I don’t mean to be contrary but no it does not. It is not possible to change the “default” preset from the one set when the image is first seen by PL4. At least not in my version .
I set my default preset in preferences to the black and white preset “For Him” from the Filmpack. I navigated to a folder of previously unedited images and they were displayed in black and white as expected. Next I changed the default preset to standard . Now whenever I press reset on any edits of that one folder of images they return to black and white. The only method of applying a different default preset is by changing the filename (untested but should work) or trashing the database.
I find this illogical as the reset action resets the image to what might be an unexpected state. I would prefer if I was given the option of reseting back to the present default preset, this would allow me to simply change my mind.
