We all need to occasionally practice some composition… the easiest and most rudimentary method is with the rule of thirds.
Like always, the camera doesn’t matter. You can be using a point and shoot or a high end DSLR – if your image is not pleasingly composed, it’s not pleasing.
It’s been written about all over the place, o I’m not going to go in to detail about explaining theory or overanalyzing. If you want to read a bit about the ‘rule’, go here: http://en.wikipedia.org/wiki/Rule_of_thirds.
That said, go out during your next photowalk or cameratime and pay attention to your composition and really try to intentionally explore using the rule of thirds. If your camera has an overlay grid for the screen or viewfinder, thurn it on. Pay attention to it… and shoot away!
…and here is my above image with a grid overlay… just to show how the formula was intentionally applied in the photo.
Oh – and just for the record, rules are meant to be broken. Just because an image doesn’t follow the rule does not mean it is poorly composed… but as a guideline, this is a good place to start.
