Source corrections are meant to quickly compensate for obvious technical issues of a source material.

Exposure Comp.

This setting can be used to compensate for the exposure errors of the source media.

Unlike the Exposure setting in Print tool , this is a technical correction of the original image before any Dehancer effects are applied. Conversely, Print Exposure is rather a creative setting, the results of which largely depend on the selected profile, print media, and other settings within the plugin.

Temperature Comp., Tint Comp.

These settings technically work in a similar manner but in relation to the temperature and tint of the source.

Defringe

Defringe helps to deal with the chromatic aberrations visible at the edges that may interfere with some of the Dehancer effects, such as Halation and Bloom.

💡 Temperature and Tint compensation are better suited for strong deviations of a source, while Color Head is designed mostly for creative application and more subtle adjustments.

💡 In some particular cases Defringe may lead to visible halos around the edges in combination with the Bloom or Halation effects. Lowering the Defringe amount and radius settings helps to deal with this issue.
