Oak Trees

I'm reading a book called 'Zen Camera' which is an approach to creative photography. One of the early exercises in the book is to take photos without looking through the viewfinder, just hold the camera at any height and any angle and shoot. I tried this today while in the park taking 38 images. I was surprised how good the results were, I thought I would have to delete the lot but I've kept several and two, this being one, I thought were quite respectable. Perhaps I should do this more, it might improve my images!
