Softcover book of color photographs with fairy-lore text. That is, images are actual unmanipulated photographs but the text relates these to fairies. I am confident it is a book of photographs as well as relating at least some of the photographs to fairies. Other recollections are softer.

New format, same book stumper solving.
This reminded me of The Fairies https://www.amazon.com/Fairies-Photographic-Evidence-Existence-Another/dp/0060282347 but these photos are staged/manipulated. I think I recall that some of the pictures in here are just of woodland scenes, though.
I found the book, it is Ellen Fenlon’s _Fairy Church in the Woods_. It was easy to find once I changed my search to ‘woods’ rather than ‘forest’.
