“When you include angled lines, choose a perspective that allows the angles to be at least 20 degrees off-level. Anything less doesn’t look deliberate and isn’t as appealing. To control the angle of lines, change your perspective. For example, in a landscape with a straight fence through it, you could hold your camera perpendicular to the fence so that it was perfectly straight across your picture. Or, you could move close to the fence and turn left or right so that the fence drew an attractive 20 to 30 degree angled line through the landscape. However, you wouldn’t want to be somewhere in-between; a 5 degree angle would look careless and unattractive.”
