Not a real forest in the usual sense. But, just barely real enough that you can see these.
I’ve been playing with adding textures to images off and on for years. My library of textures has grown beyond all reason.
There’s a new album of images like this at markhoffmanphotography.com in the gallery called “Current Work” which is under “Images”.
Here’s a more specific link to take you there directly: Images From The Textured Forest
These are a ton of fun to create. More are planned.
