My favourite family photo: ‘My mother stares dreamily into the distance, looking like an extra from Mad Men’

I found solace in looking through my father’s slides after he died. They made me gasp – and my childhood turned from monotonous monochrome to glorious Technicolor

When my sister handed me a box of old Kodachrome slides last summer, I almost didn’t bother looking through them. Unusually for pre-smartphone times, my camera-crazy father had extensively documented our lives, filling dozens of photo albums. What could the transparencies possibly reveal that we hadn’t already seen countless times? I dimly remembered him ambushing us to watch slideshows, until we were old enough to rebel.

My father died in 2012. Not long before, I had developed an interest in photography myself and, after he was gone, I found solace in my viewfinder. It was, and still is, a way of feeling connected to him. What prompted me to set up my iPad as a makeshift lightbox to view the slides was technical interest.
