Photography Inside Historic Buildings

Why?
Last weekend we visited three historic buildings and I was interested (and confused) by the very different attitudes towards visitor photography.

Cameras are everywhere today. Almost everyone carries a smartphone and photography with a 'proper' camera is popular. When visiting a tourist attraction, many people like to take a photo which is more personal than the postcards available in the gift shop.

All three properties are managed by individual trusts and I was struck by their very different attitudes towards photos. For comparison, the National Trust's current policy in their properties is that amateur photography (without flash) is allowed provided that the photos are only for private use. This seems fair. 

Brontë Parsonage Museum, Haworth
No photography is allowed anywhere inside the building and several signs to remind you of this.

Armitt Museum and Library, Ambleside
No evidence of any particular policy: we took several photos (without flash) of books in the library and the nearby librarian seemed unbothered.

Elizabeth Gaskell's House, Manchester
Photography is actively encouraged - 'Fill your boots', I was told. I was also asked to share them with friends and post them on social media to spread the word.

Three historic buildings, three different approaches to visitor photography. But which one makes visitors feel most welcome?
