Good Smartphone Photography
You might be inclined to place the subject in the center of the frame. As unnatural as it may feel at first, use the rule of thirds instead. The thinking behind the rule of thirds is to break the frame into three equal sections, both horizontally and vertically.
Some smartphone cameras have a setting that will place these lines there for you to see as you take the picture. The points where these lines intersect are where you should place points of interest in the frame. You’ll be amazed at the difference!
Natural lighting will almost always produce a better shot with realistic color than a photo taken with a camera flash, especially for portrait shots. If it’s cloudy or you’re taking a shot inside, look for strong artificial lights or ways to reflect what little natural light there is.
