You will find an increasing number of my photos at a website called Unsplash, the photos are high definition, do not show a watermark or logo and are royalty free for you to download and use in any manner you see fit.

Click on a photo in the album and it will take you to a larger image with a link option to its particular download page  in Unsplash, or use the other links for a broader selection.
