Step 8 - Removing the last vestiges of the
Overview of SilverFast Ai and HDR
Adjustment Tool Palette
Many of the basic colour and
tone correction tools were discussed in the SilverFast HDR
tutorial, however, I
avoided going into any detail regarding the global
"selective colour" correction tools. In this tutorial I will concentrate
upon the "global colour"
correction, you can spend some time yourself learning about "selective
To access the "Global
Colour" correction dialog simply press the
the dialog shown below appears. This tool is designed to allow the user
to alter the overall colour balance of an image.
For now I will ignore the
top row of LED's and digits. All we need look at are the sliders, the
colour wheel and the small vertical slider (green X) shown middle
right. Pull the small slider to the bottom, this means colour correction
is on finest control, big movements still mean small changes to colour.
"Global Colour Correction" dialog
Most users will
automatically go for the 3 sliders and make the corrections by pulling
one or other left/right as appropriate. However, a quicker and much more
effective way is to use the colour wheel. Grabbing the "centre
dot" and dragging it around the wheel cause the overall image
to change, but look at the sliders, all three automatically moved. I
dragged the centre dot towards yellow to reduce the overall blue cast,
but see that some red and green were added by the system.
correction using the colour wheel
There is really no single
way to use this tool. It is extremely powerful and you should make use
of all its functions. I have only just scratched the surface; maybe
even enough to make you to try it yourself. Further guidance on basic
image editing in SilverFast can be found HERE!
