The old punch line was, "I don't know art, but I know what I like."
I grew up around people who appreciated craftsmanship, and learning how to make things, not only the easy way, taught me a lot of what's involved in being able to render something artistically. To be able to actually envision what a final result should look like and then create it is, to me, artistry. Too many people cannot do that. Myself, I am a fairly good machinist and woodworker, but I cannot approach the levels of artistry involved in creating a masterpiece. I look at almost everything with those same attempts to prove a skill set.
I've been lucky enough to know some true artists, an old friend had a career as an illustrator of children's books, another taught me the basics of photography and developing of films, and over the years I've met a number of fairly famous people who have the ability to make a living thru their creative artistry. I have some pieces gifted hanging today.
I took the basic art history courses in school, and toured a number of the worlds better museums, but it took a fair amount of time for me to develop an appreciation for the specific mediums I take the most pleasure from. And travel helped. I've bought Easter eggs in Prague, etchings of places I've been, glass I've seen blown, the occasional painting in galleries, carvings, and even sculptures. Everything on display in my home has a meaning and memory for me, and those are the values I put on a piece.
I love being able to walk through a museum and try to guess the artist/school/or nationality or the works before I read the information plaques. It's like a puzzle, or test, and it forces me to learn. I love going out an finding an exhibition going on as I travel; it gives me the opportunity to talk to the artists and I find I usually can get them to explain the processes they use in creating their pieces. Talking about the new printing processes for photographic images on glass, or metals, would never be possible if I didn't know what I do about handling films. Talking carving with a sculptor or joinery with a cabinet maker; material properties in a glass studio; or the use of layering in painting with modern acrylics are things I would never have thought I'd be able to do 40 years ago. But if I'd never got out into the world and met the people in it, I'd never have learned these things.
But as much as travel has added to my love of art, reading has likewise contributed to my understanding of it. I have to admit I still don't fully understand the fashions for clothing that people wore, much of it seems more uncomfortable than useful, but knowing something about history helps tremendously in understanding art. The influence of religion is tremendous, no matter what part of the world you're in, and major events, coronations, battles, miracles, etc, all get their strength from art. That which survives today tells us of what happened 200, 500, 2000 years ago, and what was important enough to actually be worth the effort to record it.
To look at a picture painted in 1816 and wonder why Turner made the sky so orange, tells us of the effects of a volcanic explosion in Sumatra. To see the paintings of Van Eck and realize that the middle class of merchants was gaining the wherewithal to put the time and money into having portraits painted (previously exclusive to nobles and the clergy) , to see the fresco's of Thera and realize those birds and monkeys once existed in the Med, that is a major part of the value of art.
But, in the end, if you like something, enjoy it. If you don't, move on.
