View Full Version : what will happen if i have asa set to 400 but shoot with 125?
Might it default to the correct asa if it's dx film and the camera (hexar rf) can read dx film or will it be otherwise screwed up?
PS: is there a shortcut to posting a new thread from the homepage or do you you have to pick the right forum first?
excuse my ignorance but when you say, "believe the film to be important" what exactly do you mean? I believe it's important in that it was all shot outside in bright sunny conditions which is why I wanted a really low speed film. Is there something else you mean?
He means "are the pictures on that roll of film important enough to take special measures with"?
You didn't say what the film is. If it's slide film, then an underexposure of roughly 1 1/3 stops (which is what you have done here) will likely be significant. Slide film usually can't tolerate too much exposure latitude, though underexposure is better than overexposure. Negative film (and I'm guessing that's what this is) may be OK, though rather grainier than if properly exposed and if it's color, the shadows will be "muddy."
If it is B&W film, and I suspect it is, you would overdevelop to compensate for th 1 and 1/3 underexposure. If you perform your own development, increase development time about 35% over normal. You may not have the desired shadow detail but you can at least increase the mid-tones and highlights.
If you plan to take it to a lab, let them know that you've underexposed and ask them to compensate in development. However, unless it's a professional lab, I doubt they will be willing or able to do so.
If you manually set the camera to ASA 400 and the film was 125, the camera will meter at 400. DX only works if the camera is set to read the DX. Some cameras don't allow you to override the DX coding, but yours must if you were able to set it at 400.
Next, yes 125 is fairly slow for bright daylight.
If you changed the ASA to manual and metered the film at 400, you have to tell the processor that you purposely pushed the film to 400, so that they can process it at 400. And that is only going to work IF.. Big IF here... the processor understands and does push processing. I wouldn't trust this to most one hour big box store places.
