3.2.1 Colour
Press the „Colour“ button in the „Parameter“ menu to activate the „Colour“
tab:
The tab contains the following options:
Saturation: define the saturation level of
the image. “0 “means no image modification
ICC profile: defines the output colour space
of the saved image: sRGB, or AdobeRGB.
Contrast: tone-mapping, stretching of
middle tones and compression of high
tones
Automatic histogram stretching: adjusts
the lightness (in DN) from zero to the
minimum and from 2
16
to the maximum
values observed in the image. The tool is
limited to 1f-stop
All settings in this tab are applied on the raw image when it is converted into RGB only
(for image preview and when saving the image as .tiff or .jpg). When saving a
panorama as a raw image, only the white balancing values are saved with the .dng file,
all other “Colour” and “Optimisation” options are not saved.
Use only a moderate amount of sharpening or noise removal. A
moderate use of sharpening and noise removal can increase the overall
image quality. Please note that once the image is saved as a tiff or jpg,
these modifications are permanent and cannot be reversed for the saved
image. We recommend to save the image as a dng (raw) file whenever
possible and to apply the optimisation only in post-production.
Noise removal: applies a noise reduction filter to the image
Sharpening: applies an unsharp mask filter to the image to create better transitions
from dark to bright pixels
Colour noise removal: applies a noise reduction filter on the high frequency parts of
the image reducing the colour noise
AdobeRGB is the larger colour space, so the colours will saturate more
quickly in sRGB. For output requiring fine detail (such as fine-art printing)
it is therefore recommendable to work in AdobeRGB.
