In his recent video release of Sean’s Favorite Photoshop Techniques, Sean uses the TKActions V6 panel to duplicate a smart object layer to make unlinked smart objects. This allows the smart objects in these layers to be independently manipulated to achieve different results on the different layers. Because unlinked smart object layers can be so useful, I programmed this as the default for the “Duplicate Layer” button on the Combo/Cx modules when it is used to duplicate a smart object layer.
For anyone used to using the V6 panel who has gotten used to this behavior, it’s easy to forget that unlinked smart object is NOT the default in Photoshop. The Photoshop keyboard shortcut to duplicate a layer, CTRL/Command+J, produces a linked smart object instead. So does the menu command Layer > Duplicate Layer… In the video below, Sean goes over the difference between linked and unlinked smart objects. It’s a bit complicated, but an important distinction to keep in mind when working with smart objects.
Personally, my use of duplicate smart objects is similar to what Sean shows in the video to double-process a single RAW file. That’s why the default for the “Duplicate Layer” button is to create unlinked smart objects. Hope you agree with this choice and will give this feature a try if you’ve not already done so.
