This is an important subject because the misuse of a flash is the prime reason a photo comes out poorly.
Look at the following picture, taken at f/3.2, 1/60 s with the flash oriented toward the mug. The flash calculated the necessary power to correctly expose the mug. However, two problems came up:
- The scenery is underexposed, because the flash could not light up the background as it did the foreground (that’s logical). If it correctly exposed the background, it is the foreground that would have been overexposed, resulting in burnt out highlights on the mug.
- The flash created an unnatural shadow clearly visible with the handle of the mug.
This typically is the kind of photo casual photographers do.
Now look at the next photograph, which was also taken at f/3.2, 1/60 s. The only difference is the flash was oriented toward the ceiling. The light bumped on it and created a natural lighting. The problem is a point-and-shoot camera is not mounted with a flash with a rotating head.
Now look at the last photo. The flash was orientated toward the mug, like in the first photo, but the shutter speed was set at 1/2 s (with aperture still at f/3.2). The captor had the time to record the surrounding light and correctly exposed the mug. It created a warm ambiance. The drawback with slow synchronisation is you need a tripod and a static subject, or else the result will be blurry.
In my next post, I will suggest some solutions for our fellow SOTDist (yes, that’s a barbarism).
