HEIC
I happen to like the HEIC format for my images, and I am wondering why when I export an HEIC image from Photos it's converted to JPEG. I want to keep it HEIC.

You can export the image as HEIC, if you use the export command "File > Export > Export unmodified Original".
Then the original will not be converted when exporting it.
If you have adjustments applied to a photo and want to export the adjusted version, you can only export it with "File > Export > Export ... photos", and Photos will render a new, adjusted version. You can select either JPEG, TIFF, or PNG, but not HEIC.
I also want to keep my photos in the HEIC format, so I export the edited versions as TIFF files (because this is a lossless format), and then use the Preview.app to convert the TIFFs to HEIC images for a better compression to save some storage.
