So when you process an image with Photomator and wish to continue processing in another application (e.g. SiverEfex from the Nik collection, which only takes jpegs or tif files) while preserving the folder structure of your disk, all you have to do is click on Export to original folder.
Then display the image in its folder (Show in the finder) and, as the exported image (in tif, for example) is in this folder, just open it with the application of your choice.
The other, more ergonomic alternative would of course be to export directly into the application. Photomator creates the export on disk and automatically opens it with the application.
