I know somebody who is a keen photographer with, I think, an exceptional eye for artistic composition but who takes most (all?) of her photographs on Auto. I want to get her a book (for Christmas) to introduce her to the more technical side of photography : apertures, f-stops, depth of field, shutter speeds, film speed (in the digital age), white balance, filters, etc, etc. However, she is one of the least technically minded people I know. So that's what I'm looking for : recommendations for a technical photography book that's ideal for a non-technically-minded person.
As such, if you have, say, a PhD in engineering (like me), then I'm not really interested in hearing your recommendation, unless you are recommending a book that you've seen really help someone else you know who is very different from you. If, on the other hand, you would describe yourself as technophobic, or at least technically non-inclined, and you found a particular book very useful, then you are exactly the sort of person I want to hear from.
Thanks in advance!
