This week's Big Picture features a photographer who left Yorkshire in the 1960s — but still appreciates the beauty of his former home.

David Hobson grew up in the Holme Valley, but has spent most of his life in Canada.

He said: " When I left in 1967, the valley was home to houses and mills that after a century or so of belching smoke had turned every building black. On return visits over the years, most recently for le Tour (who could miss that?) I’ve seen the area brighten, grow, and prosper, and realized how much I took its hidden beauty for granted.

"Today, I see where many of those dark satanic mills are gone — torn down, or repurposed. Soot stains have been blasted away from public buildings to reveal beautiful, golden sandstone while the old drystone walls still quilt the hillsides, the fields greener than ever.

"As a garden and occasional travel writer, I’ve seen enough of the world to realize that the North of England has a unique beauty that exists nowhere else. I view it now from a perspective that reveals, especially through a viewfinder, much that I didn’t appreciate when young. It’s always a pleasure to return, to witness the past and capture the vibrancy of the present.

"On the bleak, yet starkly beautiful moors, when the heather is in bloom, nostalgia tugs most hard on my sleeve."
