Rule of thirds composition
This was originally a post in the forum thread: What should camera see?
Explaining the rule of thirds will be difficult to do without going into a wall of text mode, but I will try.
Centered subject can work if you want to accentuate symmetry and tranquility but the composition lacks tension.
If you divide the photo into three parts both horizontally and vertically you get intersections between these lines that we call points of interest.
If you reframe so that the interesting part in the frame lands on one of these points of interest, you will create tension in the photo.
This leads to our little bird not just sitting there feeling sorry for himself, but instead he is a bird on his way somewhere.
Tilted horizons is a phase we all go through. It must be tilted enough, so that it looks deliberate and not a mistake. It must be used sparingly as overuse makes the collection of photos look contrived and –Look at me! I think everybody overdoes it for a while, but it can work to get the interest of the viewer if there are only one or two in a collection or slideshow.
