Once you figure out the mechanics of how a DSLR works,
getting good at the composition of your photos seems to be the 80/20 of rapidly
improving at photography.
The “rule of thirds” is the basic step for a good composition.
You divide the frame into 9 equal rectangles, 3 across and 3 down.
Many camera manufacturers
have actually included the capability to display this grid in live view mode.
Figure in a landscape
can give you a sense of how large and imposing the scene is.
Following symmetrical scenes gives you a
perfect centred composition.
Photographs are 2D by nature.By adding foreground interest and depth you can
give the picture a 3D feel.
