In the Hitched article they suggest that any good photographer would be happy to put you in touch with former clients, which is true, however we now have GDPR so passing on details isn't allowed legally. However, I'd be more than happy to speak to former couples and ask them if I can pass on their number or email, or introduce them on social media, so you can find out how it was to work with me.
I also have testimonials on my site which give a very fair review of who I am as a photographer. I go above and beyond for my couples, and I like to think I exceed just being a photographer. I love to surprise and delight
