Tone Mapping for Graduation Photography
Tone mapping is a relatively new process in digital photography; it has been used in the past in 3D, but now it is used for image taking and editing, because it allows professionals and amateurs to digitally edit pictures into 32 bit images (increasing the dynamic range of the picture). This process is very useful in many different circumstances. For instance, you can use it in events such graduation parties and convocations, where you want to achieve high quality images, but you take many pictures at different exposures.
How Does Tone Mapping for Events Work?
A typical DSLR camera is able to capture a certain amount and quality of tones in a single image. Therefore, many elements visible to the human eye are sacrificed when you shoot a picture. Our eyes are capable of seeing a wider range of tones compared to a normal camera. For instance, if you are shooting a graduation event and there is a cloudscape, your picture might get darker than you want. The brighter details are, in this case, lost.
Tone mapping allows you to intervene digitally and create an even visual result, richer in colors and tones. In the same example, you can take four or five images of the same students on stage, but at different exposures. Then, while editing the images, you can merge the pictures in one, producing a single image with a truly large variety of colors and tones that show all the possible details in light and shadow – the same details that are visible to your eyes.
