Working with the postprocessing pane
The postprocessing pane provides controls for fine-tuning an image after coarser changes have been made with the thumbs pane. Familiarity with these controls is essential to mastering Tintii.
- Decay thresholds the effect of saturation and lightness adjustments made in the thumbs pane according to the saturation of individual pixels. Increasing this slider will tend to eliminate colour from areas where it is not wanted. Increasing or decreasing the slider will tend to fine tune the edge around objects highlighted via the thumbs pane controls.
- Edge controls the contrast of the Decay effect. Moving the slider to the left tends to sharpen edges, while to the right tends to soften them. This is particularly useful for controlling highlighted objects with difficult edges, such as hair, feathers and foliage.
- Hardness controls how thumbs pane controls influence pixels in the image. At the hardest setting, all the way to the right, each pixel is affected only by adjustments for the thumb that most closely matches its colour. At the softest setting, all the way to the left, each pixel is affected equally by all thumbs. In between, each pixel is affected most greatly by the cluster which most closely matches its colour, and to a lesser extent by all other clusters, according to how closely they match its colour. This control is particularly useful when working with smooth gradients, where too hard a setting may produce undesirable edge artifacts.
