Antonio Olmos: 'I only had a few minutes with him. He told me having his photograph taken was like “having your teeth pulled out at the dentist”. Still, he reluctantly did what I asked. Once my time was up and I put the camera down, he was very kind and we had a nice chat. I am a huge admirer of his work and it was a great thrill to meet him, but I tried not to show it' Photograph: Antonio Olmos for the Observer
