Why does copying a Capture One product correction create duplicate layers or leave the old correction unchanged?

Identify the name collision before judging the result

A merchant may copy a correction named Bottle Reflection from one product photograph to another. The destination already contains a layer with that name, but its mask was carefully refined around a different bottle shape.

Capture One uses matching layer names to identify this conflict. The matching name does not establish that both layers cover identical product regions or represent equivalent corrections.

If the destination remains unchanged, Skip may have preserved its existing layer. If another layer appears, Add may have created a duplicate. If the original correction disappears, Replace may have overwritten the matching layer.

Before repeating the transfer, inspect the destination's existing layer name, mask, and adjustments. Do not interpret the name alone as proof that the treatment is interchangeable between products.

Choose Skip, Add, or Replace by preservation needs

Skip retains the destination layer. It suits a situation where the existing correction must remain intact, but it does not transfer the incoming layer's changes into that layer.

Add keeps the existing layer and introduces another. This can support an intentional comparison or layered treatment, but it can also create unwanted duplicates if used repeatedly.

Replace overwrites the matching destination layer's complete structure, including its mask and adjustments. It is not a values-only update that preserves the target mask.

The documented copy workflow does not currently support copying adjustments without the mask through this operation.

Remember my choice can preserve the selected conflict policy for future transfers through the Adjustment Clipboard. Therefore, review that remembered behavior before processing another product series.

Do not predict an exact brightness increase from duplicate layers. Their combined appearance depends on the actual masks and adjustment settings.

Illustrative exercise: preserve or replace

Illustrative exercise — fictional merchant scenarios. No Capture One operation, image processing, or image-quality test was executed.

Input A is a perfume photograph whose Bottle Reflection layer contains a manually refined mask around the label. A second photograph supplies a newer correction with the same layer name.

The merchant wants to retain the destination's hand-refined mask. Evaluate Skip and clarify how any desired adjustment changes will be handled separately. Replace would overwrite more than the intended values.

Input B is a revised cosmetics photograph where the team intentionally wants the complete newer correction, including its mask. Evaluate Replace on a protected working copy.

If B instead requires both treatments for comparison, Add may be appropriate, provided the team inspects the resulting layers rather than accidentally accumulating repeated copies.

The two branches differ in which existing structure must survive.

Record the transfer policy for each product set

Before copying, record the source layer, destination layer name, required mask preservation, and intended conflict policy.

After the proposed transfer, review whether the destination should contain one retained layer, one replacement layer, or two deliberately separate layers.

If the source and destination products differ substantially, inspect mask coverage independently. A matching layer name cannot validate SKU identity, product geometry, or correction suitability.

Stop when the requested operation requires retaining the destination mask while replacing only adjustment values through this copy dialog. That combination is not supported by the documented transfer behavior.

Resolve the editing requirement before applying the same remembered policy across multiple product photographs.
