For the last 27 years, Pax Christi, Christian CND and Catholic Worker have held their annual Ash Wednesday Witness at the MoD in London to protest Britain’s non-participation in nuclear disarmament treaties. This year I put my news hat on and went down for work. The veteran peace campaigner and activist, Bruce Kent, who will be 90 this summer, has been to every one. I used a wide angle lens and fstop of 7-9. It was a grey, wet day which suited the mood of the occasion. I did most processing on one picture, of the woman tying a ribbon to the fence at the MoD, to remove nearly all colour except the penitential purple from the ribbon. You can see these photos, and an accompanying vid, in their context at The Tablet.
