Sharpening can be carried out in Camera RAW, however, in my view, sharpening is best left until 'more informed decisions' can be made within the main Photoshop program.
Usually one sharpens at the end of the image management process.
Camera RAW however can be set to show sharpening of the Preview Image only - this is a useful feature as it will give some indication about how the image will appear when finally sharpened.
use sharpening in 'Preview Only' mode
From The 'Preferences dialogue box, use the drop down menu to choose 'Preview Images Only'.
Camera RAW has the facility to reduce the amount of 'Noise' in the image.
Go to the 'Detail' tab in the RAW dialogue box and this will show the 'slider' to adjust for the reduction of 'Colour Noise'. The 'default' position is 25 which is generally OK.
|You will also notice 'Luminance Smoothing', this is another noise reduction facility and this option tackles 'noise' ('grain' is another term) in the black & white / greyscale component of the image. This is usually only an issue at high ISO settings. Generally speaking a small amount of 'Luminance Smoothing' is an advantage in creating a grain-free appearance - say around 4 or 5 or so.|
you require, the image may be resampled up or down in Camera RAW.
there is any distinct advantage in resampling at this stage is open to discussion
and is most likely camera / image dependent.
The next topic looks at how we may apply changes made to one 'RAW' image
to a whole set of 'RAW'images
