I'm guessing more than a few photographers are like me when it comes to reading about photography. I buy and/or read most of the U.S. magazines that cover photography--e.g., popular photography, shutterbug, photo pro, and more--as well as books and internet sites devoted to the art.
but i began to realize that, apart from information about new products and technologies, i was often reading about stuff i already knew. in fact, when these magazines and other media included photoshop-related articles, I found i was getting the most out of whatever it was i was reading.
so i started spending much more of my reading (learning) time with books and magazines and internet sites devoted to photoshop. after all, most photographers have now embraced digital photography on some level and many, like myself, now find that almost all of their photo work is performed digitally. this means learning a whole bunch of new stuff about photographic post-production. and let's face it, photoshop is not something you become competent with after a few uses.
so now i spend about 70% of my time learning about photoshop, it's uses and capabilities (and how to use them). in my opinion, spending the time i now spend improving my photoshop skills has not only changed the way i capture images, but--IMHO--improved it.
