Hi Natalie
Whilst you could potentially market to your past wedding clients, I think that might be difficult to achieve the balance discussed above.
However, there’s potential with the abandoned streets at the moment to capture some incredible and unusual images of this time. You’ve done some landscapes (Dingle Dell and Portugal etc) as well as weddings and portraits so maybe focus on those? You could sell them to the media as well as general public.
Another strange thought might be to take portraits of people online in their lockdowns (eg: using a videoconferencing app with you being the remote photographer) and then grade them so they become decent.
Hope either of those ideas interests.
