I just purchased a fantastic book called Creative Portrait Photography by Natalie Dybisz, a.k.a. Miss Aniela.
Photography has changed tremendously over the years and now virtually everyone has a camera with them at all times and considers themselves a photographer. So what makes your images worth looking at? Unfortunately as good as Ansel Adams images are I am not sure he would even get an honorable mention in todays world.
How do you differentiate your work and what is your process for creative thinking?
I recommend this book to any photographer who is trying to make creative imagery. My favorite quote from the book is "All photography is not to be viewed as art".
Fair warning: You will be disappointed if you buy this hoping to get information about a camera or lenses, camera angles, digital versus film or how to use strobes or Photoshop - it is just about creative thinking.
