Increasing dynamics

The human eye’s brightness ratio exceeds by a great deal that of digital cameras, or even the brightness limits perceived by professional film. Your camera is in trouble when dealing with huge differences in brightness as it cannot represent the view perceived by your eyes. For example, you try to photograph a landscape in the brightest sunlight. Normally, your eyes aren’t tested much by having to compensate the brightness differences between the sunlit sky and the shaded landscape parts. But not so the camera! If you measure exposure at the sky, you can only see black silhouettes of the landscape. If you use the landscape as a basis of measuring, the sky will be unpleasantly white (bleached). One solution for the problem is multiexposition, i.e. taking multiple photos with different brightness levels, and merging them.
