Luma Range calculations

Artifacts on the repair Layer(s) when the Adjustment Layer has the Luma Range mask

In Capture One 20 (13.1.0), there was an issue where Luma Range masks would not include Heal and Clone Layers when recalculating the range. In Capture One 20 (13.1.1), this was fixed (see more details below).

A common use case

1. Create the first Empty Adjustment Layer, draw a mask and apply Luma Range to it, and make some adjustments that affect the masked area.

2. Add a Heal Layer and use the Heal Brush to edit an area where Luma Range is present and also where it is not.

In this instance, in Capture One 20 (13.1.0), a weird artifact on the healed area appeared as it was excluded from the Adjustment Layer below and the Luma Range Mask was calculated disregarding any of the repair Layers.

Workaround in Capture One 20 (13.1.1)

In Capture One 20 (13.1.1), the Luma Range Mask can be recomputed based on the Adjustment Layers below and all repair Layers (including the ones above).

Open the Luma Range dialog by right-clicking on the Adjustment Layer. This will force the recomputation of the Luma Range Mask considering all repair Layers.
