There are several advantages to shooting film, some concrete and others philosophical. When you shoot film, you are exposing light onto silver halide crystals covered in layers of dye in the instance of color film. The size of the average silver halide crystal is about 1 micron. Thus the total amount of “image receptors” for a piece of 35mm film will be about 100 million. That number will only jump up as we utilize medium or large format and you will near the one billion mark. This number of image receptors will manifest itself to the user as definable in detail, and especially so when enlarging negatives. Digital captures on a pixel, and a current pixel’s range in size from 3.4 to 11 microns. This translates to a full size 35mm sensor, say the one that is found in the Canon EOS-1Ds Mark III SLR Digital Camera as having about 14 million “image receptors”. To make matters more complicated for digital capture we have to factor in the Nyquist limit, which was discovered by a Swedish-American scientist of the same name. This sampling theorem proves that to avoid massive aliasing distortion and artifacts two pixels are needed to capture a single detail. Clearly, film has advantages in capturing details, especially when enlargements are made. This stands true today, but as the mega pixel count goes up, the gap will narrow. Advantages are not only found in the details, they continue onto dynamic range and exposure as well.
And this is why I still shoot film myself……… I”m one of the 4% who still shoot film.
