Framing means having an object in the foreground to give depth and interest within a photograph. For ex: taking a sunset shot just ground and sky is a little boring no matter how increadible the sky may be. Framing would be having some tree branches "framing" the vista on the edge or edges. In Photographic compostion one should not center the horizon line nor the focal point. Rule of thirds means you draw a nine point grid, like a tic tac toe box

The rule of thirds is a "rule of thumb" or guideline which applies to the process of composing visual images such as paintings, photographs and designs. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections. Proponents of the technique claim that aligning a subject with these points creates more tension, energy and interest in the composition than simply centering the subject would.
The photograph to the right demonstrates the application of the rule of thirds. The horizon sits at the horizontal line dividing the lower third of the photo from the upper two-thirds. The tree sits at the intersection of two lines, sometimes called a power point or a crash point. Points of interest in the photo don't have to actually touch one of these lines to take advantage of the rule of thirds. For example, the brightest part of the sky near the horizon where the sun recently set does not fall directly on one of the lines, but does fall near the intersection of two of the lines, close enough to take advantage of the rule.
