hello,

I want to experiment a bit with pushing films, but my camera doesn't allow me to change DX-codes. Once I put a film in, it reads the DX-code and there's nothing I can do. Does anyone know if I can 'hide' the DX-code someway by sticking a paper on it or so ?

Thanks in advance !

Natalie

Some cameras have the ability to deliberately "overexpose" or "underexpose". So if you want to push by one stop, just tell the camera to "underexpose" by one stop.

If you don't have this feature then, sure, you can stick a piece of paper over the shiny bits on the cartridge. The trouble is that your camera will then default to a particular speed, perhaps ASA 100, and will then expose for that film speed.

However, you can buy stick-on DX-codes. Choose the speed you want, peel it off the backing paper, and stick it on the cartridge. In the UK, these are sold by Jessops, and many others. Doubtless they are available in your country.

Place the film into your camera. Adjust your camera to manual mode.Take a reading of your subjet and modify the initial adjust according the difference between the ISO value you want and ISO value of you film. As an example, if you are using a film with ISO 200, and you want to shoot as if it was ISO 400, then reduce speed by one stop or select an aperture one stop less. It is an annoying method but you will shoot as you desire.

Thanks for helping me out !!

Yep, my camera has the ability to "underexpose" by one stop (maybe even 2, I should check that). But since I never used this feature it completely slipped out of my mind. Thanks for reminding me ! As for the other solution of manually underexpose the film : I asked the question just to avoid that method, because when you have to act quite fast. I think it's not so convenient. But I could give it a try anyway. If all of the above solutions don't work for me, I can always go and look for those stick-on DX-codes.
