wondered about cameras with DX readers and no way to manually override it. Not sure if its a good or a bad thing that I know not to avoid such cameras anymore though..
