Refining your cutout area
Erase and Restore touch-up tools can be used to refine the cutout area within the
studio before completing your cutout.
The touch-up tools are brush based and are only to be used to fine-tune
your almost complete cutout—use your Keep and Discard brush tools for
the bulk of your work!
To restore or remove portions of your cutout:
1. With your cutout areas already defined, click Preview (Output
settings tab). You can use the button to check your cutout as you progress.
2. Click the Restore Touch-up Tool or Erase Touch-up Tool
button from the left of the Studio workspace.
3. Paint the areas for restoring or erasing as you would with the brush tools.
If you've touched up part of your image between each preview, you'll be
asked if you want to save or discard changes.
Using channels
Every color photo that you use in PhotoPlus will have channels associated with
it. For the color mode RGB, the individual channels Red (R), Green (G) and Blue
(B) make up a composite RGB channel. Alternatively, channels can also be
separate, i.e. as their individual colors—Red, Green and Blue. Each channel
stores that particular color’s information which, when combined with the other
channels, brings about the full color image.
Within PhotoPlus, channels are treated as a color sub-set of the active
selected layer, whether this is a background, standard, shape or text
layer.
