You can significantly improve many of your images by combining them with other photos you've taken. If you want to sell your work, this increases the marketability of what you shoot, and if you simply want to create beautiful imagery, it does that, too. A case in point is this traditional shot of Brugge, Belgium I added the tulips, of course, and I also inserted the beautiful sky. Now the image has more color, more depth and a lot more interest. This picture has sold, too, as a jigsaw puzzle.
