In "Settings" for Camera RAW in PS there's a setting for Camera Default.
What does that mean? Is that how the camera would have recorded the scene
had no adjustments at all been made? Or is that the setting for how the
scene was photographed, with whatever adjustments had been made within the
camera?
The "Camera Default" settings are contains pre-sets for Exposure, Shadows,
Brightness, Contrast, Saturation and all settings under the detail and
Calibrate tabs. These values are pre-set within PS CS RAW but can be altered
and the new values saved as the new default settings. About the only setting
that the camera directly influences is White balance but only when "As Shot" is
selected.
The camera records the scene like no film ever has or will, this is why digital
image capture is so unlike film capture, it's all linear. The RAW convertor
demosaics the RAW data and then applies curves (brightness and contrast,
saturation) in order to make the data into a form that our output devices will
present as believable rendering of the scene.
The exposure and shadows adjustments set the points in the captured data that
will be deemed as the brightest and darkest in the final image the other tools
then just apply curves to the data set between these two pre-sets.
Pre-setting the camera default is a little like standardizing on a particular
film.
