I was lucky enough to spend a day at the UK Wolf Conservancy Trust near Reading. As you will see from the "Mug Shots" the animals were magnificent althogh difficult to photograph in spite of the efforts of the staff and volunteers at the Trust. The light levels were awful and most photos were taken at between 1500 and 3600 ISO. I can heartly recommend a visit if the opportunity occurs. Website https://ukwct.org.uk/
