ALL forms of art are technical. Don't devalue the importance of photography by saying that it is a technical art. Most people who say things like that have never painted, made ceramics, made an etching or a lithograph, or done sculpture. I've done all of those in addition to photography. All form of art have technical knowledge needed to make the art. I invite anyone who doesn't think that to try making an oil painting on a piece of paper (oil paints rot paper unless you put down a protective coating on the paper before painting), or try painting a fast drying pigment layer on top of a slow drying pigment (the painting will crack as it ages). Lithography, etching, and ceramics are so rigorously technical that you cannot even produce a crappy print or teacup without a deep level of technical practice and knowledge.
As to making art with photography: No great artist has made great photos of something that didn't mean something to him or her. Ansel Adams loved nature and photographed it. Alfred Stieglitz photographed his wife, Georgia O'Keefe. Cindy Sherman photographs her kids. William Eggelston grew up in the south and wanted to document southern life and culture. See what I'm saying? Amatuer photographers fall in to the trap of trying to go make pretty pictures, so they produce a bunch of boring photos that don't mean anything and don't fit together as a mature body of work.
