Two of my favorite characters who ever hung out on this site were The Cajun Boy & Griff. Both seemed to have photography as a serious hobby, almost on a par with guitars. One thing they both did well was photograph their G&Ls in natural settings. The results were usually brilliant. Something about mixing the wood & steel of a guitar into Nature was real art. I got lots of ideas from them, as well as some coaching. They contaminated my thinking so much that I never think of taking a photo of my guitar inside my house.
Here are a few that I've taken that I'm kinda proud of. Please add some of your own "Guitar In Nature" shots.
