Unknown Mark - help please to identify maker and technique

This is a large studio pottery bowl with superb glazing. I would appreciate any help identifying the potter and glazing technique, many thanks

Im not having much luck resolving the mark.
The glaze looks like it’s been applied by partially dipping the bowl a couple of times. Maybe a Shino type glaze but I’m not seeing much of a shine on the surface in the photos that I’d expect from it. There is also a whitish glaze underneath and on the undipped areas.

Thank you for your advice on the technique etc. NaomiM. The photograph is very like mine. One I will keep until I can find the maker. kind regards

The photo is your mark. I just tried editing it to enhance the mark.

Thank you for enhancing it, kind regards
