I do something similar with a journal. I bought a little Instax printer recently so I can still use my phone as a camera but print out the pictures and stick them in it.

I was thinking the other day I need to go back to a physical recipe book too. I don't cook that many different things that I need to reference it for, but there was a charm in my old one of remembering the best recipes were the ones covered in spilled ingredients and filled with marginalia.
