Infrared is not a new typed light. Although it has already existed in our surroundings, we could not see the light through eyes directly. By the reason which infrared images take such invisible light, the images give us to feel magical and ethereal. In the analog age, it was to difficult to keep infrared images and the procedure to take the images was complicated. Also, the wavelength taken was narrow. However, in the digital age, taking infrared images is much easier, and shooting is possible in a wider wavelength range. Automatic focus is available as well. Nevertheless, the focus of images is not so clear and the decline of the resolution has to be improved. In this article, I will shoot with the infrared wavelength range divided into narrow ranges, so I will make the chromatic aberrations due to differences of wavelength should be minimized. Through this experiment, I intend to present the improvement of the resolution and clarity in the infrared images. In addition, I will compare the infrared images to the visible-light images taken under the same condition with the experiment, and show the results.
Abstract
Infrared is not a new typed light. Although it has already existed in our surroundings, we could not see the light through eyes directly.

In the analog age, it was to difficult to keep infrared images and the procedure to take the images was complicated. Also, the wavelength taken was narrow. However, in the digital age, taking infrared images is much easier, and shooting is possible in a wider wavelength range. Automatic focus is available as well.

In this article, I will shoot with the infrared wavelength range divided into narrow ranges, so I will make the chromatic aberrations due to differences of wavelength should be minimized.
