Prosopagnosia links to ASC and how to get diagnosed?

Does anyone know much about prosopagnosia? Is there any links with autism? If so how can you get it diagnosed?

I am an autistic adult and I have always struggled to recognise places and people including myself in photographs, photographs always look different compared with what/who I visualise in my mind. In fact because of this I don't really take photographs because I don't see the point as they look nothing like what I wanted to capture in the first place.

Would welcome any advice on this

Thank you
