I am choosing a textbook for an introductory course in photography taught with digital tools. Having trouble finding a good textbook that will cover the basics of exposure, aperture, etc. along with helpful digital information. I don’t want this to be a how to do cool digital tricks class. It is about a more real, in-depth understanding of photography. Yet I also don’t want a book that is hopelessly out of date for a student using digital media. Any suggestions?
