Fortunately for most of you who are interested in using framing, humans do a great job of creating objects that are ideal for framing. Doors, windows, archways, sculptures, glasses, buildings... the list goes on and on. Just remember that although anything can be used as a frame for your subject, the best ones are those that bring context to the subject and thus improve the overall feel of the image.
In addition to creating structures that are ideal for framing, humans themselves are great for frames. A classic one is a pair of legs (especially those clothed in fishnet stockings, in my opinion ), but there are others. Arms and hands can form frames. Even fingers can in the case of forced perspective (e.g., placing your fingers close to the camera and "grabbing a distant object). Arching bodies, groups of people... the list is as long as your mind is creative.
The take home message here is that frames are all around us - some obvious, and some less so. Experimenting with framing can add intrigue and interest to a photo that it might not have otherwise, so be creative and don't limit yourself to the obvious.
Here we go. Here's an example of framing using fishnet-clothed legs:
So... see how the legs really set off the man and his car? A photo of the guy and his car may have been good on its own, but the legs (and cig) really add context. It suggests lots of different things, and gives you much more to think about rather than simply the dude and his car.
That's it for the framing tutorial. If any of you have any questions about framing that haven't been asked already, now is the time to ask. I apologize for the limited number of photos, but as I said, the type of photography I do doesn't lend itself to framing as well as other genres. Still, I hope you were able to conceptualize the images and ideas I covered.
I'll get another trivia question ready while you formulate any questions you might have.
