To get back to my original statement, there is no "digital
look". A photograph recorded with a digital camera looks as it
ought to, as a capture of light without defects intrduced by the
capture medium.

There are however, some defects introduced by the digital capture system. First there is the pixelization of the light by the discrete photosites of the CCD or Cmos chip. Second, there is noise by the quantization of the recorded signal by a noisy analog/digital system interface. Third, there is the information lost by the Bayer interpolation algorithm applied to convert the discrete RGB photosites into color values per pixel. And lastly, there is information lost due to the fact that the photosites do not cover the entire chip, there is routing/wiring that takes up 30% or so of the chip where light is not captured but lost.
In conclusion, the final digital image contains defects also, they are just different types of defects from film.
