Raw File Sizes for dp Quattro
See also File Size as a Measure of Image Detail.
Shown below are the file sizes for the DP2 Merill and dp2 Quattro, the aperture series for each as shot for the Dolls comparison.
The dp2 Quattro produces slightly larger files by about 10%. Given that it has 1/3 more pixels then the DP Merrill sensor, it’s clear that there is less total information in the file on a per-pixel basis.
The variation in file sizes seen below is over the aperture range from f/2.8 to f/16 (intermediate apertures f/9, f10, f/13 are in the series also). More depth of field means more detail, which increases the file size* (unclear whether raw compression is in use or if the size difference is the embedded JPEG in the X3F).
