- What is the equivalent resolution of a 35mm film [duplicate]
A "35mm" frame is 36x24mm in size. Look at the resolution spec for some films and lenses. Some films were rated at nearly 200 lines/mm, but some much less. There was a tradeoff between sensitivity and grain size. That added noise and lowered spacial resolution of more sensitive films. Lenses also cover a range.
There is no one answer, because film doesn't have to bother with pixels. Here are the facts so you can decide. The best comparison I've seen is ISO 100 film compared to 10MP. Film. With film, the image is continuous in all three dimensions: x, y, and z (intensity).
23 lis 2014 · The grain of a film is equivalent to the noise in a digital photograph, not to the pixels. There is a big difference between colour films, which have images made from quite large clouds of dye, and B&W films, which have images made from particles of silver that are too small to be seen under a light microscope.
A 36 mm × 24 mm frame of ISO 100- speed film was initially estimated to contain the equivalent of 20 million pixels, [6]: 99 or approximately 23,000 pixels per square mm. Many professional-quality film cameras use medium-format or large-format films.
The 'megapixel' equivalent of film is whatever the megapixels are of whatever you're scanning it with. Film is theoretically infinitely detailed - youll eventually zoom in enough that all you can see is the grain, but there is still information.
30 gru 2021 · Film resolution depends on the grain size. High ISO film stocks have low resolution, but low-speed films can have higher resolution than a Canon R3 or Sony A7III. For example, Ilford FP4 film in 35mm has 25.3 megapixels after development, while Kodak Tri-X has approximately 13.7 megapixels.
