It may seem odd to you that I do this, when I obviously have a vivid imagination, but sometimes an author needs a little extra. What is fun is that I can stare at a picture of a mountain scene and imagine a walk through the woods in whatever way I want.
Do I see animals? What sounds do I hear? What time of day is it?
Not only can this be relaxing, it's also how I unlock some of the most creative settings from my mind. Pictures are a moment captured in time, but a creative writer can gaze into the misty background of a scene and see more. The mind can be quite the playground. *wink*
I put pictures on my wall of sunsets and deserts, while writing my first book, Dhampir Passions. Why? In a way, a dystopian romance requires that the setting be its own character.
Having pictures is also helpful with a characters' details page on my wall. The page contains the basics; height, eye color, weight, hair color, etc. This details page is needed because I usually have more than one story I'm writing, and it helps me to not mix up characters. I've seen it happen to other authors with their character names. A small faux paus, but one I intend to avoid if at all possible.
For now, I'm nearly done with Sindriel's story, which is the sequel to Love's Demon Ways. I still need an epilogue. That will come to me. Perhaps I just need a picture to inspire this last moment of his "happily ever after."
