What is wrong with this photo? Yes - you guessed it right.
The photo is tilted. The horizontal lines and vertical lines are not aligned
properly. While it is a simple task to align the lines, people often make
the mistake of not holding the camera straight.
Before taking a photo, take a moment to observe the straight lines through
the viewfinder. Try to align the horizontal and vertical lines with the borders
of the viewfinder, unless you intentionally want the photo to be tilted.
