let take this photo as an example.Here, we will get rid of the fluorescent orange wall. We will use the color zone module to desaturate reds, but doing so would also desaturate the lighthouse railings. We will use masks to avoid that.we now add a masks to limit the effect of the module to the wall only. Using the masks combobox from the module, we add a curve shape :And here is our final image :
editing shapes :
- you can change the radius of the circle by using the mousewheel within the circle.
- you can set the border size by using the mousewheel between the circle and the border
- you can add control points by shift+clicking on an existing curve
- you can remove corners by right-clicking on them
- clicking on an existing control point will select it, allowing you to move it and making control-hooks appear that allow you to change the sharpness of the point
- right-clicking on a control hook will reset it.
- when creating a shape, you can press ctrl while adding control-points to add a sharp corner directly
- you can use the scrollwheel to change the border width of the whole shape
- the border width can also be set separately at each control point using the available anchors.
- combining masks and blendif offers a whole new world of possibilities
- when a shape is assigned to a module, a group of shapes is automatically created. You can use that group to build complex combinations of shapes
- shapes can be moved and combined within a group using boolean operators : union, intersection, difference and exclusion
- opacity can be set per-shape using ctrl+wheel
- there is no brush painting. masks are currently limited to curves
- very complex, self-intersecting curves might not render correctly
