画像を統合すると明るさが変わってしまう
「表示中のレイヤーを統合」を実行すると、「比較明」のブレンドモード使用時にライブレイヤースタックと一致しない。
Merge Visible does not match the live layer stack when using the Lighten blend mode
Photoshop Version
Photoshop 27.8.0
Operating System
macOS 26
Steps to Reproduce
- Open multiple different Canon CR3 files as layers.
- Set the blend mode of the upper layer(s) to Lighten.
- Compare the live layer stack with the result of Layer > Merge Visible (⌘⌥⇧E).
Expected Result
The merged layer should be pixel-identical to the live layer stack.
Actual Result
The merged layer does not exactly match the live layer stack.
Although the difference is difficult to notice at 100% zoom, it can be confirmed using the following procedure:
- Create a merged layer using Layer > Merge Visible (⌘⌥⇧E).
- Change only the merged layer to the Difference blend mode.
- Compare it with the original live layer stack. If they are identical, the Difference layer should be completely black. However, visible differences remain.
This issue does not occur when two identical images are used.
In addition, images exported from the live layer stack (JPEG/TIFF) match the result of Merge Visible, not the appearance of the live layer stack displayed during editing.
As a result, the final rendered/exported image does not match what is displayed while editing.
