Mega pix & 35mm
Has anyone actually worked out the equivalent (roughly - obviously)
resolutions between good 35mm film and the megapixel count of the average digital camera? If we knew roughly what x megapixel count related to y ISO I for one wouldn't be fretting over whether to spend a couple of grand on a new toy or fixing my gable-end (that's the side of the house for you Yanks out there ;-) ). Anyone got any ideas ? Chris |

It has been done and discussed. Try a Google search.

Anyone got any ideas ? I tried counting pixels on a frame of 35mm film but my microscope got swiped by a swarthy looking man of black beard and West Country dialect, who murmured something about angels and pinheads. -- Martin Francis http://www.sixbysix.co.uk "Go not to Usenet for counsel, for it will say both no, and yes, and no, and yes...." |

I remember it being about 10 Mpxls. It came from estimating the resolution of
a good slow film, I believe. Hack --//-- |

Anyone got any ideas ? Chris When Kodak brought out their 13 Mp camera, they announced that it matches 35 mm resolution. The resolution limitation in film is the scattering of light by the silver halide particles (halation). Film has a black backing that come off in the developer. It keeps most of the light that passes through the emulsion from scattering back, but it can't stop scatering of the incoming light. |

Anyone got any ideas ? Chris Check the Google archives for the gory details (and flame wars). Here is the readers digest version: 6 MP provides roughly equivalent overall quality to 35 mm film. The digital image will not have resolution as good as 35mm film, but it will be reasonably free of graininess. 35 MP will record all of the information that the best 35mm film can record. |

The digital image will not have resolution as good as 35mm film, but it will be reasonably free of graininess. I'd say: ISO 50 or 100 professional films with best technique will _slightly_ edge out* either 6MP dSLR digital or 8MP consumer digital. If you need ISO 400 or higher, one is far better off with a 6MP dSLR. *: Not enough to make film worth the bother, IMHO. 35 MP will record all of the information that the best 35mm film can record. I'd say: 11MP 1Ds images are better than anything anyone has ever seen from 35mm. (A bit over the top, but basically the right idea: the 1Ds is a lot closer to 645 than it is to 35mm.) David J.
