All 16-bit per component processing gives you 256 times the bandwidth
and precision of 8-bit.
Shift or Gain any RGB and/or HSV components
precisely, without time-consuming masks.
Flexible control over how shifting or gaining is applied to an image using adjustable
maps (curves) on the Hue, Saturation and Luminance components.
Control the roll-off on the maps so all effects appears completely
natural.
Save and load presets for use with other images.
Control not only the distribution but also the quality and quantity of the
effects applied.
Built-in Color Sampler Tool allows for accurate sampling of the colors in the
image that the filter is to be applied.
A simple interface and a thorough manual make for a sensible learning curve.
Define the source colors you wish to operate on using the built
in Hue, Saturation and Luminance (HSV) curves or maps.
Sampling the colors in the area/s or an image you wish
to affect with the built in Color Sampler Tool is a simple
way of selecting these values. Adjusting and fine tuning the curves in the
maps allows you to include or exclude certain H or S or V (Luminance)
values affected.
The slope of the curves will define how the filter is transitioned.
A near vertical line on your Map will create sharply defined
boundaries between where the filter is applied and is not,
and a gently
sloped curve on the Map will make the boundaries less defined
or ‘feathered’.
Since there are three maps (Hue, Saturation and Luminance) to
work with, you will be able to 'feather' those boundaries
based on their Hue, Saturation or Luminance value differences.
Asiva's curves are so precise, that tedious masking prior
to application of the filters are often not necessary.
The Shift and Gain filter may also be applied to
your Photoshop selections.
