My theory is that as with all artists you have to be emotionally involved with your subject in order to create great images. Technique is a necessary precursor; but you can't say today I'll shoot architecture, tomorrow nudes & day after natural lnadscapes, and expect to create something that grabs you. Tourists create mementos whereas the great work is created by those who live in & deeply respond to the beauty of an area.

Ansel Adams, Clyde Butcher, etc. create inspiring images of their areas; but with few exceptions create only good technical pictures of areas they visit. Weston created thousands of portraits, but they don't inspire. Reading his biography one realizes that even his pepper series evolved from his interest in food & health.

So, find a subject that grabs you, inspires you; then your images may do the same.
